Rust Off®

What is Rust Off?

Rust Off rust and oxide film remover restores metal to a ready-to-coat surface. This convenient gel formula (easily mixed with water) makes quick work of removing rust and film. Rust Off should be diluted at a rate of 1 quart per 5-gallon bucket with water and applied at a rate of 400-500 square feet per gallon.

If it is gelled in the container, Rust Off can most likely still be used. Try mixing in warm water to aid in returning Rust Off to solution form.

How long should I leave Rust Off on metal surfaces before removing?

Rust Off is a concentrate. First mix one part Rust Off with 20 parts water (1 quart of Rust Off per 5-gallon bucket of water). Rust Off contains acid, so please ensure that the proper personal protective equipment (PPE) is being worn. Apply liberally with a brush or a rag.  

Rust Off takes about 10 minutes to work, and all scrubbing and power rinsing of the substrate should occur before the material has dried.   

Make sure to check all codes and disposal requirements in your area with regard to capturing the mixture that is being rinsed off the roof.
