Looking for the complete caravan awning setup and buying guide?

From choosing between air and poled awnings to setup tips, storm protection and seasonal advice, our Caravan Awnings UK – Complete Guide (2026) covers everything you need to know. It’s the perfect place to start whether you’re buying your first awning or upgrading your current setup.

Aluminium awning poles are designed to resist rust—but over time, they can develop surface corrosion, oxidation, and staining that looks like rust.

This is especially common if:

• Poles are stored damp

• Used near the coast

• Packed away without drying

• Exposed to road salt

The good news is this is easy to clean and restore.

What Causes “Rust” on Aluminium Poles?

Aluminium oxidises rather than rusting, creating:

• White powder residue

• Grey or black staining

• Light surface pitting

This is usually cosmetic but should still be cleaned.

What You’ll Need

• Warm water

• Mild detergent

• Soft cloth or sponge

• Soft brush

• White vinegar or aluminium cleaner

• Microfibre cloth

Optional:

• Non-abrasive pad

• Silicone spray
