My carpet has a mystery stain. It's very sticky and black and ground in. I have tried goo gown and soap and water. I need some sort of heavy duty carpet cleaning suggestions.
Hello, Adding soap to the sticky and black ground in mystery stain is just making it worse. You are adding a surfactant (Soap) that gets sticky when it dries. You need to find out if the stain is a oil ( like food dropped ) or sugars like soda pop. First thing you want to do is get rid of the soap residue. If you have a wet dry vac. Get club soda and pour it onto the stick black ground in mystery stain. Use a soft shoe brush and start brushing the stain. If it is turning foamy you have to get DEFOAMER. Spray it on the carpet till you do not get any foam on your brush. (It cuts soap bonds so you can get the soap residue off the carpet). Keep adding club soda. Extract the club soda from the carpet. The black and sticky should start to go away. You should be left with just the original stain, or it should be gone. If you have no foamy residue and it still is sticky you need a solvent because it is an oil based spot. I don't know where you live but if you look in your local yellow pages for Carpet Cleaning Supply stores you can get Defoamer and Solvents to clean the carpets. BE CAREFUL WITH THE SOLVENTS USE AS LITTLE OF THE SOLVENT AS POSSIBLE. IT CAN DELAMINATE THE CARPET IF YOU USE TOO MUCH. (seprate the carpet backing from the fiber) Solvents will desolve glue.
