How to Use CLR Cleaner in a Rusty Sink

Calcium lime rust is a rust remover created for use in kitchens and bathrooms. CLR is manufactured by Jelmar and has the power to eliminate any rust that has formed on your sinks. Homeowners must use CLR according to the packaging instructions, however, as calcium lime rust is corrosive, containing citric, lactic, sulfamic and glycolic acids.
