Yes it’s a cleaner/steriliser, there are lots of different recommended dose rates and ways to use “Perk” Palmer
likes it, and there are lots of other references
and everyone appears to have an opinion on the right dose, I recommend about 10g/L in hot (the hotter the better) water.
A bit in the blind filter gets all the muck out of the espresso machine; it gets used to mop the floor as well as clean the Braumeister, fermenters, bottles and kegs, I even use it in the dishwasher to clean beer glasses.
I would rinse, I am the original No-Rinse Sceptic, the only products I treat as no-rinse are the “Shield” type peroxide /silver complexes.
And by good value for money I mean, you can buy ‘Food Equipment Contact” grade 100% pure cheaper by the Kg than Woollies home brand Nappy Cleaner and that’s only 36% Sodium Percarbonate – balance filler so for a third of the price.
OK I like Perk; sorry if I’m sounding a bit evangelical but it’s the best cleaner I have ever used.
