Soap stains often remain on plumbing fixtures and over time yellow stains may appear.
Regular detergents are unlikely to help us, especially when it comes to stubborn stains.
In this case, it is worth paying attention to methods that have been tested over the years.
This is an ideal product for bleaching even a completely yellow bathtub. It is easy to use. First, take the required amount of soda. Keep in mind that it should be enough to cover all yellow areas. Combine it with a small amount of liquid, bringing it to the state of a paste.
Spread on the stains and wait 15 minutes.
Next, in a container with a spray bottle, combine water and citric acid so that the crystals are completely dissolved. Apply the mixture to the soda.
Wait another 10 minutes and rub off the stains.
It is worth warning that when working with ammonia, it is imperative to use a respirator. Pour 200 ml of water into a container with a spray and add three large spoons of ammonia.
Wait 15 minutes. Then rub the stains with a sponge and rinse the bathtub with water.
