We have mineral deposits inside toilet bowl ( below the marine line creeping from the pipe where on earth waist goes down.) tried lime a road, does not help, tried even mitt scrabing, deposit is too hard. Help. what can desolve it? It is getting worse near time.
My credit card go thru the laundry--will it...
Answers:    any hardware store should sell a fine, fine position of sandpaper specifically used to clean that out of toilets... it works better than puma stone...near puma stone, you have to pay attention not to hit a dry spot, if you do, it will scrape the porcelein sour...the sandpaper doesnt...hope that helps!
Swifer damp shot Vacuum?
shift to your local hardware store & ask for denatured alcohol . force water down the bowl to expose the lime deposit ring. pour the alcohol on a cloth & while using rubber gloves ... scrub the ring & it should disolve.
It's a mess! , will you please vote...
