The key to clean toilets is to have a toilet that can actually be cleaned after it becomes dirty.
I’m not trying to gross you out, but the picture below is the underside of a clean toilet seat (although it doesn’t look clean). No amount of scrubbing or bleach will get this any cleaner looking because the paint itself has become etched and stained.
In addition, these screws (see arrows) will rust over time, and then little bits of rust that looks like black grit will fall onto the toilet rim. You can wipe it up all you want, but the problem will continue because the screws will continue to rust.
The solution is really simple, you need to install a plastic toilet seat!
Plastic seats are actually usually cheaper than the molded wood ones – I guess because they are “less fancy,” but they will not become discolored with use!
Just be sure to buy the correct size seat – toilet bowls are either round or elongated. Most newer toilets are elongated, but some older homes and/or smaller bathrooms have round toilet seats.
And there are no screws to rust onto the toilet bowl!
Installing a new toilet seat is a 10 minute job – tops. It is super easy, inexpensive, and you will be so glad you did when it is bathroom cleaning day and you can actually get it shiny and white like the it was the first day you bought it!
