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.

Questions and Answers

Q: Is RustBlast safe if it is gets on wiring, rubber, etc. during the process of using it on a car chassis?

Asked by:  - 1/2/2014

A: Yes, as long as the contact is casual and the RustBlast is rinsed off with water, RustBlast should not affect your wiring and rubber components.

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.

Asked by:  - 4/27/2015

A: RustBlast works very well on aluminum to etch the aluminum allowing excellent adhesion of paint.

Rating Seems to seal up the rust
I used this to help clean the exhaust headers on my truck, and also for the rust on the body. I've taken both the patience approach and the approach of wire brushing to kind of help things along. It does work albeit slowly. The film it leaves really does help with paint adhesion too
