I have used watery soap in the past to clean finger-oil off filters, followed by tap water, followed by distilled water and dry by hairdrier: glad to see I wasn't doing anything too silly...


Now, for English water, I have to segue to my beer brewing. I dump a "Hell of a lot" of mineral salts to replicate English tap waters to make British ales.
The mineral concoction is commonly called "Burton Water salts
Don't forget to add enough chlorine to make you drink the water holding your nose shut & flouride (whether you want it or not)... Actually, I'm tickled pink you can actually buy a product designed reproduce English water - I hope it's to reproduce spring/stream water rather than the stuff that comes out my tap though!


Cheers, Bob.
