"A putty knife or drywall blade would work.  Nothing aggressive like a paint scraper.  You have to get back in there.  So you might be using some type of handle extension. "

Moisture/Mold on rim joist;

In the cold Wisconsin winter we often see condensation behind fiberglass batt insulation on the rim joist. This is due to basement or crawlspace water vapor reaching the cold surface behind the fiberglass. Sometimes it has been chronic enough to cause mold.Two-part SPF is a great way to eliminate it from happening. Okay, so what are your thoughts on spray foaming over the mold? Let's also assume it's middle of winter and the sawn lumber rim joist is noticeably wet behind the F.G. How important…See More

"A common cause that I have seen is undersized gas supply piping, especially when a combustion appliance is added to the line. Undersized gas supply pipe = lower gas pressure => high CO"
