Found that Walmart has matched it at the same price ($6.37). Good deal if you have Walmart+ for free delivery.

Can this be used to clean portable indoor ac's? Do those even need their coils cleaned?

I bought this at Walmart last week for about the same price. I first looked on Amazon and when I saw the big price difference compared to Walmart, it was worth the drive. Good price from Amazon now.

inherently less of an issue since the condenser is inside the house and its just blowing out the hot air through the tube. Technicall you could but I wouldn't bother unless it's very old with a lot of service hours and you think it's having weird smells or poor performance.

Wear mask and eye protection when use.
You can't use this for the Tesla...unless you have a little tube to hook up to it...to reach to the cabin air filter slot.

For your typical single family home AC unit, get two cans. One can will only get you complete coverage of two sides of the coils

I used a similar product to clean my 20 year old portable a/c that is used in a garage. Mine was dirty and needed a cleaning after all those years.

In order to clean the coils, you have to disassemble the portable a/c (see various youtube videos).

If you are going through all the work to disassemble, clean, and reassemble the portable a/c, I would highly recommend replacing the Capacitor while you are there. Mine was all rusty and puffed out from years of use.

Blown Capacitor is probably the most common reason people discard portable a/c units. Because people think the a/c is dead, but really it is a ten dollar Capacitor that is bad.
