I am Possitive that ALOT of people are using HCL(hydrochloric acid) to sterilise If enough people responded to this message Im sure you would see Im not the only one useing it. it's extreamly popular since Dr.Clark Talks about it everywhere in her newer books But again if people are to shy to respond to this letter than just realise that when I tried it Imediatly my teeth began to dissolve and at least 7 small chunks broke off my teeth AND THATS PERMANENT I DO NOT RECOMMEND HCL ACID EVEN AT 5% strength. I sure wish this wouldnt happen as HCL is the perfect chemical to kill ALL parasites ALL BACTERIA ALL VIRISES but yes even at 5% strength it Dissolves ANYTHING
