I have been trawling through various sites looking for a detergent for use in a pressure washer.
Tried tool companies, supermarkets and google search but the cheapest I can find is £10 plus £4.99 postage even tesco want £12 straight from the store.
Do Aldi or Lidil sell it?
I originally thought I could use a soda crystal solution but these react with aluminium and the gun and hose have these types of connections
I would therefore be grateful for any cheap deals or hints
