Application Procedure

  1. To assure best results, the parts to be treated should be thoroughly cleaned to remove dirt, oils, and grease with an appropriate cleaning solution prior to treatment with Rust+Rescue™200. If thorough cleaning is not possible during use in the field, wipe the surface free of dirt and oils prior to application. All equipment, mixers, applicators or pumps should be clean and dry prior to use.
  2. Prior to use, mix thoroughly by shaking or stirring. Apply a light coat of Rust+Rescue™200 to the surface to be protected with a clean soft cloth, sprayer, brush or roller. Coverage is approximately 300 square feet per gallon. Wait approximately 10 minutes and then wipe off the excess product. Allow the surface to dry completely in air. Drying can be accelerated by use of a hot air oven or other drying medium such as an air blower (hair dryer).
  3. If rust is on the surface, remove all rust first with a rust remover such as CitriSurf®77plus or CitriSurf®2310, using the procedure recommended for that product. Then allow surface to dry completely before applying Rust+Rescue™200.

Notes on Use

Although very safe in normal use, Rust+Rescue™200 is a Calcium sulfonate based material, and as such it may cause
irritation to exposed surfaces of the body for some persons. See Material Safety Data Sheet before using this material. Rubber or plastic gloves should be worn to apply the product to the surface or to wipe it dry.


Dispose of according to all federal, state and local regulations.


Rust+Rescue™200 should be stored at temperatures between 10 °C and 49 °C in steel or approved plastic containers (polyethylene or polypropylene).
