Cleaning dust from the very most inside grill

I have a refrig. that works great, but am concerned about the dirt and dust I see inside the bottom of the refrig. Not the pop off grill or the one behind that. I can get to those and clean them. But there is another grill behind those that you can’t get to and it is very dirty. No brush of any sort can be inserted there or any way to vacum it out. I am afraid that eventually it will cause damage to my motor. What can I do?:frowning:

[FONT=Arial]Do not know if this will help but here is how I clean mine.[/FONT]
[FONT=Arial]Note that my fridge is opposite an outside door and it has good rollers so I do not have to worry about damaging the floor.[/FONT]
[FONT=Arial]I remove the front kick plate, the drip tray and the rear access panel.[/FONT]
[FONT=Arial]Open the house door and roll the fridge to the door.[/FONT]
[FONT=Arial]Then blow it out from the back using my compressor.[/FONT]
[FONT=Arial]This way the majority of the dust is blown outside.[/FONT]

[FONT=Arial]A leaf blower will also work or if you have a vacuum where you can attach the hose to the exhaust. If using a vacuum I would remove the dirt bag from it so you get the maximum exhaust air flow.[/FONT]
