debrak_2008, Why not simply add a recirculation system to your hot water line? This will ensure every tap in the house has almost instant hot water. gates1, I don't think you'll get much build-up from powder detergents. For the most part, when you add water to a substance and then evaporate the water, you're left with the original substance. Liquid detergents are so gooey and sticky that they are bound to cause build-up problems in the detergent drawer as well as the machine. I've never had powder detergent cause build-up in the drawer, ever, and it's unlikely that it would cause problems in the washer either. I also think overuse of cold washes and fabric softener are definitely factors. Fabric softener is released during the final rinse. That means whatever is left in your machine after the final rinse will evaporate and leave a slight oily residue in its place. If the next wash uses cold water, it's unlikely to pick up that residue and may actually deposit more residue on top. I think this whole issue starts and stops with fabric softeners and liquid detergents. Hot water washes in themselves don't necessarily solve the problem, but can prevent it from happening in the first place by limiting the amount of residue left in the machine. Cold water washing exacerbates the problem because it is not hot enough to remove the fabric softener/liquid detergent buildup left from the previous wash/rinse. Use powder detergent, dilute the fabric softener or use less, and wash regularly on HOT. For those using liquid fabric softener, it may be advisable to start your "laundry day" with a load of whites on the HOT cycle and progress to cooler cycles and darker colors. The reason for this is simple. The last time you did laundry, your machine had a very slight fabric softener residue left in it from the final rinse. To have the best shot of removing that residue, start out with a HOT wash.

@mamapinky... I'm not so sure about Water Chemistry. Me & Larsi.. have soft water, his softened, mine natural. As do you, IRRC. There may be minor changes... but it shouldn't be significant enough, to cause a huge problem. P&G Powders can apparently handle the differences in all three of our water conditions. So why can't a TOL Detergent like (American Persil) not? That's what's disappointing. Or maybe me & Larsi.. are just odd-balls. We have a Persil Curse placed upon us, and American Persil will never work, lmao ;)

@rococogurl, I'd send you a PM, but I can't figure out where your "Message" button is. :/ I'd be more than happy to send you some though. For what it's worth.. if you didn't know any better, the beads look exactly like Real MegaPerls, and the Scent is dead on. But... it's like it's missing Oxygen Bleach completely, or it doesn't seem to activate at any temperature (40*, 50*, or 60*). And... for it containing so many enzymes, you'd think it'd clean up anything thrown at it, even if it didn't have oxygen... but it doesn't. It's like pouring in a cup of table salt. What really bugs me... or sets me off though, is even with the German Universal Powder, or German Megaperls.. despite being low-sudsing.. you still see some small bubbles on the glass. This doesn't have that at all. It's like nothing is there. I don't know. It's not like someone dumped something else in the container. It represents what the product is supposed to be, but... it's like nothing is really there, but fragrance.

Jase. With so many different stores having Persils on mark down clearance prices and the new Persil packaging, I think their just getting rid of the old to make room for the new Pro 10 Technology....yet to be determined if its just a label change or a formula change.My local Walmart has all the different varieties of Persil on markdown and the new Pro 10 on the shelves except Pearls. I'm watching for them lol
