When it comes to removing stains from a carpet, taking fast action is one of the biggest keys to success. As a general rule, it’s best to clean the carpet while the freshly spilled substance is still wet. This way it hasn’t had time to fully absorb into the fibers and carpet bed. However, the removal process does take a little know-how. Be aware that the wrong cleaning solution can make matters worse. It can set the stain, making it tougher to remove later on. In some cases you may even damage or destroy the carpet. If you’re unsure, it might be a good idea to consult a carpet cleaning professional as they may be better equipped to identify the stain and properly diagnose the right cleaning method. Meanwhile, there’s a little science to carpet stain removal. Here is our general overview.
The Basic Method for Removing Stains:
So Larry’s retirement party was a laugh riot- that is, until the final toast of the evening when the cherry-apple punch bowl was hip-checked and slid off the table. What to do?! First, identify the spilled substance, then get a wet paper towel or cloth. Blot the stain. Do not scrub back and forth. The idea is to transfer the substance from the carpet back onto the wet cloth. This is done with repeated compression, or dabbing. Not a back and forth friction, which only makes matters worse. Continue blotting until the spill is dry.
Next, choose your cleaning agent. See our Carpet Stain Removal chart below. If possible, it’s always a good idea to do a test patch cleaning first. Test a location such as underneath a sofa or other area where the carpet is rarely seen/exposed.
Spray the cleaning agent onto a fresh, wet cloth. Work from the outer edge of the stain first, moving toward the center. Continue to blot. Use light amounts of cleaning agent at first, and gradually increase if needed. Sometimes numerous attempts are necessary. Another fresh, wet cloth, with cleaning agent applied. Continued blotting until no more color transfer is seen.

When the stain is removed, flush it a final time with water. Squeeze out a fully wet cloth or use a spray bottle. Then blot for a final time. This will remove the cleaning agent. If possible, place a fan beside the stain to move the air and speed up drying.
