Our community has rated this post as helpful. If you agree, why not thank

Ok... this has to be a running joke within the staff at this point.

This stuff us always this price. And I've pointed that out the other 2,533 times it was posted over the last year. Lol.

I'm starting to lose faith in SD. The deals are rarely slick, and the "incentive" to post items has made the app become over-run with 3% to 7% off "Deals" on items under $10!

Can we get back to quality over quantity?

Many, many ac units would last a lot longer if more people cleaned their coils and regularly changed their filters.

Agreed, you beat me to the punch. It's like watching the news. You can turn channels and see everyone reporting the same exact story at the same time.

Agreed with the not-so-slick deal. However, I have to say this stuff works really well. I had a dehumidifier that was running erratically so I took it apart to work on it. Inside, the coils were filthy. I remembered I had a can of this stuff and let it rip. I couldn't believe the amount of crap that slid right off the coils. A quick spray with the hose and the 15 year old dehumidifier looks damn near new.
By the way, the reason the dehumidifier was running badly was the bracket that held the thermocouple to the coil had rusted and broke. The thermocouple was hanging loose and the thing was short cycling. I just removed the crusty remains of the bracket and zip-tied the thermocouple to the coil. Also had cracks in the squirrel cage fan that cause a rattle which I fixed with a plastic welding kit.
Clean filter, clean coils, repaired thermocouple and squirrel cage and the thing runs like new.

Well, it's $9 now, so I guess not "always". And I paid $16 in March, so I for one would've been glad to get it at this price.

Indeed, it's not if but when. I've been around a while and can say, without a doubt, that it isn't what it used to be.

Normal price at Walmart as well and picked up in store. I did notice Amazon doesn't always directly sell this product since I needed this last month so the prices are jacked up by third party sellers…so if that's the "deal" that Amazon now sells it at normal price, then sure.
