Hey everyone, just wanted to share a quick tip that's saved me loads of time and hassle with my coffee machine at home. You know that weird bitter taste you get sometimes? Turns out, it's usually down to old coffee oils building up inside. I started running a mix of white vinegar and water through the machine once a month, and it's worked wonders. Just remember to flush it out with plain water a couple of times after to get rid of the vinegar taste. Simple, but it makes a big difference. Hope this helps someone out there. Cheers!
