DO not use CLR on natural stone or marble, terrazzo, colored grout, painted or metallic glazed surfaces, plastic laminates, Formica, aluminum, steam irons, leaded crystal, refinished tubs or any damaged or cracked surface. CLR may etch older sinks, tubs and tiles. CLR is corrosive. Avoid contact with wood, clothing, wallpaper and carpeting. Some laminated surfaces (counter tops) are coated with a synthetic surface which may be affected by rust removers; clean spills immediately.

CLR (Calcium, Lime, and Rust Remover) is a cleaning product that is designed to remove calcium, lime, and rust deposits from a variety of surfaces, including aluminum. It works by using a combination of powerful acids and surfactants to break down and dissolve the deposits, making them easier to remove.

To use CLR on aluminum, you will need to follow the instructions on the product label. In general, you will need to apply the CLR to the affected area, allow it to sit for a few minutes to allow the chemicals to work, and then scrub the area with a scrub brush or a scouring pad to remove the deposits. You may need to repeat the process if the deposits are particularly stubborn.

It is important to use caution when using CLR on aluminum, as the chemicals in the product can be corrosive and may damage the surface if not used properly. Be sure to wear protective gloves and goggles when using CLR, and follow all safety guidelines on the product label.
