Add regular Coca-Cola, grate a bar of soap and have this homemade trick ready

Make your own cleaning mixture:

Grate a bar of soap (e.g., hard soap or household soap).

Add Coca-Cola – just enough to make a paste-like mixture.

Apply with a sponge or rag – e.g., to the oven, toilet, or rusty areas.

Allow to work briefly, then wipe off and rinse with clean water.

Caution:
Do not test on delicate surfaces, such as marble or aluminum – cola can damage them.

Do not use on electronic devices or textiles.
