I'm posting this so that you don't make the same mistake!

I got lazy and I hadn't cleaned my Bell Super 3 helmet at all this year. My excuse was that I hadn't been doing much riding over the Summer. Being mostly bald, the sweat pads were in direct contact with my skin, so they got sweaty. When I restarted regular riding, the skin on my head started to get itchy and flaky. Right or wrong I decided that maybe my helmet was overdue for a good clean. I used to soak it after EVERY ride and then dry it, but recently the sweat-soaked pads were just left to dry (fester?) Disgusting I know, but I'm a flawed human-being.

Yesterday, I took action and I thought that instead of soaking in a diluted laundry disinfectant (my usual once per month clean), I'd go for an all-out "100% guaranteed to kill all known germs" solution. I sprayed the inside of the helmet with 100% iso-propyl alcohol (IPA). IPA was what was widely used during the pandemic to sterilise surfaces. I made sure that the pads had soaked it up by pressing on them a few times and re-spraying (I wore nitrile gloves). Then I hung it up to dry.

When my wife got back, she commented that my helmet looked very dirty. What!? :eek:
The IPA had dissolved whatever crap was in the helmet and then run down and collected underneath the helmet and proceeded to eat away at the outer coating/layer of the helmet. It was a mucky white colour on top of my satin black helmet. Aaaarrgghh, what have I done! I wiped off the worst of it and dumped the helmet in a basin of water, then dried it as best I could and left it to dry. Come the morning it wasn't as bad as it had looked, but still not good. Its now a matt black with dirty grey streaks all over it. I could not feel the slightest difference between the grey bits and the black bits, so maybe the damage was not too bad? :unsure:

I thought about it for a while. My wheel rims go a bit like that during the Winter, and Silicone Shine restores them to brand new. While I was searching for it in my recently re-organised garage, I came across some black body-coloured car body polish and an old tube of chrome cleaner (very mild abrasive).

Wary of my IPA mishap, I used the chrome cleaner in an unobtrusive spot and hit pay dirt! Five mins later, I'd done the whole helmet and all of the streaks had gone. But it looked a bit dull. Time for the Silicone Shine. And...... it worked! :love:

Hmm, I just noticed that the 1st pic was in the kitchen, and the 2nd was taken in the utility room, hence the different sink tops and worktops (just in case the eagle-eyed among you had nothing better to do and were watching). :)

PS: What I should have done was to remove the pads and clean them separately. But on previous helmets, doing that led to a degrading of the Velcro attachment and the need for a new set of pads.....which were not available! So, I got into the habit of cleaning the whole helmet. That worked a treat until all of a sudden it didn't!

Well…this post might have given me the push I needed for a new helmet. 🪖

I’m a Bell Helmet user also. Nothing else fits my tomato comfortably. I have a few types but they all have the MIPS in common. I prefer the convertible and full face. Neither are cheap.

Apparently I don’t see dirt ( so I’ve been told by the boss) and I haven’t given my helmet the smell-test either. I simply wipe away any debris or road-salt with my glove. (Man-cleaning, right?).

I’m not completely folically challenged yet but the race is on. There’s enough hair left on my head to be a bother. (Reminds me of a joke my bald brother told me once …some other time though.) I wear a baseball cap most of the time when I wander into the public.

But the full face bell convertible may have saved my life once. When I shared the story with the local Bike Shop and Bell they replaced the destroyed helmet for free.

So apparently there’s an expiry date for our helmets …and I’m almost there for my well used helmet. I don’t use any cleaning fluids or any chemicals on my helmets. A damp wet cloth and a place to dry.

My Melon Matters😉.

@Stihldog You said "I don’t use any cleaning fluids or any chemicals on my helmets. A damp wet cloth and a place to dry."

What I was trying to clean was the sweat pads and the straps that also soak up sweat. Normally, the only cleaning the shell gets is when I wipe it dry after I take it out of the water. I never for a single moment thought that the IPA would etch away at the shell!
Dumped in clean warm water after every ride, then dried is all it normally gets. Then once per month or so, it gets the laundry disinfectant treatment. If it's safe for clothes, it safe for my helmet is what I thought and it has proved to be true.
 
I have an assortment of lotions and potions for cleaning bike parts …but I am not a chemist. I’m probably a bike-cleaning-abuser. Except when the road-salt sprays on my bike, my butt, my pac, my back and my helmet. (Oh! And my mouth). Thankfully I’m only on the pavement for less than kilometre. I’m sure I look like a zebra after that when it rains.

