We had a mini-disaster when flushing radiators. The hose slipped off the drain cock and water covered about a square metre of carpet (about 80% wool) before we stopped the flow. This was well into the flushing process so the water was clean and the carpet has dried with little or no staining. However, I am worried about the underlay. Should we lift the carpet to dry that as well or is it best to leave well alone? The carpet was professionally fitted about 3 years ago and the underlay is called "Cirrus" which is a felt-like material.
