I bought both the nextzett Klima-Cleaner and the Lubegard Kool-It.
The spray nozzles nozzles are actually interchangeable. The Kool-it just has a straight nozzle, whereas the Klima-Cleaner has a tri-pattern nozzle that spreads its out. I would say the spread nozzle would work if you went through the drain tube, but I preferred the straight nozzle for going through the blower fan area. You could just cut the spread nozzle, and crimp it a bit for the same results.
For sure, the Klima is a better value. It says 6 oz vs 10 oz, but that is clearly not true. The Kool-it shot for like 6 seconds and the can was empty. The Klima just kept going and going. I must have filled the evaporator chamber like 4-5 times.
One caveat, make sure the spray tube is ALL THE WAY inserted into the white cap. ALL THE WAY. Otherwise, it has the habit of blowing off randomly.
After using both and draining, I ran the fan with the windows open for a few minutes, then the AC. It was blowing clean, cold air. No more faint mildew smells.
The rest of this is vehicle specific. Kia Sportage 2018.
1. Open the glove compartment. There is a clip on the outside, right side. Squeeze the clip and slid off. There are 2 knobs inside, left and right. Rotate CCW and remove. The glove compartment should drop.
2. There are still two pins holding the glove compartment. Squeeze the end of the pin to free and pull out. You will need to support the glove compartment to make it easier to pull the pin.
3. The cabin air filter has a cover. Squeeze the clip on the left side and slide out. Remove the cabin air filter.
4. There is an undercover for the blower fan. Two recessed clips near the front you can carefully feel. Pull them toward you and you can pry down the cover. Requires a bit of strong fingers for these clips. After you free the front of the cover, there are two foam covered tabs in the back you can wiggle out.
5. You can remove the blower fan with 3 philips screws. The fan plug will require pliers to squeeze the tab for removal as it is very tight.
6. The blower fan was blocked by a plastic housing in the front. I removed a screw in the front, and the housing loosened enough to free the blower.
7. I taped an endoscope to the spray tube, placed down a flashlight inside the blower housing facing left, and with a laptop, I was able to see inside clearly. If I was to redo, I would 3D print a holder to make the tube+endoscope more rigid so I could see deeper in and easier. Possibly also make it a right angle spray to hit the coils directly.
I was able to liberally coat everything I could see, and thoroughly fill that compartment. Then wait for the foam to liquidize and repeat. I did not worry about the blower resistor as from what I can see with the endoscope, it was well protected with its position.
