Product review (5 stars): Whirlpool cleaning brush
This Whirlpool coil cleaning brush worked like magic on my Maytag fridge coils.  I got so much dirt out and I was amazed how much dirt collects under the fridge and sticks to the coils.  My wife used it on the dryer and it did a decent job.  For me, it it did the job and more.  I'm keeping this brush ready and loaded for any other job.
