We mix diesel fuel and boric acid together and the cockroaches never came back.Joe Gore

And the bondo patch on it is still holding...If you use a sulfuric acid based rust stopper don't use a foam sponge to apply it- use a rag.

I once pours undiluted white vinegar on one such and the surface bubbled like acid, but it removed it and after some additional cleaning it was back to new.

It's easier identifying the value of a piece of gold than any property, pretty simple, get scales, an acid test, an eye piece and you're in business!

It's very acidic and must be run through a "neutralizer" before running down the drain.

Boric Acid (which is in powder form) works well, spread under appliances; under new base cabinets at install; in the wall voids whenever you open a wall for repair; under carpet pads and around the perimeter of rooms before base trim goes on; inside base cabinets toward the very back; and other fairly inaccessible and dark places you can find.

Stained concrete is great, you can also do a diy which is an acid wash to open the pours, roll on a stain, roll on your sealant and voo - laa.

If the condenser went bad, your lines could be back-filled with acidic sweat.If not cleaned, this could shorten the life of any new unit installed substantially!

Then you can kid proof it in many ways like using plywood under the Sheetrock so they can't put holes in it, making each room furnished including their own refrigerator and each room have a lock and deadbolt.The floors can be done in acid stained concrete that is nearly indestructible, the garage can be divided into storage lockers and one room for an office so you have reason to be there at any time.

You have to account for city requirements and possibility of getting a more expensive and rust friendly materials, due to the acidity of the zone.