Once in while I drop my gear in front of the washer and dryer and it magically appears clean the next morning. (How?)😉
My well used helmet is starting to fall apart and the expiration date is close. The chin strap is getting worn but the clip still works. The new magnetic chin clips seem good but man!…sometimes I feel trapped and start to panic when I try to remove my helmet. . That must look funny 😄.
 
Expiry Dates! On a helmet!

What's all that about? Does it go off just by sitting there? In which case my DH helmet safely stored in its cloth bag pretty much ever since I bought it (my last hurrah on an mtb, so more than 6 years) should be a pile of bits by now. I'm not going to have a look to confirm it. :rolleyes:

Apart from the two I currently have, I have broken every helmet I have ever owned, either by crashing, riding into low hanging stuff, or by attrition. That last one means an accumulation of knocks that each one by itself does not break the helmet, but one day you notice that the shell is no longer bonded to the core!

My current trail helmet, the one I posted about earlier has a manufacturing date of 04/21. That makes it almost four and a half years old. During which time I have ridden about 5000 miles. Apart from yesterdays' chemical mishap, it is perfect. There is no Best Before Date label in the helmet.

I've just been out to the garage to locate my spare new helmet, another Bell Super 3. I was looking to see if a best before date had been pasted inside the new helmet.

What a shock! :eek: Instead of being brand new, it is my old one that I cracked the shell right through and with a dent in it. I had continued to wear it until I managed to buy a new one. And then I kept it for use in case I wrote off my current one completely, on the grounds that it is better than nothing! I guess I had forgotten the important details. :( Bloody hell! I had failed to buy another new Bell Super 3 when they were on offer because I thought I'd already got one!
Getting old has its downsides. :(
 
Fortunately I still have a full head of hair but if I did not, I would not be riding with a bald head a gainst foam. ....some sort of skull cap required. That said I dont remember any occasion when I suffered a sweaty head in any helmet I have...maybe you are not riding fast enough to vent air through it :p or your helmets are badly vented. Even in the hottest heatwave ever recorded ( according to the climate change gurus!!) this year, my head stayed cool.
The helmet you featured in the first post may well now look ok but I doubt it is structurally sound now. Most polycarb helmets even advise a gainst stickers. Regardless, its age is sufficient to suggest it s hould be replaced. My helmets are by POC or Smith and I can thoroughly recommend either.
 
You should NEVER put any kind of chemical on any type of helmet; biking, climbing watersports, etc.
Chemicals, even mild ones, can do huge damage to the structure of the materials that the helmet is made from, and much of the damage is not visible.
Even the glue used to attach stickers can cause this type of damage.
You might well only find out about the damage when your helmet splits in half, followed by your head!
Likewise, the materials can break down through exposure to UV light, or just through internal chemical breakdown through time, which is why all personal protective equipment such as helmets are issued with an expiry date.
Your helmet might look lovely but it might well be a death-trap.
I am writing this as somebody who has been involved with PPE and safety for over half a century!

Yeah, I heard the glue from sickers can slowly cause damage to the shell. The foam, or (polystyrene?) can become unknowingly fractured after a bump or crash.

I guess it’s time to get a new helmet …and find another location for my PokeMan stickers.(sad face emoji )
 
This all just prompted me to go look at the manufacturing date of my Bell Super 3r, which is largely my go-to for all my riding.
Turns out it needs replacing according to Bell's recommendations: Replace every 3 years - Bell
My other open face Bell helmet is about three years older than my convertible, so I am thinking that maybe I should be looking at replacing that...
Yikes!
Goodbye other upgrades and hello new helmet, I guess.

I think I’m in the same boat. That Bell Full Face convertible was stupid expensive …but it’s good for a few more years yet. My daily rider is almost due (they melt into a big blob when they expire apparently 😉) so I’ll replace that soon.

3 years eh? Hmmm 🤔, time to rethink those upgrades.
 
I sweat from my head a lot and it seems to destroy the foam lining between 12 to 24 months, where the foam just falls apart or it comes unglued from the thin fabric that makes it stick to the Velcro pads. You can buy pad kits but I find that by the time your pads need replacing there's a new model out and the latest kits don't always fit. I have when available, bought a pad kit at the same time as purchasing the helmet.
 
Some of these should work well for bike helmets. I have the Helmet’in for the inside of my motorcycle helmets.

