There are two methods of de-rusting.

• Spray method: apply the product to the rust. Let the product soak in well. Work the surface with a hard scouring pad. Then repeat this treatment again until the rust is removed.
• Dipping method: Remove loose rust, dirt, grease and oil beforehand. Then pour SUPER De-ruster Xstrong into an artificial eye container or bucket (if the preliminary work does not fit into a container, use a brush). Immerse the object in the bath. Period of at least 15 to 48 hours depending on the rust layer. Remove the object from the bath regularly and brush off loose rust. This promotes performance. When the object is rust-free, wipe with a dry cloth, this will create a rust-preventing phosphate layer. Rinsing with water is also possible.
