We use dissolvable tablets (from Blueland) with all "natural" ingredients; can't vouch for how true the natural claim is, but we're happy with them and it's one way to reduce plastic; we also get their dissolvable tablets for hand soap, all purpose cleaners, glass cleaner, etc.
I tried the dishwasher tablets and felt like it didn’t clean the dishes as well. We been using the hand soap and other cleaners and I’m never going back on those. Maybe I need to give the dishwasher tabs a try again.
Maybe it depends on the dishwasher. We used them in our previous house and weren't as impressed with them but then moved and our new dishwasher works very well with them.
