PBW caustic soda replacement
I've looked at PBW as an alternative to caustic but its so expensive is there a uk equivalent. ..I don't fancy caustic id like something less harmful.

Re: PBW caustic soda replacement
PBW is great but alas expensive.
I use a blend of washing soda and cheap oxy cleaner with a small spot of unscented washing up liquid (Ecover) for its wetting properties.
Super cheap Tesco unscented dishwasher tabs are also a good choice when on offer. Crush and use.
Caustic is good for sealable containers where you can slosh around and avoid skin contact. I tend not to use it though.

Re: PBW caustic soda replacement
This is something I have done some research on but have yet to try out.
American folks seem to use Oxiclean, which is essentially Sodium carbonate (soda crystals), Sodium Percarbonate, and a surfactant. You can't readily get Oxiclean in the Uk.
PBW is essentially the same thing but contains sodium metasilicate which is a trisodium phosphate replacement, which makes the solution more alkaline and improves it the performance of the percarbonate and carbonate mixture. It also contains a chelating agent which prevent depostions of crystals onto your brewing equipment if left to long.
However you can get Dri-Pak Laundry Boost from £2.15 for 750g from Tesco which is essentially PWB without the chelating agents. The ingredients of which are listed here
http://www.productingredients.net/dripak.htm
Sodium sesquicarbonate (a triphosphate subsitute)
Sodium percarbonate
Sodium carbonate
tetraacetylethyleendiamine (this makes the percarbonate work at lower temperatures, something that PBW dosn't do)
Sodium dodecylbenzenesulfonate ( a surfactant)
Laureth 7 (a surfactant)
It perfume free and in theory its cleaning power should be comparable to PBW, in fact better at lower temps. If you wanted to do a long soak you would need to add Ethylenediaminetetraacetic acid to stop crystall residue. I shouldn't think you would need to add sodium meta-silicate because of the sodium sesquicarbonate. If you add EDTA it can be bought on Ebay here

of which you will need to add around 5% by weight.

Re: PBW caustic soda replacement
I use a combo of Sodium Percarbonate (2/3) and Sodium Metasilicate (1/3). Works great.

Re: PBW caustic soda replacement
Greetings all, i have been trying to remove limescale/food debris from a stainless steel commercial boiler (its only on the outlet tube which is hard to get to). I have tried a bottle of vinegar overnight which removed a little but this is a build up over many years so i need something with a bit of umph. I believe some of you use citric acid? would this be up to the job? Edit i have also tried soda crystals overnight soak.
thanks
Keith
