Here is the "Cleaning and care of the convertible top" section of the 3-series convertible owner's manual (downloaded from BMW Owners' Circle ). It's lengthly, but complete:
 
The appearance and life of the convertible top are highly dependent on its proper care and operation. You should pay particular attention to the following instructions if your car has a lightcolored top.
 
Protect the vehicle from exposure to intense sunlight whenever possible by parking it in the shade. This will help to prevent the paint, rubber and fabriccovered parts from being worn out.
 
Never stow the convertible top in the convertible top compartment when it is wet, dirty or frozen, since this can cause mildew stains and chafe marks.
 
To prevent mildew stains, do not keep the convertible top enclosed in the convertible top compartment for any extended period of time.
 
If the vehicle will be parked for lengthy periods in an enclosed space, be sure that the convertible top is dry and that there is adequate ventilation.
 
Clean off bird droppings immediately, since they attack the convertible top and cause the rubber seals to swell due to their caustic characteristics.
 
Besides water, treat rubber seals only with talcum powder, rubber care products or silicone spray, particularly when they feel dry or tend to stick.
 
Eliminate noises such as squeaks with lubricant spray.
 
Depressions and discoloration may occur in the convertible top as a result of improper maintenance and cleaning or due to loading from excessive use. The convertible top and its seams may also develop leaks. These occurrences
are not covered by the warranty. For repairs, please consult your BMW center.
 
You can wash your BMW at an automatic car wash. Brushless systems are preferable.
 
If a brushless car wash is unavailable and a brush car wash must be used, modern systems with soft brushes are preferable. Do not select the wax finish option. The small amount of beading wax always used in automatic car washes will not harm your vehicle's finish.
 
In the case of more extensive dirt, which is definitely visible on lightcolored top materials, clean the top with the BMW Convertible Cleaning Set. Please proceed as follows:
 
Spray the convertible top with the cleaning agent and then rub with a well-dampened sponge using circular motions until a foam develops. Then you can finish washing the vehicle in an automatic car wash. After washing your vehicle 3 to 5 times, you should treat the convertible top with a special convertible top impregnating spray. Please follow the instructions on the spray can.

Thanks for the advice, everyone! Now, another question...
 
How are the BMW convertibles (3 series and/or Z4) in the snow? Ideally I will keep my 4wd pickup and get the convertible as well, but that may not be an option. I live near Chicago, so snow has to be a consideration. I'm concerned mainly about the RWD of course, but also about excessive cabin heat loss.
 
Thanks again!

Heat loss is no problem.. My 3-series is my wife's daily driver..Be sure to get heated seats... that will extend your top down driving by about ten degrees.. The one thing you will notice: Noise... Every car and truck next to you on the freeway will sound like it is buzzing in your ear (even with the top up)..
 
I can't really speak for snow buildup, as we haven't had more than an inch this year... but, the cars are designed as a 4-season car.. (ground clearance may be a problem in a Z4, in heavier snow). I have winter tires on mine (and on my previous 3-series sedan). I heartily recommend them...
 
As you can see from the BMW literature copied above.. a black top is much easier to keep clean and stain-free...
 
regards,
kyfdx

You will be pretty close to a six cylinder engine in either the Z3 or Z4. The cabin should stay pretty warm.
 
RWD in snow has issues but is manageable. Keep the traction control on and take it easy when accelerating.
 
If you are real concerned, you may want to get winter tires. If you have a truck, winter tires seem like an extravagance to me.

Keeping my Z clean by fastlanez4

New Z4 owner, what a car!
What is the best way to keep the flat black interior looking like new? Should I be using the car care equipment that BMW list in the book or use just plane water and very mild soap when needed?

Soft Top stains by avaughan

I have some pretty bad stains on my Z4 soft top. They're probably from a cat which took to sleeping on the roof for a while (unbeknown to me at the time). I'm having real trouble removing them - in fact no success at all. Any suggestions?

Time for service...CPU says 'No" by omegagen
Aug 14, 2007 (2:06 am)

I have a 2005 Z4 with about 6500 miles. I haven't had it serviced because the CPU says service isn't due until about 10000 miles. I've had the car since Oct. '05!
 
I know since most people don't drive these cars often I'm sure I'm not the only person who has encountered this issue.

My handbook recommends either to service at the mileage interval or every two years whichever comes sooner so it sounds like you're due a service in October! I've had mine four years and only serviced every two years with loe mileage and it's no problem.

I only put around 3k miles a year on my Z4, but I have the oil changed once a year. In fact BMW will cover the an annual oil change even if your not hitting your mileage.
