And you're Pist'n'Broke????

Not saying the BB would be false economy (note the "IF" in larger text) & quite happy to put my name down for 3Kg of PBW if CraftBrewer's reply to my enquiry does not turn out as hoped & the BB goes ahead.

Lets do it Pete, I'll give you a hand to split it up.

My understanding is that PBW's main ingredient (Sodium Percarbonate) reacts when dissolved in water, essentially decomposing into hydrogen peroxide and sodium carbonate, the hydrogen peroxide degrades into water and oxygen, but the reaction, decomposition and activity is also what gives sodium percabonate much of its cleaning-power (and sanitation properties) and is the 'active' part promoted in many 'oxy' cleaning products.Without getting into bulk buys or replaements... The easiest way to save money on your PBS is to re-use it. Like all alkaline cleaners, PBS isn't fi iced once it's done.

Same thing with PBW. I keep a 20L container pre-made up at CIP strength... Use it, then pour it through a straining funnel back into the cube. Anyothing that makes it through the strainer settles out below the tap in the cube. If I'm using any more than a litter or so, I chuck in a tablespoon of extra pbw powder in to top up the strength.
I know this is an old thread, but came across it while searching for PBW/caustic and found this idea.

Saving left over solution, is a good idea, however by that time it would essentially be washing soda (sodium carbonate), which is a useful cleaning and descaling product, but it's not the same as the 'active cleaning' components of PBW. Washing soda is very cheaply available at the supermarket and could (home-brewers in the UK use it) easily be used as a cheap brewery wash and would be essentially the same as saving PBW.
Probably due to the other (10 or so according to quote earlier in this thread) chemicals that make PBW - I might have to try and find out which one.Question ?
Do you guys know why does the PBW seems to remove beer stone where the sod perc doesnt?
A mate of mine in the wine industry gave me a 5kg pack of "DESTAINEX" Peroxy-alkaline detergent powder which is used for stainless cleaning in the wine industry,boy does this clean stainless - quote:clean & remove wine protien & colour films,mildew,black mould & most organic soils from stainless,concrete & most hard surfaces ran it through my system and it removed beer stone,stains in lines,made kegs look new even soaked the oven racks in it and the burnt on crud vertually fell off
pack states contains:sodium carbonate peroxyhydrate,carbonate,bicarbonate,propritary solvent suficant,rinse aid.

dont know if its available to the public but if you can get some you wont regret it
Thanks Brad.
