Posted 03 June 2010 - 05:14 PM
So i'm a bit of a clean freak and I just started at a new lab and there are these unidentifiable white, powdery looking stain on my new lab bench top.I tried cleaning it with 70% ethanol, 100% isopropanol, soap, water, but no luck. is there any solution out there that can get rid of this stain?
thanks in advance

i think they are stains rather than some form of a salt precipitate.........any effective chemical that might help with the removal of stains out there???
thanks in advance

I used that to clean the counter top of the chemical room in my new lab. Similar to yourself, I had a counter top covered in something that didn't quite go with either hot water or 70% ethanol.

If you got vim cleaners, try it. It works for me too.
