Home Made PBW

[aweisse]

Hi All,

I clean all my equipment with W3 OXI from lidl, ive also used pbw, and its a great product, but expensive.

Has anyone made their own pbw? Ive looked around and came across a mix of
65% Oxiclean with 30% TSP and 5%  EDTA by weight.

The w5 stuff in purple tub yellow cap yeah? Shifts everything out of my carboys, masssjve rinse and then SS

Yup thats the stuff, i use loads of it too, but its short a chelating agent
This is why PBW doesn't cause scale on your equipment, even with hard water. Oxi unfortunately does not contain a chelating agent.
EDTA (Ethylenediaminetetraacetic Acid, try saying that after a few pints) is a commonly used industrial chelator.

I'm on very soft water so not really a problem can you use SS afterwards to remove the scale?

thanks for that CH

If you have hard water in your area, collect rain water for using with oxi.

Massive rinse using domestic water after using rainwater though

Differently massive rinse with domestic water after and then ss

65% Oxiclean with 30% TSP and 5%  EDTA by weight.

TSP?

These lads have EDTA, free shipping too by the looks of it:

TSP is trisodium phosphate, a cleaning agent.

same company has it https://mistralni.co.uk/products/chlorinated-trisodium-phosphate-tsp

Vermelho and myself were making up our own "PBW" there. Mixing oxyclean with sodium metasilicate. 70:30 ratio. Really does the trick!

Highly recommend MistralNi for some of my more esoteric needs

Jaysus lads be careful with the bucket chemistry on cleaning products, I've seen what farmers mixes can do to plastic

Just rereading some of the stuff online there and noticed the homebrew pbw recipe on HBT and brutus brewery mentions using tsp/90 which is an American product that is sodium metasilicate and not actual TSP
