Window screen residue


#1

Just a note on what happens when you vent through a window screen and then engrave a ton of acrylic:

Happily, it mostly wipes away.

Why yes, that is the healing and cooling air intake fan for my house right outside the window…


#2

If that’s a heat pump, there’s not any air going from that unit into your house. No worries there.


#3

That shouldn’t be an issue for you…just cools the refrigerant in the line. Your air intake should be inside your home.


#4

5 seconds with a toothbrush and rubbing alcohol clears mine up.


#5

Oh good! Not so bad with woods, but acrylic, yeesh.


#6

Although you might want to clean out the radiator coils on that side more often. :wink: Should be cleaned 2x yearly anyway, but… :innocent:
