Pick up some swimming pool acid at HD (sulfuric acid) and soak the bottles/glass for 24 hours. Works like a charm on Corona bottles!. BUT BE VERY CAREFUL! IF YOU WANT TO DILUTE THE ACID WITH WATER ADD THE ACID TO THE WATER, OTHERWISE IT MAY EXPLODE IN YOUR FACE! Please, just be careful with acid!
Would be interesting to see a poll by age ranges and brewing types (3v, extract, BIAB, etc) of HBT members. I'm one of the ancients and don't know how to set it up (can barely find the "enter" key on the keyboard much less find the damn keyboard!).
Getting old sucks double! Maybe triple! I'm 75 and used to be a contractor. Now I do "handyman" work. Takes me half a day to change a faucet washer! Lesson learned; don't get old!
