Their is a black spot on our white carpet. I think it's been their for at least 2 years, but we never realized it was their. We've tried 2 brands of carpet remover, and it only faded a little bit. We tried oxy spot remover, and it didn't do anything, please help.
try crud cutter and let this sit for a few min scrub it and blot it up you can get this at home depot or lowes or a paint store
Could be that whatever was spilled on the carpet might have molecularly bonded. You might want to try heat and scrubbing. Take wet wash towel and microwave then rub or use an iron over the wet towel directly over it to dislodge the bonding components. CAUTION--the iron method can cause permanent damage to carpet fibers if applied to hot.
buy a stain devil thats made for biro nailvarnish or paint make sure you rinse well. its worked on everything ive needed it to even hair dye!!!!
