Huntsman, thanks for that new research on Cheer.
I found Cheer on an army site for BDU's. I notice they may now opt for any type of detergent.
I just tried that old standby, Baking Soda and 20 Mule Team Borox. Instead of Fels Napha, another old standby, I used some clear scentless liquid soap. (It's the same soap Ive used for over a decade for hunting showers.-Walmart) Still testing, mixing as I need it, for each wash. So far the result is good, with the scentless clothing and non UV showing under the black light in the "dark room".
In fact, I'm going to use the latter, this winter, to wash all my "around the house" clothing with the end formula.
Got away from scented detergent years ago, and might as well save money.
