Its funny how Persil used to recommend hotpoint, then they recommended ariel lol
I think that they are trying to put less cleaning agents in the powders so they are more eco friendly. I've found that alot of detergents fail to remove stains like old formulations from the old days.
when i got my zanussi washer back in 2001, they gave me a free sample of Ariel Essential Tablets, the original ones which were turquiose and white. now with new washers they don't give you detergent samples
I would do anything for them to bring back thick white persil liquid, the closest liquid that is white, is persil non bio and surf small and mighty.
