Can you use muriatic acid to clean main drain?

There are 6 strong acids , Muraitic ( a.k.a. HCL ) is a small molecule , it has only one Clorine ( CL-) Sulfuric has Sulfur , OXY , thus he can still weigh in after tossing his proton , also Vinegar ( a weak acid) can still weigh lots after it donates its proton ( H+) HCL will eat pipes , galvanization , copper , iron , calcium deposits on bath tub , VERY dangerous acid . But little harm to plastics that have no nitrogen . Nylon and others that have Nitrogen , are destroyed . My friends 12" metal cutting lathe was turned red with rust from a plastic bottle of HCL ( for pools ) . HCL is so strong a "helper" acid , it helps eat gold in Aqua Regia ( up to 82% HCL in the brew) In chem' , there are absorbers called "buffer" or sacrificial additives , that may dilute the HCL effect . Thus to maintain the cleaning effect , you must not dilute . Water is the only solvent that holds the strength of acids. It has no smell ,cause it has only CL- , thus used to lower pH in swim pools . Laundry powder has sodium ( opposite effect of acids ) so it absorbs protons , from your hands , from clothes ,,, Vinegar , or lemon will harden your skin in less than 1 second . The protons stripped from your skin are replaced quickly . In dilute form you can cook with sodium and Muriatic acids . Sodium will dilute acid foods , quick without any funny flavor , because table salt is SODIUM plus CLORINE , your body is accustomed to taking in large amnts of Sodium .