Is the shell still stuck to the polystyrene ?.. seen some helmets have a slight void between inner and outer shell.. suppose fluid could have collected in the gap / void ?… …
 
Just as examples, my wife pays to ride at a local stable yard once a week......they check riders helmets each time and will not allow the use of a damaged or out of date helmet...or one not conforming to the latest standard. The same applies to my mate when he attends a MX event. For those of us just getting out on our bikes but not in organised events such as races etc, there are no checks so it is down to us to make sure our helmets are safe. @steve_sordy has highlighted an important issue......knowing that may soften the blow of having to buy a new one
 
Three years! Is that all? Does not seem enough. But most of my helmets don't last that long anyway, due to my general clumsiness and unplanned dismounts. The fact that my current Bell Super is almost 50% above the recommended replacement life has come as a bit of a shock.
Alarmed by some of the comments, I have given my helmet a very careful and close up inspection. I can see no cracks in the polystyrene core, no dents or chips in the shell and the shell is still firmly attached to the core. I have tapped it all over and cannot detect any hollow sounds. Apart from a few scuffs, and a slight haziness on the shell, it still looks new.

However, as I mentioned in a previous post, I thought that I had got a spare brand-new helmet in the garage, but sadly only the previous old one! Therefore, I will start looking for a new helmet and when I get one, the one in the garage will be replaced by my current one as an emergency spare.

I'm glad I started this thread. Thanks to all that commented :)

Thanks for the credit @Mikerb but it was not planned, the issue just up came during the thread. I had not realised that helmets had a life measured in time elapsed. I had thought it was up to the user to identify that the helmet's utility had passed.

I would heed Nicho's advice and just bin it tbh. The damage may never be visible and only become apparent once the worst happens. Helmets are not something to take a chance on.

definitely a no no using isopropyl on helmets - it will affect the strength of polystyrene and to a lesser effect polyurethane
you might get away with a small amount for a short period
as for a shelf life on unused helmets - it's bullshit - unless it's been exposed to UV during storage - or a cheap adhesive has been used somewhere - nothing will have deteriorated.
 
I looked into mine, Its definetly 3+ years old

The Seven iDP Project 23 Carbon helmet does not have a set replacement time from the manufacturer, but helmets generally should be replaced every 3-5 years due to wear and tear or immediately after any significant impact or crash. You should also replace it if there are visible signs of damage, like cracks or worn padding, or if it's been exposed to extreme conditions.
When to Replace Your Seven iDP Project 23 Carbon Helmet

  • After a Crash:Always replace your helmet immediately after it sustains an impact, as its protective capabilities are compromised, even if there's no visible damage.
  • Every 3-5 Years:This is a general guideline for helmets to account for wear and tear, UV exposure, and material degradation over time.
  • Visible Damage:Inspect the helmet for any cracks in the shell, signs of significant wear on the padding or straps, or any other deterioration.
  • Unknown History:If you're unsure how old the helmet is or if it has been in a crash, it's best to replace it for safety.
Manufacturer Policy for Crash Replacement
  • 7iDP offers a Crash Replacement Policy for all its products, including the Project 23 Carbon.
  • This policy provides a 50% discount on a new replacement helmet if the current one has been damaged in a crash, ensuring you can get back on the trail safely.

have you dinged it at all? left it in the sun for extended periods? otherwise you can probably keep using it

Intended or not it served to inform others......precisely what a good forum is best at.

....you can hide it from the sun when it is stuck up on your head???? UV has a big effect on a lot of materials including polycarbonate and carbon. For example, carbon composite uv protection is achieved to a degree by using a specially treated epoxy resin and uv resistant paint or lacquer coatings.

I was thinking more like left it on the parcel shelf of your car for a week in a heatwave - rather than general use
I expect all reputable helmet manufacturers would use polycarbonate with UV stabilisers in for the shell
I also would expect very little of the impact strength to be derived from the shell
hence the results given in the link I gave... Helmets that had been in use for 20 years were tested!

If I told the wife I crashed in it (see YouTube channel) she wouldn't be surprised :lol: but she is also passed caring what i buy for my bike. I Spent all summer in my open face, very little in this full face, now with the winter I'll keep my eye out for a replacement, i think?

mine watches me crash on a regular basis - and she rips me a new one every single time!
I'd say it's 99.9% going to be absolutely fine after 3 years - unless you've dinged it - bit of a controversial view perhaps - but having said that there are some good sales on! if you're XL tweeks has em for £75 and tredz has them in various sizes for £110 at the mo.
correction the £75 one is GRP
