I recently replaced old dishlex with Miele G5000 dishwasher. They gave a box of example tablet, Ultra Tab, it works really well.
However, I have been using the cheapest Finish Classic (now discontinued). Question is that after wash, on area where there is some water residual on dishes or plastic boxes, it feels very slippery. I tried different washing mode, only the 75c mode works better but the slippery water residual still there. My old dishlex uses lot of water comparing to Miele, but it was not picky and worked with most tablets.
I am just wondering if anyone sees the same issue? or the cheapest Finish Classic is not compatible with Miele?
Remarks: I buy tablets based on discounts, so I also tried Finish Powerball Ultimate, it works really well with the Miele.
** Correction, I mentioned Finish Powerball Classic, but it is actually just Finish Classic
Try powder instead. The Aldi one is excellent and cheap enough to try and experiment.
I'm guessing the tablet does not breakdown quick enough in the new dishwasher leaving you with some residual slime.
