For the inside of the helmet I got it which was already in pretty good condition. Apart from the nice smell it leaves in the end I can't say that it cleaned the few things it had in the helmet. Maybe I didn't use it properly what can I say. Anyway in the end the sponges ended up in the washing machine again

It doesn't make it look like new or like the cushions have been washed well. But the result is satisfactory.

For use on a motorcycle helmet, I have no opinion. I bought it to test on an ergonomic pillow and a fabric gaming office chair. I have a shaved head, so in the areas where I touch, it collects odor. Both were noticeably cleaned with the use of the foam. I didn't particularly like the smell, but it's not unbearable for me. The pillow had a less intense smell from the beginning, which completely disappeared in about a day or two. The smell remained in the chair for about 5-6 days.

In a few words, it's worth it because of how well it performs on the cloth when wiping off foam. It's at a regular price and leaves a clean helmet with a light fresh scent.

Out of all the cleaning products I have used, this one cleans the interior of the helmet. You can see the result both on the cloth you wipe the foam with and on the interior of the helmet. The rest of the products are only for maintenance.

I did not see any difference in cleaning with this method. It also leaves a smell that is tolerable for some but not for others. I returned to the original method of cleaning with a basin of water and a little laundry detergent

Awesome!!
It does its job very well!!
The "dirt" from the helmet sponge is gone, it cleaned the helmet nicely and left a pleasant scent!!
I recommend it for refreshing..

Very good, easily removed dirt from the helmet and left a very nice smell, it does exactly what it promises without fooling around!!

It smells amazing and the blackhead stays! It cleans fantastically.. It takes a little time to understand how it works and then everything is a piece of cake!
