1997 Es300. Need Inside Eadlight Cleaning Options And Info On Speedome

[diiorio]

I recently purchased a 1997 ES300 with 84k miles in great condition. THe only issues with the car are the build up (brownish hazing) inside the headlights (outside is polished) and the Odometer/Speedometer needles do not light up.

Questions:

1. Is there a way to remove or open the headlights (main) and clean the head light reflectors (like with CLR)? IF so how is the best way at removing them and opening them.

2. Is there an easy way to remove the dash display? Are the needles bulbs themselves or are their bulbs behind them that make them light? IS it hard to remove the dash inset and replace the bulb(s)?

Any guides or links would be helpful.
