Just got the garage cleaned out enough so that i was able to qew wash in there again. Now, during the summer i used to always add 2 capfuls of FD to the qew mix. I did that again today and the temp wsa ~30 outside, ~ in the garage, and the qew left a lot of residue, im pretty sure that it was because of the added FD. Just a tip. Ill try qew by itself next time to see if this really was the problem.
