yes it is. You're done but not done. Whats worse is when your clean up uncovers a "What is that?" object. Here's mine. I have a large clear area in part of my kitchen. Through tthe winter it held many things mostly waste&demo. but was also an area I could use for staining. When I stained I made sure to cover the floor. So I was bummed to find the following: it appears to have dripped into the image area. And I've got no recollection of wiping causing that big smear. Simple water did nothing. I'd done some chemi-stripping (see my other threads) but not in the kitchen and was _really_ careful with the residue when disposing. Besides that residue was a dark brown -- not this red-tan. ok. Lets try some chemicals: Strypeeze -- did nothing except eat the linoleum. Paint thinner -- nothing. brush cleaner (a green one) -- nothing. Mohlenburger(?) foam&reside remover -- nothing -- but it did seem to work a bit on the gray dinge. note for the future. Only glues I used were wood glue -- and that dries yellowish M-burger makes another product for res removal haven't tried it, The crunchy stuff is _hard_ a spackling/putty knofe wouldn't even crack the crunchy stuff. I know you folks weren't here. but do you recognize the gunk? Any ideas on dissolvers/cleaners? I haven't tried Oxalic acid yet -- that actually did a great job of releasing some wood prservative/stain that got on some formica and sat for years b4 i tried cleaning it. thanks for any ideas!
