Just so you know, Comet will not scratch the porcelin in the bowl.
Remember there is water (clean I hope
) in the bowl when you
sprinkle the comet in therefore later when you scurb it is mixing
with the water therefore preventing scratching. I swear this works
wonder's. I used it for years in my home and put 2 new bathrooms
in the Condo when I moved in. It's been 10yrs and not a single
mark in my bowls
Remember when you sprinkle it in the bowl
to make sure you get it on the sides not just in the water.
