Alright, let’s talk about cleaning the inside of a motorcycle helmet. Mine was getting pretty funky, you know, after riding around, especially in warmer weather. Sweat, hair stuff, just general grime builds up. Smelled a bit ripe, honestly. So, I decided it was time to give it a proper clean.

Getting Started – Taking it Apart
First thing I did was grab the helmet and find a clear spot to work, like my kitchen counter. My helmet has removable cheek pads and a liner, which makes things way easier. If yours doesn’t, you’ll have to work around that, maybe just wiping the inside down more carefully.
So, I started gently pulling out the cheek pads. They usually snap in and out. I took my time so I didn’t rip anything. Then, I removed the main liner, the part that covers the top of your head. Again, just carefully unsnapped it or unclipped it, whatever system it used. I laid these pieces out.
Washing the Stinky Bits
Okay, now for the actual cleaning. I didn’t do anything fancy.
- I filled up the sink with some lukewarm water. Not hot, just warm.
- Added a little bit of mild soap. Some people use baby shampoo, I just used a gentle hand soap I had. Didn’t want anything too harsh.
- I took the pads and liner and just dunked them in the soapy water.
- Gently squeezed and massaged them. You could see the dirty water coming out. Gross, but satisfying!
- I didn’t scrub like crazy, just worked the soap through them.
- Rinsed them really, really well under cool running water. Squeezed them gently until no more soap bubbles came out. This part’s important, don’t want soap residue left in there.
Cleaning the Shell Interior
While the pads were out, I tackled the inside of the helmet shell itself. Since mine doesn’t have much fabric left inside once the liner is out, it was mostly the hard foam (EPS liner) and some plastic bits.
I just took a damp microfiber cloth – slightly soapy water again, then wrung out really well – and wiped down the entire inside surface. Got into the nooks and crannies best I could. Then I used another cloth, just damp with plain water, to wipe away any soap film. Made sure it wasn’t dripping wet, just damp.

Drying Time – Patience is Key!
This is super important: Don’t put wet pads back in your helmet! That’s asking for mold and more stink.
I gently squeezed out excess water from the pads and liner, careful not to twist or wring them too hard. Then I laid them out on a clean towel, somewhere out of direct sunlight but with good air circulation. I just left them there overnight. Seriously, let them air dry completely. Don’t use a hairdryer or put them in the dryer machine; heat can mess up the foam and fabric.
I also left the helmet shell upside down to air out properly.
Putting It All Back Together
The next day, once everything was bone dry – I checked carefully – it was time for reassembly. It was basically the reverse of taking it apart.
I snapped the main liner back into place first, making sure all the clips or snaps lined up. Then I did the same with the cheek pads, snapping them back in securely. Gave everything a little wiggle to make sure it was seated right.

And that’s pretty much it. Put the helmet back on, and wow, what a difference. Smelled fresh, felt clean. Way better riding experience when your helmet doesn’t feel like a swamp. Took a bit of time, mostly waiting for stuff to dry, but totally worth doing regularly.
