5. Warm water and vinegar can effectively remove the stain inside the shower. What we need to do is to mix half-cup of vinegar and a gallon of water. This solution will soften the stains, and it can be wiped off or rinsed later on to ensure that the stain is removed. However, we need to remember that vinegar acts as an acid for marbles, and any marble tile might be destroyed after this cleaning process.

6. Use citrus fruits in cleaning the shower. There has been a long withstanding myth across Asia about the whitening power of citrus fruits like lemon. Many people from this region are using lemon to remove the stains on the shower, and as a bonus, the foul smell would also go away when lemon is used for cleaning.

7. If there are no lemon or citrus fruits available, we can go to a home improvement depot and ask for a cleaning agent that is infused with citrus fruits. These are effective in removing the stains inside the bathroom while filling it with the fragrant aroma from the fruits.
