Has your bathtub turned yellow? Don't worry: you can easily restore the tank to its clean, snow-white state.
And it is not at all necessary to use household chemicals.
There is one natural remedy that will do the job better than any powder or gel.

So, a fruit that is most likely in your refrigerator will help you perfectly clean your bathtub.
We are talking about… lemon. The juice of this particular citrus fruit is an ideal cleaning agent.
How to Clean a Bathtub with Lemon
First, prepare some small container: you will need to squeeze the citrus juice into it.
Next, apply the resulting liquid to the inner surface of the plumbing fixture.
Use a sponge for this. However, there is a more interesting option: use half a lemon from which the juice was squeezed.
After completing the procedure, set a timer for 15 minutes. During this time, the citric acid will have time to dissolve the dirt.
Once the time is up, go over the inside of the tub with a clean sponge.
After this, rinse the tank with a shower head. Important: the water used should not be cold or very hot. It is important that the liquid is warm.
The final stage: wiping the bathtub with a clean, dry cloth.
The result is perfect snow-whiteness. Not a single spot will remain. The surface will shine.
