Product review (5 stars): Excellent for removal of built up lint from dryer vent
I purchased two packs of these Deflecto Dryer Duct Cleaning Kits because I needed about 22 feet of extensions, and one kit has 12 feet. There is an extension pack you can purchase but the price was around $32, and the kit was $19.99 for the same 12' extensions plus an extra brush. I followed the instructions and wrapped the extensions together with duct tape so they wouldn't separate deep inside the duct where I would have a very hard time trying to get them out. I read the other reviews about the enormous amount of lint that people removed from their ducts, and I was amazed how much lint came out. I nearly filled a grocery bag. I also watched a video on YouTube using this product and the amount of lint that was removed was crazy. Use a drill as instructed because it will loosen the packed lint better than if you just try to turn it with your hands. I cleaned from the outside vent first, then from behind the dryer. Add an extension one at at time as you go deeper into the vent. This product is outstanding. Our dryer has never worked so well. We thought our Maytag was a lemon but the whole time it was just the duct packed full of lint.
