Yellow colors don’t necessarily mean that the toilet seat is dirty. However, none wants to use a stained toilet & we should know when to give up on cleaning & get a new one. 

To prevent these stains from appearing, we first need to know their causes. Let’s see then. 

1. Urine stains

The yellow stains on your toilet seats are most likely from urine. When urine comes in contact with water, ammonia salts break down into ammonium hydroxide, breaking down organic matter like bacteria, and fungi on the toilet seat. 

After some time, the toilet seat may develop yellow stains from high uric acid concentrations. Flush the toilet every time. Everyone should clean up the toilet seat and lid properly after every use.

2. Hard water

Hard water also causes yellow stains on toilet seats, and the reason behind this can be a build-up of calcium and other minerals that can accumulate over time on the toilet seat. To get rid of this, you can use fresh water.

3. Sun exposure

Open sunlight causing yellow stains is rare. Sunlight containing UV rays is responsible for sunburn on toilet seats that eventually turn the white color into yellow. So, to prevent sunburn, sunlight should not directly fall on your toilet seat.

4. Overtime

Using a toilet seat for a very long time can also cause yellow stains. So, changing a toilet seat after using it for many years is the only prevention.

5. Use of bleach

Sometimes, the use of bleach becomes the reason for yellow stains. Though bleach is a great disinfectant, it can discolor plastic toilet seats if the bleach is not a good one or in an undiluted state. So, trying a new brand or diluting it more before using it can be effective prevention.
