Method 1: How to Clean Brass with Baking Soda and Lemon
This method is ideal for quick cleaning and polishing brass without waiting too long for results.
Ingredients:
- 1 teaspoon baking soda
- 1 teaspoon lemon juice
Estimated Cleaning Time: 15 minutes
Steps:
- Combine the baking soda and lemon juice in a bowl. Mix until it forms a smooth paste.
- Using a soft cloth, apply the paste to the brass surface, ensuring an even coating.
- Let the paste sit for 10 minutes to work its magic.
- Gently rub the surface to remove tarnish, then rinse thoroughly with warm water.
- Dry the item with a clean, lint-free cloth.
Why It Works:
The lemon juice’s acidity dissolves tarnish and prevents green oxidation, while the gentle abrasiveness of baking soda polishes the surface without scratching. This method is perfect for restoring smaller brass items or fixtures quickly.
Method 2: How to Clean Brass with Lemon and Salt
For stubborn tarnish or larger brass pieces, this method provides a deep clean and long-lasting shine.
Ingredients:
- 2 tablespoons of table salt
- 2 tablespoons of lemon juice
Estimated Cleaning Time: 15 minutes
Steps:

- Rub the mixture or salted lemon directly onto the brass item, focusing on tarnished areas.
- Continue rubbing gently for 10 minutes, then rinse the brass with warm water.
- Dry with a soft, non-abrasive cloth.
Why It Works:
Lemon juice penetrates oxidation layers, while salt acts as a natural abrasive, polishing the surface to perfection. However, avoid scrubbing too hard, as excessive force may leave rub marks on the metal.

White vinegar is excellent for breaking down tarnish due to its acidic properties. The salt gently scrubs the metal without scratching, and the flour creates a cohesive paste for easy application.
