I have noticed that the inside of my convertible top is getting rather dirty. I use Raggtop on the outside but how the heck do I get the inside clean again? I usually try to use the boot when I am going to leave the top down but running around town putting the top up when I have to go into a store or on long trips when I have things inside the car I can

 

I, like many people, don't do the inside very often - maybe I've done it twice in the 5 years I've had the car.
First, I'd wash it with car wash soap just like you would the outside, but use a squeezed out sponge or cloth. This should get the bulk of the dirt and dust off. Then, when it's dry from your wash, you can go through the inside with 303 just like you do the outside. Since the inside doesn't get direct sunlight like the outside, it not really necessary to 303 it very often. Get ready to do contortions for the rear portion and be careful not to break your windscreen if you have one.

 

Once you get it clean, use a damp micro fiber towel several times a year to clean up the dust. I've done this about every 3 months with mine from day one and it looks new inside.

 

A lighly dampened Mf towel is all you need to clean it.

 

Thank so much for all who replied. I will be doing a total car cleaning in a couple of weekends. XVIPER, too late on the windscreen. I bought the 3/4 one from Ricks and snapped it like a fresh carrot because I forgot I had put it down. I had been real good about always checking to make sure I had not left it down when I put the top down. But the one time I didn't....well needless to say it was a $100.00 mistake that I won't be making again.

 

you can also use the brush attachment with your vacuum and get most of the dirt & dust...
followed by the suggestions above-

 

I would use a vinyl cleaner that doesn't require rinsing. Meguiar's makes one in their professional line. I'm not what the number is (maybe 39), but it's called Heavy Duty Vinyl Cleaner. A damp microfiber as already suggested is a good method or you could also use Meguiar's Interior Quick Detailer.
