Been using the Ladder Helmet for about four months now, still holding up great. After a lot of use though, I noticed it was getting pretty dirty, and the clogged rubber could mark up walls. I gathered nine different chemicals (Bioclean isn’t in the group shot, as it was an afterthought.) Each section of the Ladder Helmet was scrubbed for approx. 20 seconds.
As you can see by the results, the Tilex with Clorox practically made it look brand new. I think Bioclean did a pretty good job too, and I’d imagine that a few more of us will have that readily available.
Let me know if you find another great cleaner for it!
