3M Marine Aluminum Restorer and Polish 18 oz Tube — Concentrated Oxidation Remover & Brightening Polish

3M Marine Aluminum Restorer and Polish 09020 is a concentrated aluminum cleaner and polish that removes heavy oxidation and restores a bright, weathered finish on marine and exterior aluminum surfaces.

Designed for professionals and experienced DIYers working on boats, trailers, signage, and other outdoor aluminum, this 18 oz tube combines cleaning and polishing in one product. The thick, concentrated formula dissolves chalking and oxidation, then polishes the metal to reveal the original luster. It can be applied by hand or with a machine polisher, making it versatile for small touch-ups or larger restorations.

How does this product remove heavy oxidation and chalking?

The formulation contains abrasive and chemical cleaning agents that break down oxidation and lift chalky residue from aluminum surfaces. When worked into the surface, it abrades away the degraded layer and polishes underlying metal to a smoother, brighter finish.

• Concentrated formula for effective removal with minimal product
• Works on thick chalking as well as lighter weathering
• Can be used manually or with a rotary/buffer tool

Will this polish work on all exterior aluminum pieces?

It’s formulated for marine and industrial aluminum exposed to weathering, such as hulls, decks, trim, and trailers. Avoid use on painted, anodized, or non-aluminum metals unless compatibility is confirmed.

• Best for bare, weathered aluminum surfaces
• Not recommended for painted or anodized finishes without testing
• Safe for common marine aluminum alloys when used per instructions

How should I apply the 18 oz tube for best results?

Apply a small amount to a clean, dry surface and work it in using a cloth, pad, or machine polisher. For heavy oxidation use moderate pressure and repeat passes; finish with a clean buffing cloth to bring out shine.

• Use sparingly — concentrated formula covers a lot
• Apply by hand for small areas; use a polisher for large jobs
• Wipe off residue and buff to a consistent shine

Are there safety or usage restrictions I need to know?

This product is intended for industrial/occupational use; follow safety data sheet directions and use protective gloves and eye protection. Avoid inhaling dust or vapors from machine buffing and keep away from children and pets.

• Use in well-ventilated areas and with appropriate PPE
• Follow instructions for machine polishing to prevent surface damage
• Not marketed for consumer household use—intended for professional settings
