3% hydrogen peroxide is a common antiseptic; you should find it in
your local chemist (drugstore for Americans) or any supermarket.

37% HCl (hydrochloric acid, aka muriatic acid) is used for two common
things: cleaning cement/brick/stone for painting, and adjusting pool
pH.  I found mine at the local hardware store in the paint section.
