I mostly clean things straight after use, FV's, bottles, boiler/mash tun. Its very easy and water and a soft sponge will do most of the work, some soda crystals if anything needs soaking, €1 in Dunnes
I sanatise everything with thin bleach/vineger solution.
20L 3 tablespoons of each, this is supposed to make a no-rinse solution, but I rinse anyway.
Others dont like this method but it works for me and hasnt let me down in over 20 brews.
It's extremely cheap, I'm on my 2nd 5L of Lidl bleach @ €1.39 and 7th Lidl vineger @79c.
