fastest way to clean toilet ring stains without chemicals

i tried cleaning hardened toilet ring stains with vinegar-baking soda combo and other harsh chemicals with no luck before.  this method is by far the fastest way to remove those nasties with minimal effort.

flush your toilet once or twice.  wear rubber gloves - or not.

squirt a generous amount of all-natural liquid dish soap.  this will serve as a buffer between the sandpaper and ceramic toilet bowl.

lightly scrub the hardened toilet ring stain with low-grit sandpaper.  this will only take approximately 2 minutes or less.

flush again.

done!  you could also use this method on yellowed, scaled faucet and sink!
