Very strange, carpet is a cut pile loop pile blend. The kind is straight lines of each. The carpet was very crushed and dirty right in front of where a couch was sitting. Hit it with prespray and it turned light pink. Not like a spill as in circular or splatter in shape but the pink is only on the top millimeter of carpet fibers and is ONLY on cut pile yarns, not the loop pile....Doesn't rinse out, doesn't transfer to towel. Reducing didn't touch it. Only noticed in that heavy crushed area not where else in the house. I'll attach a pic but it's hard to make out. Any ideas? My prespray I was using was Saigers Code Red,coincidence that it's got a pink color? I have never had an issue with it before and the rest of the carpet didn't turn pink.
