USE:

An effective all-purpose brush-on, wash-off cleaner, brightener, and paint preparation for all aluminum surfaces. Will clean and remove light oil, natural oxides, weathering stains, and light corrosion while etching to provide a firm primer bond. Restores new aluminum appearance. Concentrated solution - dilute before using.

INSTRUCTIONS:

ALUMINUM SURFACES: Surfaces heavily coated with oil, dirt, or mud should be cleaned with 1 part 310 Alkaline Cleaner in 20 parts water. After alkaline cleaning, mask any adjacent areas which may be damaged by acid contact, using cloth masking tape and polyethylene plastic sheet.

Dilute 1 part Aluma-Dyne E-2310 with 2 parts clean water using a plastic, porcelain, or stainless steel container.

Using rubber gloves and eye shield, apply the diluted solution with a nylon or polyester brush or synthetic sponge, working a limited area to provide adequate attention. Continue wiping the surface, especially vertical and bottom areas, to replenish drained off or spent solution. Horizontal surfaces which allow solution to "pool" will require less reapplication. Keep the surface wet for 1 to 5 minutes, depending on the surface position and the degree of cleaning, etching, or brightening action required. Excessively oxidized, stained, corroded, or pitted surfaces should be scrubbed with Scotch-Brite ultrafine cleaning pads while etching.

While the surface is wet with E-2310 solution, rinse with clean running water while wiping with clean rags or sponge. Do not rinse with hot water. Any acid remaining around rivet heads or seams can cause primer failure. Air blow hinges, seams, or joints which may trap acid.

Allow surface to dry, or wipe dry with clean rags and proceed with next operation within 8 hours. We recommend Aluma-Dyne E-2300 chromic acid treatment for corrosion resistance whether the surface will remain bare, be waxed, or painted with a clear or opaque finish.
