Propylene glycol is a substance that is commonly found in cosmetics, hair products, automotive products, paint and paint removers. This substance causes irritations to skin and has been reported to be responsible for kidney and liver damage when ingested. It is also an irritant to eyes. With these kinds of dangers, it is imperative to wear safety gear, such as goggles and gloves, when handling this chemical. When it is spilled on carpet, it is quick and easy to get out of the carpet, but you still must wear safety equipment to avoid skin irritations.
Put on the latex or rubber gloves and the safety goggles for protection.
Put 3 to 5 drops of heavy duty liquid dish detergent onto the propylene glycol spill on the carpet and spray the area with the warm water.
Allow the solution to sit for 5 minutes.
Scrub the area with the scrub brush.
Blot up as much liquid as possible with the paper towels.
Put a layer of paper towels over the spill, place the plastic bag on top of the paper towels and lay the book on top to secure the paper towels. The plastic bag provides protection for the book so that the book doesn't get wet.
Let the book sit overnight so the paper towels can absorb the rest of the liquid. Remove in the morning.
