We bought a new white linoleum floor to which we added a couple of bathroom rugs. When I went to pick up the rugs to throw them in the wash, I noticed the floor had yellowed underneath the rug. The stains were same shape of the rugs that covered it. The floor was meant to look like white marble now it looks like yucky yellow snow. How I can get these stains off? Will putting the rugs back down cause it to yellow once again? Shouldn't there be a warning lable on these rugs!
use laundry detugent and water watch this video it will help Goodluck after clean do not put those rugs back down
Yep, the backing on the rugs gives off gasses as they oxidize. They are most likely gasses from plastic (hydrocarbon) or PVC (chlorides). It is possible that the discoloration to your floor is permanent. You can try putting some lemon juice on a small area and leave it there to dry. If you see a return to the original color, treat the rest. The other thing is a household ammonia test. Same thing (but open the windows and keep your head away from the product). Since you will now be testing acids and alkalies to see if you can reverse the problem, the only other thing to test is a solvent like white spirits. Do this one last. The rugs will continue to degrade but less than when new. You are right that there should be a warning on these rugs to not place them on certain surfaces but you know manufacturers, put it out to sell and then deny any liability.
