How to Remove Rust Stains From Porcelain Sink

Porcelain sinks are a popular choice for many homeowners due to their durability and classic aesthetic appeal. However, over time, these sinks can develop unsightly rust stains, which can be quite challenging to remove. If you have been struggling with rust stains on your porcelain sink, here are some effective methods to help you restore its pristine appearance.

1. Use Lemon Juice and Baking Soda
One of the easiest and most natural ways to remove rust stains from a porcelain sink is by using lemon juice and baking soda. First, squeeze the juice of one lemon onto the stained area and let it sit for 10-15 minutes. Then, sprinkle baking soda over the lemon juice and gently scrub the stain using a soft cloth or sponge. Rinse the sink with water, and you should notice a significant improvement in the rust stain.
