Go to the hardware store and get some muriatic (hydrochloric) acid. But ya got to be careful with it. A little goes a long ways. Do NOT use it on metal surfaces including the drain ring in your sink.
But for a skweeky clean toilet bowl in seconds, oh yeah.
Something tells me that is a very dangerous suggestion on a thread about the effectiveness of medicine. I am sure it could eliminate a pain problem if taken in a sufficient dose.
I recomend muriatic acid as a bore cleaner for anyone likely
to compete with me in marksmanship.
Thanks for the information. I’ll give it a try.
You might want to also mention to them that it’s not a good idea to use if they have metal pipes they don’t want to replace.
