I was initially very sceptical about how effective this would be, but I wanted to support such a good cause so I decided to buy one bar to try but imagined I would return to commercial washing up liquid afterwards. I have been so impressed with these bars that I only buy these now and when I used up my shop bought Eco washing up liquid I was amazed how poor that was in comparison with this bar. It is great for cleaning, I don't use my dishwasher anymore as a quick scrub with this after use is more efficient and means I don't have to plan in a full scale dishwasher load and unload into my housework!! I keep one of these bars in a little tub with my washing up brush and the small amount of water that drips off the brush creates a lovely pool of liquid to dip into to, or a solid bar to scrub into the brush filaments. My favourite element of these bars is the smell of real lemons, so much better than the chemical smell of my old washing up liquids. When I wash a hot pan I pour a little of the liquid from the pot into the pan and it releases a wonderful lemon scent as it cleans. Fabulous!
