"Remember that whatever product you use will be dependant on what the stain is. Some products are better for certain stains than others, and if you try a multitude of incorrect products, you will only cause bigger problems"
- From my neighbour who was a household carpet and upholstery cleaning specialist for a number of years
If you just want foam cleaner, scotch guard in the automotive section of walmart. It worked better then the dang steamer I rented to do my truck. Spray it on the stain the blot it out.
A couple of ounces of Woolite in a bucket of warm water, agitate with a brush and that solution, then extract with a shop vac, spray warm clean water from a spray bottle and extract that. Done.
