My carpet is 8 yrs old. Its dirty, I already hired some professional carpet cleaners but the dirty color is still there. It was a Cream color before, now its like brown-ish or something like that. Any suggestions? I do not want to buy new carpet, I dont have the money for that right now.

I cleaned my carpet recently and used the required amount of shampoo in my carpet cleaner, but it left residue on the carpet. Now the carpet feels dirty/sticky-ish. Is there any way to get the residue out of the carpet so that it feels soft again? I’ve already tried to go over the area with water instead of a shampoo/water mixture….it didn’t work.
