The eraser sacrifices itself too (this is how they work). Too much or too hard is bad, yes. Light thoughtful application can be OK. You’re trying to get the eraser to grab the junk out crevices other cloth types cannot. Also note, even cloth can damage the layers if used too vigorously.

Start with the mildest form of cleaning possible. Work your way up if needed and understand what reasonable correction can be achieved per your situation.

Any thoughts on rubbing alcohol / isopropyl alcohol? I see this often mentioned in detailing forums.

Its a pretty aggressive solvent, do not use it on leather, or paint for that matter. Some plastics should be ok, I guess.

Heavily diluted to under 20% concentration, isopropyl alcohol should be OK to use. Not as a primary cleaner, but to clean off any left over residue from whatever you used to do the main cleaning.

It's common to use it on paint too, as the final step before you apply a sealant, to ensure you have cleaned off all residue from polishing compound.

Hmm good to know.

Intersting to see, as I some swear by it.

IPA is fine to use. I use it.

To strip off grease, yes. I dilute it and do wipe downs often with it.

Today, just for fun I tried Alcohol Kentonatus 70% and even a little aceton on a wheel that I couldn’t be bothered with if things went bad.

Can say “wow”, but just see this:



That’s not light. I did the outside of the rim, not the back. The difference is just silly. It just came off with ease.

One thing though. When I see all the black gunk on my cloth, I do wonder if it’s gunk/grease/skinoil I’m taking off, or simply rubbing of the paint/dye. Which would make the result less nice.

Ps Aceton is probably too aggressive, but just wanted to see what it would do.
