A commercial rust treatment

Summary

Describes experience with this commercial rust treatment product.

Method

Full instructions are on the tub.


Deox is a wallpaper paste-like substance made by Bilt Hamber Laboratories that comes in 1kg tubs. Start by removing loose rust with wire brush (use brass-bristle brush if delicate item). Deox is then applied by brush or roller in a thick layer and left for 30 mins/one hour. It's important not to let it dry out; cling-film can be used to prevent drying. Agitate surface with stiff paint brush to work in the Deox.

Wash off with water, and repeat if necessary. I took four applications to de-rust a badly rusted infill plane. Finally dry and apply protective coating (or it will rust quickly).

The treatment leaves the surface looking very clean/pickled, almost new looking; but tones down with time. It has the advantage of being able to be selectively applied to the steel part of a multi-substance item.

Deox is also available as a powder, to be dissolved in water, for dipping an item. I have no experience of this but it may be a less messy option than the paste.

The following pictures show treated and untreated areas on an old plane.
