Aluminum reacts slightly with water and minerals, helping break down tough stains.

Its texture provides abrasion without scratching, unlike some brushes or steel wool.

It’s inexpensive, widely available, and can be reused multiple times.

Tips for Best Results

Use a fresh piece of foil for very stubborn stains.

Avoid overly aggressive scrubbing to protect the porcelain glaze.

Combine with regular cleaning to prevent stains from building up.

With this trick, a simple ball of aluminum foil becomes a surprisingly effective tool for a sparkling clean toilet — no harsh chemicals required!
