If you need to use a lot of water to get the stain out, put a bin bag under the rug, first, so it doesn’t soak through to your floor or carpet. To dry your rug (only once the stain is out, don’t dry it before cleaning it as the stain will set), fold a large towel, place it 4 layers thick on the wet patch, and stand on it for a minute, shifting your weight around to cover the towel. This will draw the water into the towel. Repeat with dry towels.
Since having Darwin I’ve cleaned a lot of carpets and rugs
