Hi Guys

Anyone out there know if i can use my pure water window cleaning water for home brewing.

I use a four-stage RO system only. I've heard that some purification methods are carcinogenic

Any help appreciated

You don't want pure water for brewing, especially of you're mashing your own malt.
The breweries in Burton on Trent started there because the water is hard and full of Magnesium Sulphate, it gives the best conditions for the enzymes converting the starch to malt sugar.
I often put a teaspoon or two of Epsom Salts in my brewing water.
