Bob- I have a box of Tide Ultra Oxi powder, but haven’t purposefully tested it yet. In fact, I should do my stained flour sack test for all the detergents in cool water to see if the results are truly any better than in warm. It seems like stained kitchen towels come out cleaner in cool water with a number of the detergents I rotate through. I’ve used Tide Professional powder quite a number of times and get great results. Haven’t tried any of the other powdered Tide variants. The only downside I can think of with Tide Pro is that it comes in one size: 155 loads. I’m a laundry junkie and wash a load almost every day, so I burn through a detergent stash fairly quickly. If you buy a box of it on my recommendation and hate it, you’ve got a LOT of detergent on your hands.
As far as liquids go, my recommendation would definitely be Tide Plus Ultra Stain Release.
Your laundry habits are quite different than mine and I have very soft water. Most of the loads I wash only fill the tub about 2/3 full—sometimes only half. Loads of bath linens are always maximum capacity. I generally wash that load using the Whites or Sanitize With Oxi cycle in hot water. Same with sheets. Whites has a maximum wash tumble time of 30 minutes, which is fine. If I feel like the load needs more contact time with the detergent solution, I’ll use the Sanitize With Oxi cycle on light soil, which is a 50 minute wash tumble. The maximum wash time on that cycle is 80 minutes, which I only used once just to check it out. What I like about the Oxi cycle is that all the spins are a few minutes longer than the Whites cycle and the two rinse tumbles are a few minutes longer, as well. Towels emerge from that cycle noticeably drier compared to the Whites or Heavy Duty cycles.
I’ve mentioned that my favorites are UK Persil Bio & Non-Bio, TideMatic (for front-loaders) and ArielMatic (for front-loaders) from India, but they cost an arm and a leg. I lead a simple life, so detergents—of all things—are my splurge. The party selling ArielMatic on Amazon is down to only eight 1 kg bags and the price is a stunning $29 per bag or about 84 cents per ounce. Ordering TideMatic or ArielMatic from NavaFresh, which specializes in imports from India, is crazy expensive, as well.
I’d encourage you to try one of the Tide variants you have on hand in cool water and see what the results are. It may be something you try once and say ‘Never again!’ or you may find it works well for certain loads. You tend to wash maximum capacity loads, so might want to use a cycle other than Normal, which will probably be very stingy with water. The quirk with the SQ is that on the Normal cycle it fills to a certain level and that’s it. It won’t add another drop. I find a load of bath linens soaks up all the water, which proceeds to tumble for 50 minutes with the load being wet, but not fully saturated with water. It refuses to add any more water, unlike on the other cycles, which will add more if a particularly absorbent load soaks up the initial fill.
I found a reference to Coldzymes at the Tide website in the pacs/pods area. Thought there was a splashier example of it somewhere on the site, but don’t have time to search right now. Check the last sentence in the blurb shown below.
