RustBlast - Remove Rust
RustBlast - Remove Rust

I buy and store old parts that are no longer available for future motorcycle restorations on bikes in my collection. To keep the parts from further deterioration before use, I remove the rust before putting them away for future use.

You can remove the rust with Rust Blast without removing any of the chrome that would happen with a destructive rust removal method like media blasting.

It only takes a little Rust Blast to clean a rusty rim. I add a few ounces of Rust Blast to a flexible disposable aluminum pan and shape it to fit the part. Spin the rim around in the Rust Blast for an hour and you have a rust free rim.

Every year the day after Thanksgiving, I go to the local chain grocery store and buy a shopping cart load of 75% off disposable aluminum pans of all sizes to clean parts.

Q: If I have new steel, do I have to let the RustBlast stay wet on the surface for the minimum of 30 minutes or can I do less time?

Asked by:  - 12/4/2014

A: New steel is usually very smooth, so we highly recommend leaving the surface wet with RustBlast for a minimum of 30 minutes so that you have an ideal surface profile when you go to apply the RustSeal. Also, remember to keep the surface temperature as warm as possible (within our temperature guidelines) because the warmer the RustBlast is, the more effective the RustBlast is.
