Minimal experience with various manufacturers presprays other than Bane Clene chems, hard to pass judgement. They've worked for me in the past. Just converted to a Butler and trying many new tools/chems/accessories. I must say, Mark Saiger's Sauce 1 has amazed me. Dissolves instantly, smells great, great soil suspension, and really couldn't be happier with it. Goal was to try many new chems, purchased a few to try but this sauce was so impressive I keep using it. Joe, next order I want to try some of your Soils & Oils.
