How do I clean stains from rice pilaf from my off-white carpet and wall?
The method of cleaning will depend on what your carpet is made of.  Synthetic carpet (nylon)  -   and wool or wool blend carpet generally require different chemicals.  Wool responds well to slightly acidic condition based cleaners - a home made one being - approx 300mls (1 and a bit cups) of warm water, 1 teaspoon white vinegar and 1 drop of dish washing detergent.  mix well and dab on stain. Treating stain whilst still damp gives better chance of removal than when stain has dried out. Apply on a small patch of inconspicuos area first.  Dab dry with a towel.I worked as a wool technologist for 20 years and this was the most useful general method we used.
