Homebrew PCBs

Yes, in Bunnings but look in the garden or pool section rather than the 
paint department. These days in Oz they charge a hefty deposit on the 
container. Probably its most common usage here, apart from adjusting Ph 
levels in swimming pools, is to wash down brickwork after the joints 
have been pointed, raked or whatever. It removes all the surplus cement 
and lime.
