Clean rusty surface by Hard / Metal brush, If Possible.

Use protective gloves, long sleeves, pants and safety glasses before opening the can of Rust Stain Remover SAFE JELLY.

Apply the viscous jelly to the rusty surface by paintbrush until the entire object is coated with the jelly. Then keep Rust Stain Remover SAFE JELLY to react with rust for 10 - 20 Minutes time.

Again use hard brush / steel wool on rusted areas to remove the rust. The rust will easily come off as you scrub. If the rust does not come off easily, allow the Rust Stain Remover SAFE JELLY to sit for five additional minutes.

Finally rinse or flush  the entire rusted area with tap water.

Then to protect from further rusting neutralize the surface by use of RXSOL Alkaline Passivator  RXSOL-19-1521-050 onto the surface of the metal object until it is coated.

Scrub the surface of the object with a scrub brush and rinse with water from a garden hose. The RXSOL-19-1521-050 neutralizes the acid and stops it from continuing to act on the metal. Allow the metal object to air dry.
