Wear rubber gloves resistant to chemicals to protect yourself from skin irritation caused by the glycol. Absorb as much of the glycol from the carpet with a disposable cloth. Blot gently without applying pressure.
Use a wet/dry vacuum to suck up the excess glycol from the carpeting. If the liquid has penetrated into the backing, pull the area of the carpet back, and remove the glycol from the backing.
Add 3 to 4 drops of clear dish soap to the stain, and mist the area with water. Scrub the carpet with a soft-bristled scrub brush.
Rinse the soapy liquid out of the carpet with the wet/dry vacuum. Then, place a stack of paper towels on the carpet. Set a heavy book on top of the paper towels, and let the area dry for several hours.
