Spridget Windscreen Washer Bottles

["Wiedemeyer" <boxweed@thebest.net>]

Does anyone know of a way to clean the white plastic windshield washer
bottles to get the crud and stains off/out and then bleach them back to
their original white color?  Or, if this is not possible, does anyone know
if original style bottles are still available anywhere for the Mark I
Midgets or Mark II Sprites?

Thanks,
Bob
