Did you know that in wet climates leaving the toilet seat shut actually ruins the toilet?

Mold creeps and grows
Beneath the porcelain stand
Festering with love
A nightmare in the bathroom

Spores invade our hearts
Decay in disguise
Choking life silently

Rot spreads inside
Toilet seat armada
Breeding ground for misery

Flesh-eating brand
Of fungal colony
Consuming grandma
In her nightly pee
Screams echo nada
As she's devoured with glee

I wouldn't say it ruins the toilet but it does encourage the growth of mold.

It puts black stripes that have to be scrubbed off with limeaway and metal. It happens when it rains but i do live im Wa state. Mold would be so much easier to clean off.

Hard water manganese that can attract mold as a top layer.
