CLR cleaner, also known as Calcium, Lime, and Rust Remover, is a household cleaning product used for dissolving stains such as calcium, lime, and iron oxide deposits. It is a heavy-duty cleaning product that requires some precautions when using it. Here are some key points to keep in mind when using CLR cleaner:

• CLR cleaner is effective on grime and build-up because it dissolves calcium, lime, and rust using ingredients for safer chemistry.

• CLR cleaner can be used on a variety of surfaces such as chrome, fiberglass, porcelain, and stainless steel appliance exteriors.

• CLR cleaner should not be used on wood, clothing, wallpaper, carpeting, natural stones, brass, copper, aluminum, galvanized metals, any painted, coated, or sealed surfaces.

• CLR cleaner should not be left on an area for longer than two minutes or mixed with other household cleaners or bleach.

• CLR cleaner should always be diluted with water. The ideal solution is one part CLR to one part water.

• CLR cleaner is acidic and can cause etching and damage to certain surfaces. Always spot test first and clean spills immediately to avoid damaging surfaces through inadvertent contact.

CLR cleaner is made by Jelmar LLC, an American company located in Skokie, Illinois, and contains ingredients such as water, lactic acid, and gluconic acid. It is part of the EPAs Safer Choice Program, recognizing the product as a safer alternative to traditional chemicals.
