Plain dish soap and
water. First rinse with
water from a hose, then wash with soft sponge and soapy water, then rinse again with fresh, inside and out. Towel dry with soft terry towel.
Or, a friend of ours has always used Mr. Sheen spray and a soft cloth.
If you don't want to use the hose, we've been using Novus #1 Plastic clean & shine. We've also used Meguair's cleaner, followed by the polish. You can find them in auto
parts stores, for use on
lexan headlamp covers. The polish removes minute scratches, which cause "hazing".

PS. If you are most
marinas in the developed world, you'll still be getting tiny drops of jet
fuel,
diesel exhaust, brake dust and dirt dust inside and out on your "clears", as well as
salt ocean spray when you sail. Pray for rain.
