Its been years since I owned one, but I just used one down in my basement and I'm puzzled. I dont remember two different colors. I have some spots that are glowing yellow and look like clear biologic residue of some kind (vomit for most) and I have other spots that are blue but not solid, like blue sparkles or something. Its the blue that is really puzzling me. I did a quick search online, but got a lot of junk results so I was hoping you all can help.
Thanks!
Thanks!
