Persil is a British brand, it's probably the best washing powder available. Used it when we lived in England in the late 70's. Then it was available in two formulations: Persil Automatic, a detergent for front load automatics and Persil, a soap powder for twin tubs and top load machines. Amazing results in one wash, stained tea towels looked new again. I still use the results from a Persil Auto wash to judge a detergent's performance. Then most everyone used Persil, everything else was used for colours. I used Persil Auto for lights and whites, Bold Auto for a biological prewash(Persil didn't contain enzymes), Surf Auto for colours(sometimes or just Persil Auto)and Lux soap flakes for woolies. Clothes were cleanest ever then. Thanks for posting the commercial, it was fun to watch.
