Looks reasonable.

Try to get the muriatic acid, borax, and bleach locally. Be very careful about storing muriatic acid -- it's best to store it outside, inside an old covered garbage can, or the like. The fumes -- even tiny amounts -- can damage wiring and other metal bits in a garage. Muriatic acid and borax will keep indefinitely, but the borax box has to stay dry and the muriatic acid bottle must not be exposed to sunlight during storage.

Good luck!
