Persil Detergent Confusion
I have a question on the varieties of Persil laundry detergent. I know that Henkel makes many different formulations but I am concerned particularly with two: Persil Universal Powder and Persil Universal Megaperls (also a powder):
Now, the confusion surrounds amounts and value. If one considers that the Megaperls can do ~40 washes and the Powder can do ~80 (both using the largest boxes available of each (around 2.7 kg & ~6.4 kg, respectively)), a question of concentration and value comes to mind. The dealer I bought mine at said that the Megaperls was for front-load washers and the Powder was for top-load washers. But, nowhere on the Persil Store website does it mention HE vs. non-HE. Also, Megaperls is supposed to be more concentrated so you can therefore use less but the amounts one can do per box seems to differ. Then, when you consider the price per box (in my area it's only $14 more for the larger powder) something seems a little fishy.
I wanted to get some opinions on this. I bought the Megaperls and haven't tried it yet but, it seems like for only slightly more than double (1 kg more) I could save quite a bundle. I just assume I would have to dose slightly more (maybe around 1/4 more) per load.
The Persil Store has slightly different descriptions for both products (the Megaperls mentions Anti-Greying formula) but, when you actually look at the boxes of the products (you can enlarge them on their website) they both tout this feature.
I am really confused! Help please.
