I first looked at this site as I was disappointed at the results I was getting from Persil liquid, both white and colour varieties. I took the advice and swapped to "big box" Ariel. Very pleased with results, also started washing more at 60 whenever possible. Since then I have swapped to big box Daz for whites, much cheaper than Ariel and better results. I have to say that my electricity bill has increased quite a bit since starting the 60 degree regime. I have a fast forward programme that reduces the time from 2.30hrs to 1.30hrs but am not sure if this cuts down on the washing time or number of rinses, since the machine is in the cellar I can't really monitor it. Does anyone have the answer! Greenhils
