I was looking at switching to ecover dishwasher tabs the other day, only to find that Morrisons value dishwasher tabs already are oxygen bleach instead of chlorine bleach. I'm guessing they aren't as good as ecover but I'm not sure that justifies the difference in cost when you are on a budget.
The change to solid soaps is easily paying for itself, even with more expensive better soaps.
Soda crystals to clean.
Eco eggs for laundry!!!
Any other budget friendly switches people have found?
