Muriatic acid is really called hydrochloric acid, HCl, muriatic acid is  
indeed a US thing, and comes in a variety of (mis-)spellings. I do not  
know what "muriatic" comes from either.

Hydrogen peroxide is the correct name for the second chemical though,  
H2O2. Seems just like water, but has more oxygen, which is what we need  
 from it. It is used in "peroxide" bleach. It was used in the "old days" to  
disinfect, similar to iodine (stings too i'm told).
