White spots on lab bench
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

and the hypochlorite worked fine ...

...except casandra's that belong to the funniest, most interesting and imaginative (or over-imaginative?) ones, I suppose.

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.
