yeah do the following:

Buy an OXO feather tip brush ($20) or a boars hair brush (pricey). Only use the that brush to clean the top. Don't use that brush for anything else.

Don't put any type of car wash soap on the top. It attracts dust which will get into the threads and cause them to fray when the top is stretched.

As the other poster suggested use Raggtopp Cleanser on the top with the OXO brush. Rinse it with a powerful stream thoroughly. Dry it thourough with a microfiber type towel, good for picking up lint and very water absorbent.

Once dry, use Raggtopp Protectant to "scoth guard" the top. It repels water beautifully. You might want to do this before washing the rest of the car since you'll probably get overspray onto the paint.

For the plastic window use Plexus spray often. Both sides. DO NOT use a microfber towel for this it will scratch the plastic. Use an old t-shirt. The Plexus keeps the plastic from becoming brittle or yellowing. You can keep a plastic window crystal clear for a decade this way.

DO NOT lower the top without warming up the cabin if the outside temp is below 60-65.
And make sure you are warming up the cabin while the car is moving and not stationary. Pull over and lower the top.
