Frequently asked questions

What causes the hard water stains on the porcelain sink?

The minerals in hard water are what are responsible for stains on a porcelain sink. Some tend to get nasty over time so it is better to clean as soon as you notice them forming and make a regular cleaning habit of removing the stains. Hard water contains minerals such as copper and magnesium.

How does one remove hard water stains from a porcelain sink?

To remove rust stains from plastic bathtubs, focus on products that contain natural acids. Vinegar contains acetic acid, cream of tartar contains tartaric acid, and lemon juice is rich in citric acid.

Bar Keepers Friend is another good choice because it’s a product that contains oxalic acid. Instead of going for bleach, these products will solve your hard water stain problem.

Is bleach suitable for removing hard water stains from porcelain sink?

No, bleach will not remove the hard water or rust stains on your porcelain sink. Bleach will also eat away at the material on your sink and over time, lower the quality. Bleach can be very toxic, especially when mixed with other ingredients. So why insist on bleach when simple natural products can get the job done?
