Persil washes whiter, and it shows.....
...too bad I have virtually no whites to launder, other than a few white dress shirts!!
Last May while in London, I visited three different Sainsburys Express stores within walking distance of my hotel, and all three were sold out of Persil. That should have told me something, unless one goes on the assumption that Persil sold out first because of its name recognition among tourists (one of the three stores was in Paddington Station, another in Bayswater, etc.). I'm aware that a larger "real" Sainsburys or Tesco probably would not have been sold out of Persil, but lack of time (and scarcity of full sized stores in central London, plus the ones I could locate were not near tube stations) forced me to settle for what Sainsburys Express had on its shelves.
I settled for Ariel Bio powder: I needed to wash a few things in the hotel room sink, but my main objective was to bring home several boxes for stateside use. I still had some Via Colour from a trip to Sweden (Unilever's name for Persil in Sweden, with ads and packaging identical to UK Persil) and it slightly outperforms the Ariel here at home---but both Ariel and Via outperform our stateside HE powders such as Tide HE and Gain HE.
Because I flew home from London in Economy and was thus permitted only one bag at 50 lbs/23 kgs, I placed the four boxes of Ariel in my cabin bag (a wheeled backpack with retractable handle). American Airlines has limits on the dimensions of cabin bags, but not on the weight (I believe British Airways is the same, however when they specify 22 inches/45 cm, BA means wheels and handle included).
I was selected for random cabin bag inspection at Heathrow T3 (American Airlines) and the officer did ask why I was bringing four boxes of detergent home to the USA. I explained that US detergents are inferior because FL technology is still relatively new here (well, it's old, been here since the 1930s but what I meant was that a majority of the US still uses TL machines, with FL now a majority of new washers sold) and that UK products give superior results.
No worries, he let me through and no, he did not ask me why I had not purchased Persil, which enjoys a royal warrant from HM The Queen. Had he asked, I would have answered that someone's mum (The Queen in this case) knows that Persil washes whiter, and it shows.
