I've had good luck with regular, "plain" blue Dawn (no bleach, enzymes, etc.) but it does require that it sit a while (30 minutes+) to work. I've also had luck getting oil-on-cotton (just vegetable oil, though) stains out with the spray Tide pre-treater and with Persil Color Gel, both of which seem to work a bit quicker than Dawn. I would be interested to see your results with the Tide pre-treater in particular.

A 6.1 pH in a soil that fizzes (free calcium/Magnesium carbonate). No anomaly that would produce that comes to mind. Don't bother with a AA test. It's not going to be beneficial this year. We'll assume that all the soil is 8.4 pH and you can retest next year with AA. I don't like making recommendations at the 3-6" level for turf but here goes: Everything in your soil is not only above minimum levels, but decently into sufficient and some even at optimal levels EXCEPT Phosphorous which is detrimentally deficient ( your turf probably did well the first couple of years because sod farms pound their turf with P and you used up the residual that was present). In fact. P is well below critical. Potassium (K) and Boron are also a bit low. but we only need to keep an eye on B and kick K up. It's Phosphorous though, big time. The clay is going to be a real PITA. Edited: Before we go forward: Are you willing/can you afford to aerate twice this year? Can you find/want to pay for Triple fertilizer (10-10-10, 12-12-12, etc) ? Can you find/want to pay for Triplesuper Phosphate ? Can you find/want to pay for Sulfate of Potash/Potassium Sulfate/Sop? Can you find/want to pay for Milorganite (5-4-0) ?

On the main page it will say start a conversation. ..click it. Than type in your subject which must be 15 or more letters...than type in the body of your message than click next...here you must choose at least one place for your thread to goto. I scrolled down and found kitchen table and clicked it..than I clicked post. ..do not assume that just brcause your at the KT when you start your thread that it will show up here...it won't unless you choose the KT.

If you start a test thread in KT and don't want to clutter the forum, you can delete it within a certain time--an hour, IIRC--just ask that no comments be added. Two nights ago the HT music thread (also posted to Kitchens) wasn't loading video's, so I posted a test thread in Tests. My video loaded, so I don't know if that was just a glitch in HT & Kitchens, or if there is a difference in the Test forum. I usually delete my test threads in the Test forum, too. Speaking of testing, I'm adding a video here, to see if it's been corrected:
