Wool makes for a very beautiful piece of carpet. Wool is also extremely durable and resists packing better than most synthetic carpets. Wool carpet is also very expensive and difficult to clean.
Like most natural fibers, wool carpet cannot take a very high heat, nor can it take very high or low PH solutions. This limits the options carpet cleaning professionals have to address your cleaning needs. It is important to notify your cleaner if you have wool blended into your carpet or if it 100% wool.
If you think you may have wool carpet, but you are not sure you can ask your cleaner to do a burn test. Wool carpet will turn to ash while synthetics melt.
