Okay, so I was skeptical at first about these plastic bags for cleaning mini splits - I mean, how good could a glorified shower cap for your AC really be? But holy moly, this thing actually works!

The material feels like a heavy-duty trash bag but with stretchy edges that cling to the unit. When I sprayed cleaner on my disgusting dusty AC (eww), all the black gunk just dripped right into the bag instead of my white walls. Game changer!

What surprised me most was how universal it fit - my weird shaped LG unit and my neighbor's rectangular Daikin both worked perfectly. The elastic edges just stretch to fit whatever you've got.

After use, I just took it outside, hosed it down (so satisfying watching all that dirt wash away), and hung it to dry. Three cleanings later and it's still going strong - way more durable than I expected from something so simple.

Pro tip: Definitely do the messy part outside if you can. That first cleaning released what looked like five years of dust bunnies having a rave in there!
