How to remove scale rings that formed around the outside of all the rim holes?
It's a rental house american standard, plain white 'regular' finish toilet. It's still in great condition and flushes well. It was kept clean in general but nothing was done to remove the hard water line and scale rings that formed around the rim holes.
I reamed out the rim holes (not much in there), then ran my pond pump in the bowl and down the overflow tube with a gallon of vinegar for a few hours. This softened a lot of the scale around the rim holes and the water line, I was able to brush away a good bit of it.
Next I buffed the inside of the bowl using a cordless drill with a 2" sanding disk pad affixed with a piece of "wall sand" sanding netting. In just a few minutes the water line ring and 'rivulets' of mineral deposits below the rim holes were gone, the bowl is shiny again and feels smooth to the touch.
This leaves me with removing mineral coating in the 'throat' that I couldn't reach with the sanding pad, and also removing the rings of crusty scale circling the rim holes.
Have you got any tips for cleaning and polishing up these last areas, especially the scale around the rim holes?
