Air Conditioner Condenser Fin Comb, Fin Cleaning Brush Air Conditioner Fin Cleaner Refrigerator Coil Cleaning Whisk Brush Metal Fin Evaporator Radiator Repair Tool (2)

Works great for window units. I cleaned our out, those definitely saved me from denting anything

If your heat exchanger is in great shape dont use the metal brush.

These worked well when cleaning my RV rooftop AC unit and I’ve been able to use the softer brush for other projects.

I found it very difficult to getting it into the coils. It bent more than it fixed. I found that an actual hair comb worked very well. Broke a 2in section off a hair comb and worked a few teeth into an area of coils. Watch some you tube videos.

Good product for the cost was surprised how well it works!

Great value and fast delivery .

So you may have gotten the same confusion as me on this item. I was thinking this could be used to repair damaged and bent finds on the back of ACs. This is just for scraping dust off, which I found doesnt really work that well. I returned this and grabbed a different item on here. Look up AC Fin Straightener and youll see a bunch of the same thing, its a ring with plastic combs for different fin sizes. Also look these tools up on YouTube and youll see what and how theyre used properly before you try anything. If done wrong you could end up bending and causing more trouble, so better to research everything first. Its relatively easy, just requires patience.

Worked great my window unit kept freezing up. Used this with ac cleaning spray . I could not believe the yuck that came out!

Only issue with metal comb is the bristles being glued together. I removed the white band that is around the bristles, poured a little isopropyl alcohol on them and let it disolve the glue. Wd40 works as well. Then i just made sure no bristles were stuck to each other. Just needs to have instructions for comb and it would have 5 stars.

This tool has come in handy a number of times to straighten out smashed window air conditioner fins. Straight fins means better air cooling, and when we use this tool to fix them, the units cool noticeably better.
