Tektol Standard (1+9) is an improved version of, and the closest to DS-14. Tektol Neutral is Tektol Standard's cooler brother. It's recommended if you feel DS-14 or Tektol Standard is a bit too warm with your paper. Neutral version is also recommended to remove greenish bias from papers that tend to produce it. What if Tektol Standard is too warm (or greenish) but Neutral is too cool? Mix 'em. They can be mixed at any proportion and you get an intermediate result accordingly. With the dilution range from 1+9 to 1+14, and blending between Standard and Neutral, you can customize your print developer, without handling powders, to match the subject matter, your favorite paper, and your taste. (I keep two small jugs of Tektol Standard 1+9 and Tektol Neutral 1+9 when I work in my darkroom, and mix them in a tray on the fly. I personally think it's very convenient. It took me some time to convince Jon with this idea but I hope creative photographers will see the merit.)

Clearwash is a sulfite-based washing aid but also has some fine tuning so that the working solution keeps better. It's also pH buffered and works nicely together with Clearfix. I don't know if I posted any washing aid formula on APUG, but I put a mix-it-yourself version on the Clearwash description (which you can click on the digitaltruth storefront page). Yup, I know I'm crazy to do this, but again, the production formula is given a few improvements to extend keeping property of the concentrate as well as the working solution. There's no good way to test if washing aid is still good or not, and this is an unwanted risk, so I decided to make sure that the working solution keeps significantly longer than the plain sulfite/metabisulfite solution.
