Looks like a good product. So you spray this into the HVAC box and it foams up. Now the dumb question...How do you get the foam out? I would assume flushing it with water and a hose?

Any time. If you need anything else just ask. Feel free to jump in on any of the pointless threads in the lounge.

Either a hose or it breaks down on its own and runs off.

I'm going to jump in here because the info Mike speaks of was at one time in this Forum before I had control of it, and was repeated in a competing Bonneville Forum thread recently. And here'* a pic familiar to some of us (you can surmise whom it may be)



PLEASE!. Do not use this product in the interior of your car, nor in components such as the Evap or Heater Core. which handle the air you breath into the cabin. It may well evaporate quickly enough for outside carb or brake cleaning. But never completely There are residues. Residues that cause cancer and respiratory ailments. And fabric and fibers in the cabin can "lock" these and release them slowly. There are products made and tested for core cleaning. The writer of that article used no research and little brain when he wrote/suggested it.

I would never spray anything but the right substance, and I used to have only one reason. Now I have two. My newest reason is that the old administration kept pestering people and banning everyone over some new mods that were thought up. They said their aim was to keep everything stock, but then they turned around and cleaned stuff with caustic chemicals that weren't right for the job. Way to go, guys. My original reason is very American: You can sue if you use it right but it doesn't work. If you use it wrong and you get hurt, then sue, you're simply a douchebag.

This is just a few concerns related to the use of carb cleaner.

Not bugging at all! Let'* keep working this until you get some heat in there. I'm imagining that even at -30F, as much heat as your car has possible, it still won't eliminate the need to wear gloves, hats, etc.
