Use Cocacola to clean the toilet
Step 1: Use a can of coca or a cup of coca water into a spiraling top-down toilet to allow water to flow through the yellow stains.
Step 2: When you have poured coca into the toilet bowl, wait at least 1 hour. During this time the acid content for coca water will make the plaque easily cleaned.
Step 3: Brush the toilet as you would normally using a clean brush to clean your family's toilet.
Use white vinegar and baking soda
If you don't want to use coca, use white vinegar and banking soda poured into the toilet and soak for an hour. After that, you will use a brush and scrub as usual to see a clean toilet.
Use fresh lemon
There are no acids in the composition of fresh lemon to help cleanse effectively. You mix lemon juice with detergent then pour the mixture into the toilet bowl, or the device has yellow stain soaked for 20 minutes or more. Next you use a scrubbing brush to stain the yellow stains that will quickly return you to the beauty of your family's toilet.
Use alum and lemon
If you do not want to use the above measures, you can use alum and lemon to create one, a mixture of alum and lemon is also a good way to help clean the shiny toilet suddenly.
You only need to put this solution into the sponge soaked in the solution and then wipe it several times on the surface containing the stain then leave it for 20-30 minutes to see the difference of this magic mixture.
