I use both the powder F&G and liquid Ultra Stain release versions for my sister's laundry as she is way too sensitive to scents, etc... Also, I use the liquid Ultra Stain release for spot treating since I use a few different products for my own general laundry and don't want to have to have competing fragrances. Mind you I am not a fan of the overly heavy fragrances and "12 weeks of freshness" nonsense- but I do like some fragrance. Anyway, I digress - the F&G formula in both powder and liquid Ultra Stain release perform very well on both soil and stains as well as general brightening (with the liquid leading the pack). Here in Connecticut, the powder F&G is only available at WalMart and as mentioned earlier, only Target carries the F&G Ultra Stain release liquid. So being the good little detergent hoarder that I am, just stock up whenever I am in either store. Most of our supermarkets no longer carry any powders other than Tide original - everything else is pod or liquid (mostly Tide, Gain and some All products along with Arm & Hammer and Xtra). And I have noticed that supermarkets that carry Persil are few and far between.
