No bleach.
Stage 1: Use a clean cloth and quality lacquer thinner. Make fast, light passes across the lens face until
the lenses are clean. Still cloudy, but clean. The cloth will get pretty dirty. Turn it often or use disposable
shop paper towels and replace them often. When a new one no longer gets any visible dirt on it, you're done
with that stage.
Stage 2: Wet sand the lenses with wet/dry rated sandpaper, in 1000, 1500, and 2000 grits. Take your time
and work it evenly across the whole face of the lenses.
Stage 3: Polish the lenses by hand or buffer with an appropriate fine grade polishing compound. If using
a power buffer, keep it on low speed and keep the buffing pad well moistened with compound and keep
the buffer moving. It doesn't take a lot to cause it to start burning the plastic. (Melting spots in it, a
actually.) I use Meguiar's no. 82 swirl free polish and a variable speed buffer. (Not an orbital, a straight
variable speed rotary buffer.)
After the lenses are perfect again, you can clear coat them for additional durability, using a urethane clearcoat. Don't use lacquer, it'll probably yellow, and isn't as tough as urethane.
Do the marker lamp lenses, and cornering light lenses, too, in the same manner.
