We recently got our first dishwasher (having only briefly used one in a rented place before). It's a slimline Bosch in case it's relevant.
I checked Which and got the best buy dishwasher tablets which are the Fairy Platinum Plus ones, and they do clean well. However, if we put plastic (e.g. kids bowls and spoons, tupperware), silicone (spatulas, baby suction bowls, etc), or oven trays (Neverstick which is dishwasher safe) then it tastes completely of dishwasher tablet - an overpowering flowery taste and spoils whatever food touches it, including anything baked on the baking tray etc. It sometimes happens to normal plates and bowls too.
I've tried using different settings in case it was due to using eco mode but it hasn't changed. I can only assume either it's the type of tablet, or possibly tablets are too powerful for a slimline? But tablets come recommended in the booklet...
Can anyone recommend what tablets give a great clean but no aftertaste? I really want to start putting everything in as I'm currently doing so much handwashing it defeats the purpose!
