Caustic Cleaners for Paint Removal

Types of Caustic Cleaners

• Not only are there many types of caustic cleaners, but also many similar products work with the same efficiency. There are commercial products made for stripping, but also there are household products that have the same chemical composition and will do the same job at a lower cost. For example, many model hobbyists use Mr. Muscle oven cleaner to strip model paint instead of the more expensive Chameleon Model Stripper solution. According to Encyclopedia.com, caustic cleaners are "able to burn or corrode organic tissue by chemical action." Some types of cleaners are oven cleaner, caustic soda, brake fluid, varnish remover, lighter fluid and Chameleon Model Stripper are just a small sampling of the different stripping solutions available.

Surfaces

• The type of surface to be stripped is what determines the caustic cleaner to be used. Enamel paint on old airplane models needs a different strength of cleaner than a single coat of paint on wood surfaces. The size of the item also is important. Stripping a dresser or large table requires a cleaner that can be painted onto the surface. A small model can be sprayed and put in a plastic bag to allow for the cleaner to work. Solvents can be used on the hulls of ships, airplanes, models and wood furniture to name just a few surfaces. According to the EPA, "the composition of the object to be stripped may limit the kinds of the stripping technology that can be used as well."

Stripping Alternatives

• There are many alternatives to using caustic chemicals. The Environmental Protection Agency's suggestion is to “Consider Mechanical Methods.” Using a wire brush or other abrasive material to rub off the paint. Other methods include tumbling the item with stones, blasting with non-toxic media or wheat starch and using sodium bicarbonate. The University of Minnesota Technical Assistance Program has more information on "safer stripping and cleaning chemicals." (See Resources). The local hardware store is also a great resource for paint stripping information.

Safety Precautions

• Caustic cleaners can burn skin and have toxic fumes. Always use these cleaners in a well ventilated area and follow all manufacturers directions. Wearing rubber gloves and eye protection is also recommended.
