He told me to stick with the concentrate the dealers sell (or get it online for cheaper if possible) plus distilled water. I was skeptical but gave it a try. That was about 15 years ago and since then have never had clogged washers. Not a large enough sampling to be statistically accurate, but just thought I'd pass it on.
