How can I remove this from the floor.
What is it. Photo is out of focus.
Not sure what this is, but it appears to be where maybe a magazine or papers were on the floor and got wet?? If it is just paper residue, clean with a plastic scrubber with no cleaner, while dry. If it does remove the residue, repolish that portion of your floor with a matching floor wax and buff to shine with a dry cloth.
Sorry but I can't tell from your photograph what that is. Do you have one that is in focus?
Get it wet and scrub it away with a s sponge. If there are trouble spots left, carefully use a razor blade to get the rest.
I have laminated wood floors and I use a "Pro Caulk" tool as a scraper to remove any residue from my floor. You can moisten that area prior to use or try it without water first to see what happens. (The Pro Caulk tool came in a set of different shapes and sizes and is used to shape caulk lines. It is more or less a dense rubber or plastic hand tool that comes to an edge which is perfect as a scraper without doing damage to my floors.) It was suggested earlier to use a razor blade, however, I wouldn't use one on anything other than tile or unfinished concrete. Rubber or plastic is a safer bet.
You need to dissolve the material that is stuck before you can work it loose. Water is the safest solvent. Some soaked paper towels should do the trick. Give them a few minutes and try to scrape up the stuff. Definitely use a plastic scraper of some kind. If adhesive is involved, a scrub with some baking soda paste or Goo Gone could help. None of these things should damage the surface of your laminate floor. Remember it took time to get like this - so be patient and give it some time to be removed. You may have to repeat the process more than once.
That 's carpet waste
