Have a Whirlpool French door/bottom drawer freezer. The coil set up is the zig zag rows described earlier. We take the front grill off, clean whats accessible with the crevice tool of the vaccum cleaner. Theres still tons of dust. We wet towels and wring them out pretty dry and place along the edges of the refrigerator (which is pulled out). With the back plate on the back unscrewed and tipped we put more wet towels along the floor where the dust is most likely to blow. Then we blow from the front to the back with a homemade compressed air bottle. Takes about three fills of air to do a good job. Replace back plate, replace grill, pick up wet towels with dust trapped in them, move refrigerator back, turn on. Repeat as needed ( once or twice a year). I like the leaf blower idea.
