Unfortunately the very thing we use to clean with can be one of the most difficult things to remove from our carpet. Soap, when diluted, can be very effective in cleaning, but all by itself it can create a mess that's hard to rival. Cleaning soap out of a carpet is a tedious task that unfortunately offers no short cuts.
Wipe up as much of the soap as possible with a clean dry towel.
Use a damp cloth to wipe up more of the soap.
Pour a small amount of warm water onto the soap and wipe and blot up the bubbles.
Repeat this process of pouring water and blotting until there are no more bubbles.
Allow the carpet to dry. Setting a fan nearby may help to speed up the process.
Dry vacuum the area once the carpet is no longer wet.
