You are paying too much for dishwater tablets – buy these instead
To see if I could tell the difference, I put 15 of them to the test, trying them on a mixed load including tea-stained cups, glasses with lipstick marks, plates smeared with eggs scrambled, as well as casseroles encrusted with more eggs and some with dried eggs. -on the baked beans.
So how did these 40p tablets perform? For the price, I was expecting a game changer – Daniel Craig going around and doing the dishes, maybe, or failing that at least some impressively clean pans. But the results were quite close between the top and the bottom of the price scale. Most of them did fine with the tea cups, but none of the detergents removed lipstick or cleaned the scrambled egg molds properly. Despite all these flashy claims, we’re still going to have to do some things by hand. Live and leave the dishes.
Rinse aid breaks down the surface tension of the rinse water so it falls off easily, rather than collecting in droplets on the surface of plates and glasses where it dries, leaving marks.
More expensive dishwasher tablets include rinse aid (sometimes in the red ball in the middle), but if you’re using cheaper, no rinse aid tablets or powder, it’s essential if you want to avoid stains of water.
Figure out that you’ll be using around 5ml in each wash, so with a 400ml bottle costing £3.50 and a clean brand around £1.90, that’s around 2p to 4p per wash you’ll potentially save when you use “rinse aid included” tablets. , or £1 to £2 on a box of 50. That said, some experts think it’s a good idea to keep the rinse aid compartment filled, no matter what detergent you use.
Why do glasses become dull and cloudy in the dishwasher?
It’s possible that the cloudy buildup is just limescale deposits, which can be removed by soaking them in vinegar. Probably not, however. This is almost certainly a permanent etch on the glass, caused by the “chelators” in the dishwasher detergent. These, ironically, work to reduce lime deposits by binding to metal ions such as calcium in the water, which also helps them lift dirt.
But if your water is already soft (and the salt dispenser you religiously filled will help soften it further), then they can attack the surface of your plates and glasses, taking away the shine. The more expensive tablets promise to protect glasses from damage, but come with a hefty price tag. Still, it might be worth keeping a box in the back of the cupboard for those days when the best glassware has come out.
