Re: muriatic acid ratio
Jeff;
Always remember: There is "Muriatic" Acid and there is HCI Hydrochloric Acid.. The latter being 100% HCI, Muriatic Acid is about 35% HCI (need to look that up to be sure). So, a 5% mix of HCI is a helluva lot stronger than a 5% mix of Muriatic Acid! (Battery Acid is the same way.. it is not 100% H2SO4)
A simple "Five Percent mix" is easy to figure.. Five goes into One Hundred Twenty times (20x5=100).. so 5% would be One Part Muriatic Acid and Nineteen Parts Water (distilled) for a total of Twenty Parts..
