i used filtration line cleaner on white berber carpet and went back a few days later to check the results. there appears to be rings around the spots throughout the carpet. it looks like water rings… has anyone had this occur? if so, what will take this out?
usually the filtration is along the walls and heat vents.i have seen it also in the middle of carpet coming up from plywood seams.also by door ways where air flow is restricted.what spots are you referring to ?and what color were they ?did you have to flush anything out also?rust remover and orange deodorizer can remove water marks.you might try that then flush it out after if those marks are dark.
