Quoted from OTTOgd:Melamine foam with 99% alcohol is great. Just go slow be careful. And wipe sludge with a clean towel frequently.
I wear heavy duty gloves when digging in. When that sludge dries, it's stubborn to remove from anywhere.
Work looks very good, nice job cleaning it up.
Can you clarify what type of alcohol you're using? Common drug store rubbing alcohol is IPA (isopropyl) and is at 70% concentration. Just curious if you found a better variety?
Thanks
