Toilet seat stains will occur over time due to water rust stains, as well as other undesirable elements found around the toilet area. In order to avoid tough stains on the toilet seat, you need to regularly clean the commode on at least a weekly basis. Stains that are ingrained into the surface of the toilet seat may require a more aggressive approach, and there are some stains that you just cannot remove. But with a little elbow grease and patience, you just might be able to save that seat.
Remove the toilet seat using an appropriate-size screwdriver. This will make it easier to get to the stains and remove them all.
Use water and baking soda (or a powdered cleanser) to clean the toilet seat. The baking soda will form an abrasive paste that will work in conjunction with a scrub brush to remove the toilet seat stain.
If the baking soda paste does not remove the stain, utilise a large cleaning tub with bleach diluted with three parts water to one part bleach. Make sure the work area is adequately ventilated, use rubber gloves when handling bleach and rinse off any residual chemical cleaners with water thoroughly before submerging the toilet seat in bleach water. If you prefer, you may skip Step 2 and just do the bleach bath.
If you have a coloured toilet seat, apply a small amount of the bleach solution to an inconspicuous area to make sure the bleach solution will not ruin the finish of the toilet seat. Place the detached toilet seat in the bleach water solution for five to 10 minutes. Scrub the toilet seat with the scrub brush to remove the stains; repeat the soaking process as necessary, and rinse with water.
Reinstall the toilet seat to the commode with the screwdriver. Be careful not to over tighten the mounting screws, as this will cause damage to either the commode or the toilet seat.
Do not over scrub the toilet seat, as this may cause damage. Never mix cleaning chemicals together, as this can cause dangerous reactions.
