Specialist Liquid Rust Remover 300042

This WD-40 Specialist liquid removes rust from aluminum and steel surfaces. The water-based formula comes ready to use in a one-gallon jug. It produces no toxic fumes, is acid free and non-irritating to skin. The product is non-flammable with zero VOC content and carries an NSF P1 rating.

Who should use this rust remover

Maintenance teams and workshops needing a non-flammable, acid-free solution for steel and aluminum parts will find this suitable. The liquid requires rinsing after application and has a slight fragrance. Buyers needing a no-rinse formula or a product approved for other metals should look elsewhere.

One-gallon ready-to-use liquid format

The remover is supplied as a one-gallon jug of ready-to-use liquid. This volume suits bench-top immersion or repeated spray-and-wipe jobs without dilution. Users who need a smaller container, an aerosol, or a concentrate to mix on site will need a different product.

Questions about this item

Should I pick the one-gallon jug or is there a smaller size for a quick job?

The product is offered only as a one-gallon jug, so that is the version you receive.

How does the rust remover perform once I pour it onto a corroded steel part?

The water-based liquid dissolves rust on steel and aluminum without toxic fumes, though a rinse is required after use.

Does the NSF P1 rating limit where I can apply this in a food-processing area?

NSF P1 means the formula is approved for incidental food contact, so it can be used on equipment in and around food zones.
