Who's using it and what are your thoughts. I use the liquid 90 but without the biosolve. Im thinking of switching to the powder (90/bioslove). Have you noticed a difference btwn the two? The specs read that the Biosolve version doesnt leave a tacky residue but does leave a crystalized dust that can be vacuumed when dry. Do you go back to vacuum the following morning? Do you tell the client they must? Is it such a small amount, do you let it ride and whenever they get to it they get to it? Im gonna go ahead and buy some and I know Ill be using it for my dr. offices but I have a daycare center tomorrow night and dont want the little buggers crawling around particles. Let me know your thoughts.
