Hario Switch

“I feel like the more I rotate my brew methods, the more I notice the nuances of each. Especially if I haven't visited one in a while I tend to be impressed with what comes out. You might have already tried it but I soak a 1:1 ratio of vinegar and warm water to remove tea stains from my plastic carafe, don't see why it wouldn't also work for coffee stains. If you think the brewer is shot then I'd give the hario switch a try! I have a knock off that is holding up very well. Top portion is glass and bottom is silicone. Only plastic piece is the switch itself”
