Bottle: What's this and why won't it come off?

Wow. I know dH from fish keeping, that is liquid rock coming out of your tap. My tap water is just 4 dKH and I'm always trying to bring it up using limestone in my tank. In planted aquaria, we use Co2 injection, which needs hardness to bind it and increase PH buffering.

I find it interesting that my hobbies have crossed over. I'm curious to know how bringing up hardness in beer will affect taste like mineral water, and carbonation retention. I have yet to get a full analysis of my tap water so I can start adding salts properly - other than what I know from my aquarium test kits: dKH, GH, PH, Ammonia, Nitrates, Nitrites, Calcium and Phosphate.

Not that I bottle any more,... but when I did I built a brush using a plastic rod, drilled holes through at the end and pulled cut strips of scouring pad through. Then I just cranked down said rod into the chuck of the drill, put it into top gear and got those damn bottles clean. All swing top - people sell the Grolsch ones used on kijiji or whatever local bartering website is called. Then when your done with bottling you can resell them. New brewers are always snapping them up. Or you can order Grolsch Premium from your local beer supplier and sell them to cut the cost of your store bought (sacrilege I know... ) drinking in half or less.

My grandparents gave it to me. They said it was for root beer.

Hey the riveted steel ones are great too. You should polish it up and give it a coat of boiled linseed oil, these things work really well. I glued two stacked rubber washers up into the bell, so that it releases the bottle automatically after crimping. When I use it I place a beer coaster on the base plate to act as a cushion, still looking for a piece of rubber to glue down.

These things were originally sold as rootbeer cappers during prohibition, I wonder how much actual rootbeer they produced? I kind of enjoy refurbishing stuff like this and putting it back into service. Check out the "hand tool rescue" channel on YouTube, fun to watch old tools being resurrected.

So an update.

I I'm pretty certain it's coming from my no rinse sanitiser the UK equivalent of Stansan, Chemsan (which say it's supposed to be good for hard and soft water a like)

So I soaked my westmalle bottles which I was going to use for my Tripel in Chemsan and it's left the exact same white hard powder chalky powder on my plastic bucket as it previously did on my bottles. It doesn't rub off but if I give it a little scratch it comes off in a powder.
