Directions to use: 620-RR Heavier Rust Remover
- Pour Zerust® ICT®620-RR into a container with the rusted parts (fully cover parts).
- Soak the rusted parts in Zerust® ICT®620-RR for ~30 minutes for light rust and overnight for heavy, flaking rust. *DO NOT spray the rusty parts with ICT®620-RR—the product will not work this way.
- Rinse the parts with de-ionized water and inspect.
- Wipe parts with a dry cloth if needed (some black carbon residue may remain on the metal surface).
- Repeat soaking if rust remains, and re-rinse.
- Air dry. Check for areas where solution may have pooled, re-rinse and dry.
- Package parts in Zerust® products to prevent the recurrence of rust.
Note: When the active ingredients are used up, the Zerust ICT 620 bath will turn black and will not remove rust.
