The only access would the hole for the bulb, my hand is not quite that small. I could remove the lens, and remove the bulb and pour a liquid in, if I knew what would clean it.
At NAPA they seem to be over $250 and only $68 at RockAuto, why such a big difference?
Most problems are on the outside. They're plastic and they eventually dull. There are several products for dealing with it, e.g.:

If there is ingress of moisture, you may wind up with it evaporating inside the housing and causing a buildup on the inside of the lens, including fungus growth it is routinely in dark storage.
This can result from a number of things, including someone replacing a bulb and leaving off any factory gaskets or seals, which causes moisture to enter the housing with cooler air after the headlights have been used and then turned off.
Depending on the cause and the condition, taking it off the vehicle and cleaning it with a solution of trisodium phosphate and sodium perborate and hot water might clear things up.
The price of the headlight assemblies is a function of where they are made. OEM are highest, Taiwanese and Korean middle-priced, and Chinese and some other places in the Orient the lowest.
I'd take a good look at the knock-offs before using one - some of them are pretty miserable.
