Soaking in a bathtub is one way to destress from a long day. Whether you enjoy the bathtub every day or occasionally, keeping it clean can keep your bath fresh. So, what should you use to clean your bathtub? Does baking soda clean bathtubs?

Yes, you can clean your bathtub with baking soda. Baking soda is known as a “scratchless” abrasive cleaner suitable for most surfaces. It removes dirt, stains, and foul odors and brightens surfaces.

Can Baking Soda Clean Bathtubs?

Absolutely! Baking soda is sodium bicarbonate. Beyond making your baked goods light and fluffy, it is also an alkaline cleaner. Once put in a dirty bathtub, it will react with stains to create glycerol, a natural cleansing agent found in soaps

Also, when baking soda mixes with vinegar, the mixture will release carbon dioxide to form acid or a weak alkali. The result will make the bathtub even brighter and eliminate foul odor.

Why Do Bathtubs Have Dark Stains?

Knowing how stains form in your tub will help ease your dirty bathtub problem. The bathtub or shower, in general, is vulnerable to dark stains.

These stains come from dissolved minerals or iron in your water that react with oxygen. When they settle on your tub, stains will form.

Fortunately, these stains are not hard to remove. Keeping a cleaning schedule will help eliminate them. And using baking soda will also help because it’s a natural alkaline cleaner.

How Often Should a Bathtub Be Cleaned?

Clean your bathtub every week, and deep clean it monthly. When you clean weekly or monthly, household staples like baking soda, vinegar, and lemon will do the trick.

However, if you wait longer than that you may need a stronger cleaning product like Miracle II Soap or Sal Suds.
