I put a cast iron pan in my porcelain sink overnight, intending to clean it in the morning.
The next day, I found a huge rust ring under my pan. Horrors!!
I scrubbed it with Soft Scrub with bleach. The rust ring remained. Horrors!!
After I finished bemoaning my terrible luck – and wondering how much it would cost to replace my sink – I googled to see if I could find a less-drastic solution to a terrible, terrible mistake.
Several sites recommended an unconventional (at least in my mind) solution – scrubbing the sink with a pumice stone.
Simply wet the stone and scrub scrub scrub. The stone will release fine particles. Don’t panic when it does this – it’s normal.
You’ll have to scrub a.lot.
What a relief!!
Note: You should always test out a rockin’ awesome solution like this in an inconspicuous spot of sink just to be safe.
