we have soft water so cant see this being anything else but beer stone. especially as it only hits the coil where its submerged. in any case, do we have any DIY/from the kitchen/garage/etc type remedies? brewed last weekend, must not have noticed it before it dried. today i was going to throw some cider together but i wanna get this off the coil before i make up the batch. and i wont be able to make it to a brew shop any time soon.
other than vinegar and concentrated star san i dont have any other acids around. i think i might be able to get some 30% vinegar, neighbor uses it for weed killer.
TIA
