These sheets get your washing clean! That's the whole point! I made sure I didn't overload the washing machine, which I think is important to make sure it was a fair trial of how well the sheets would clean everything. I used only half a sheet for lightly soiled loads, the result was very good, and a whole sheet for more soiled items, again a very good result, nice and clean as well as smelling fresh. I was pleasantly surprised that soiled white pillow cases came up clean and fresh too. I used my own brand of clothes softener in each wash. I'm very pleased with all wash loads carried out. I believe there's no bleach in the product, which is what I want, as I've noticed some fading, particularly with black underpants, when using non-bio powders which contain bleach. I was surprised when I discovered this as I did not expect bleach to be in a so-called 'gentle' washing powder. I will carry on using these sheets for the forseeable future! The only small grumble is that these sheets are quite expensive, that's one reason for not over-using the sheets in each wash and, in my opinion, it's unnecessary and wasteful.
