Aluminium is used in a wide range of products, from cast-aluminium cookware to automobile parts. While aluminium resists rust, it may dull from everyday use and wear. Gray discolouration and a dull patina also can result from regular cleaning or exposure to weather.

You can revitalise and restore the lustre of cast aluminium without speciality cleaners by using minimal household supplies.

Put on rubber protective gloves.

Place 2 tbsp of distilled white vinegar and 1 quart of water in a plastic bucket.

Soak a sponge in the vinegar-water solution, and use the sponge to scrub the cast aluminium until the item is clean and you achieve the desired patina.

Rinse the cast aluminium thoroughly with clean water.

Dry the item completely. Use a cotton towel to prevent scratching polished surfaces.
