Wanted
Re: Wanted
What's your pbw made up of and where do you get the chemicals? I've heard a 2:1 mix of sodium percarbonate and sodium metasilicate with a bit of calgon thrown in as a chelator does the biz, but haven't got round to buying/making any.
Can't help with your other question, sorry.

Re: Wanted
Off eBay seller called water minerals ltd (I think) its sodium per carbonate 45%, sodium metasilicate 30%., sodium carbonate 25%. Mixed by weight. Had no issues so far and it's about 2/³ price after postage vs pbw. Cheap chlorine to wash down damp moldy cellar is what I'm after. 29p super market stuff is fine but I use for pool too so trying source 14% not 2% super market stuff.
