        4. DIRECTIONS

        • 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.

           

        Heating (up to 65°C max.), agitation or wiping will speed up cleaning action.

        • 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.

        • Equipment used must be made of acid resisting material such as stainless steel, wood, rubber, plastic, glass or ceramic.
