2. FEATURES

  • Excellent wetting capacity on both ferrous and non-ferrous metals.

  • Contains an inhibitor to reduce the attack of the metal surface and to prevent the formation of hydrogen.

  • Economical concentrate.

  • Can be diluted with water to any concentration needed (see Directions for detailed information).

  • Specifications : meets the performance requirements of Mil-C-10578 (type III).

3. APPLICATIONS

  • Rust and scale removal from :

ferrous metals

non-ferrous metals

  • Oxidation and stains removal from :

aluminium

copper

brass, ...

  • Metals preparation prior to painting

  • Cleaning of :

in-process parts and assemblies

sheet metal

  • Restoration of rusted parts

  • Removal of metal and rust stains from porous materials.

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.

  • A safety data sheet according EU directive 93/112 is available for all CRC products.
