I recently purchased a new countertop dishwasher because I was getting really freaking tired of washing the dishes myself. Good news is that for the most part, it works great. However, I have hard water, and I'm getting significant white streaks on my silverware and glassware. Fortunately, rinsing those dishes in white vinegar removes the streaks instantaneously. Any ideas for what I can do moving forward to prevent these streaks from happening? I've read mixed reports on whether or not you can put vinegar directly into the rinse aid compartment. Some people swear by it, some people swear at it damaging their dishwasher (FWIW, the manual says to only use branded rinse aids). I purchased a branded rinse aid hoping it would help, no luck. Thoughts?
