Product review (5 stars): Gets into areas you can't reach.
Happy Customer! I don't use this on my refrigerator anymore because of the fridge design change, but it is effective if you have coils open to the outside.  Now I use it on my dryer to clean the open area into which the filter fits. No matter how diligent I am about cleaning the filter, it seems some lint still drops into that void.  This gets into all parts of that area and you will be amazed at how much lint comes out.  Every time I thought it was clean I'd find more in little spaces. Over time I'm sure this saves energy and reduces the fire hazard.  I don't use this often, but when I do it works great.  How else would you clean that oddly spaced area?
