Heavy rust and scale (ferrous metals) : dilute concentrate with 3 parts water. Metal should be immersed 20 minutes to 1 hour. Remove and rinse metal with water and treat immediately with CRC 3-36 for water displacement and corrosion protection.
Heavy corrosion (non-ferrous) : dilute concentrate with 7 to 10 parts water. Metal should be immersed 20 minutes to 1 hour. Periodically check non-ferrous metals. Remove and rinse with water. Treat immediately with CRC 3-36 for water displacement and corrosion protection.
As a metal cleaner (ferrous and non-ferrous) : dilute concentrate with 15 to 20 parts water. Metal may be immersed, brushed or wiped until the desired brightness is obtained. Rinse with water and treat immediately with CRC 3-36 for water displacement and corrosion protection.
Quicker results are obtained by prior removal of oil and grease, using CRC Industrial Degreaser or CRC Fast Dry Degreaser.
CRC Rust Remover is mildly acidic; therefore, reasonable care should be taken. Rubber gloves and protective goggles are recommended.
