Sounds like Matt and Chris are blowing smoke. Would smoke be counted as powder or foam?
Many years ago, back when powder was in (before pressure washers!) I developed a "powder" that was actually a soap. We would spray it up into the duct and left it. The next time we came back, we hosed (as in garden) the duct down and it came out like a new penny. This was particularly good with Chinese. This was just getting good when the No Powder rule came down. Too bad.
Thoughts?
