The interesting sense of relaxing in the bath while listening to melodious music may be your desire when deciding to install a bathtub in your bathroom. However, your bathtub becomes yellowish gradually despite your weekly or daily cleaning and scrubbing. Definitely, it is time for you to search for the best product to clean a bathtub to help you save your lovely bathtub’s cleanliness. Sparkling and Beyond will recommend some products that we are applying and instruct you on how to effectively use them. 

1. Why is my bathtub dirty?

The most common culprit of yellow stains on the surface of the bathtub is hard water which contains a lot of minerals that can build up in your bathtub. 

Besides, shampoo residue and dust, and other kinds of debris such as food, and trapping residue,… can also be a factor contributing to the dirt of the bathtub. 

There are many kinds of bathtub detergents that work at different levels to help you eliminate dirt. However, an indiscriminate selection of cleaners can lead to more hassle than a dirty bathtub, review some common detergents below to find out which one is suitable for your bathtub.

2. What kind of product should I use to clean my bathtub?

Depending on the features of the dirt and the material of the bathtub, you should choose which product is the most suitable for you. Our cleaning expert has investigated the case and recommended several cleaning products:

a. Organic bathtub cleaner

As the demand for cleaning the bathtub increases, many companies have produced bathtub cleaner solutions to help people do cleaning much more easily.

Instruction: Like other bathroom appliances which have their own detergent, a bathroom detergent is a preferable option since it has been studied and evaluated by scientists. However, remember to check the instructions carefully to find a suitable product for your bathroom.

Important: Scrubbing the porcelain with a sponge is better than using a brush since the brush can damage your porcelain. 


  • Easy to find in the grocery store
  • Non-toxic


  • Not compatible with all materials, must follow instructions of each type. 

b. Natural ingredients

  • Clean bathtub with vinegar and baking soda

The combination of baking soda and vinegar is an amazing compound that provides a strong cleaning power to eliminate even the hard and stubborn stains such as limescale and mineral buildups,… You can use vinegar or baking soda only to clean the bathtub, they still work if used separately. The acidity of these chemicals will help you to remove stains or visible dirt but also slightly corrode your bathtub. Mixing vinegar and baking soda will reduce the corrosion ability and increase the cleaning ability.   

Instruction: Spray vinegar onto the whole surface of the bathtub and sprinkle baking soda afterward. Leave the solution for at least 30 minutes to finish their mission. Then, scrub with a sponge and rise again with water.

A mixture of Borax Substitute and water and lemon juice or white vinegar creates an abrasive multi-purpose cleaner. It’s great for tackling mold, and general kitchen and bathroom cleaning.

Next, dip a sponge and begin scrubbing then rise again with water. This solution works also effectively in cleaning other bathroom appliances such as the shower head, and toilet bowl,…
