New to the forum however i have viewed topics several times. We installed two Drake 2 toilets with the tornado flush and they really are easy to clean with the fancy finish on them, However i have water stains in the two inlets where the water goes into the bowl during the flush cycle. Wondering the easiest and best method to clean the porcelain inlets and how far the tubes can be cleaned ? I am guessing a brush of some sort that would not damage the porcelan is the solution but thought i would ask here first before i go and damage something. Hoping i can find the answers here by someone who has dealt with the problem. Thanks for any info you can provide.
