Something that seems as simple as cleaning the bathtub can sometimes look tedious and complicated. This is because, with constant use, dirt penetrates and becomes more difficult to remove. In addition, water can bring lime, iron or other minerals that are harmful to the bathtub. In this post, we tell you how to deep clean your bathtub effectively and make it shine again.

First, it is important to identify what material you are dealing with before choosing the best method of how to clean the bathtub. Thus, you do not risk damaging the material. The most common types of bathtubs are porcelain, acrylic, enamel and fibreglass. Cleaning recommendations vary depending on the material. For example:

  1. Porcelain: in addition to being more durable, porcelain bathtubs are extremely resistant. They can be cleaned with a wider range of products, including commercial chlorine products.
  2. Acrylic: Acrylic is very similar to plastic and can be deformed or scratch easily. Therefore, avoid the use of abrasive cleaning materials such as pumice stone or steel sponges.
  3. Enamel: enamelled bathtubs are less common and require more care. No product with bleach or caustic soda should be used in this material so that it does not rust or become permanently stained.
  4. Fibreglass: fibreglass bathtubs are also delicate, and abrasive products should be avoided.

Step 1: Remove everything from the bathtub

Before cleaning, remove all personal care products, shampoo bottles, etc. You don’t want them to mix with any cleaning products. In addition, this is a great time to dispose of anything that you dont use, broken, or that will no longer be used.

Step 2: Clean the tiles and the walls around the bathtub

If the grout is moldy and dirty, use a tile cleaner and a grout brush. To do this, use the grout brush to remove the molds and dirt, work from top to bottom, then rinse any residue from the tile cleaner. Use a general-purpose cleaner or one that is formulated for the bathtub environment to spray down the walls. Thoroughly clean the walls, paying special attention to any dirty or sticky area. Remember to open the windows for air to flow freely, or use a fan if you are cleaning with a bleach-based cleaner.

Step 3: Getting rid of soap scum

However, look out for other places where it may form. The soap scum may be dark in color or may appear as a build-up in the bathtub. Take your time and clean it carefully.

Step 4: Clean the drain
