Short story is this product is useless.
does an awful job at cleaning the helmet, I recommend using hand soap or shower soap instead, it does a much better job.

From my original review:
It leaves your gear smelling fresh, If you apply a lot of of foam, but it won’t do a better job than hand soap.

I used Lano hand soap to clean it,So far Lano soap & Zalo (Zalo is a quite common dish soap which a lot of people use to clean their bikes, not perfect for drivetrains,which Muc off degreasers do well and getting that brown color off you bike, which the last one Muc-Off Nano Tech Bike Cleaner does a great job with.) has been very good at cleaning all kinds of things out of my hands, apart chain lubes and stuff like this, But for cleaning stuff soaked in sweat it works great. So I had to try it.

With these 2 soaps you can see the helmet the effect of the soap quite fast.

with these 2 soaps I managed to clean helmet inserts so there was no dirty water coming out when rising off, which Muc off fresh foam did not, when rising off, there were dirty water after many tries, even after applying the foam and let it soak in and and rub with a sponge, there were still very dirty water when rising off many times.

Most dish soap will do the job, But make sure you don’t use to soaps/cleaners on helmets that can damage the materials.

Muc off fresh foam can clean lenses filled with dirt, but not much else.

Getting the sweat soaked helmet inserts, or adjustment straps clean & completely without a stink is impossible.

I even Tried to clean my Forest smelling Five ten Freerider shoes, which did not work, the shoes still smelled like forest, even after applying a lot of foam many times with aggressive cleaning with a rag.

Another bad thing about the foam is that it runs out way too fast, but with liquid soap or solid soap, last way longer.

Finde es ein gutes Produckt und einfach in der handhagun. Die Pads wasch ich immer mit der Radbekleidung mit. Der Helm riecht nach der Reinigung wieder angenehm.

Yes, mein helm riecht gut

Reinigungsleistung am Rucksack in Ordnung, Gerüche wurden entfernt. Durch die Konsistenz wie Rasierschaum aus der Sprühdose allerdings schwirig anzuwenden. Mit etwas "eintupfen" geht es aber.
