Adding some soda crystals to your washing up as well as Fairy (or whatever) will increase its effectiveness. On some pans I only use soda crystals. I also use them in the washing-machine instead of detergent. They clean clothes and keep the machine clean.
We have noticed a big change in all types of washing up liquid both cheaper ones and the premium brands . The water goes all horrible and you have to use a lot more than you used to do . I think they must be using horrible palm oil and cheaper " ingredients " It's all about the money in everything.
Has there been a change in your water supply, Alie? I know it's quite hard in your part of the world already. Here, because of possible water shortage this summer, they have combined our nice soft water supply with water from a nearby borehole which has made it harder than usual.
I always buy Fairy but it lasts me a long time as I the dishwasher a lot. Dishwasher tablets vary a lot. I buy the expensive ones but try to stock up when they are on offer.
I use Sainsbury’s sensitive one for the sake of my hands but despite using the dishwasher too I seem to get through loads of it... mainly ‘cos I’m trying in vain to get it to froth up.
.......have a habit of using Sainsbury's cheapest washing up liquid - and find that the bowl and sink are now scummy when the bowl is emptied? This seems to have started several months ago. It doesn't froth like it used to. What has changed?
