Is there a means to clean the foglight reflective area? Does the outer covering come off? As everyone probably knows the bulb area is a separate compartment from reflector.
TIA

I'm not sure about Escalades, but if you want to get in there, you can just go up to a gas station or a dealership and ask them to use the tool they use to replace lightbulbs with to pop off the covering. After that, just use some good ol' windex to shine it right up.

car wax helps also. i use it on my headlamps. makes it look brand new...
