Any highly alkaline cleaner has the potential to dry out soft surfaces, but don't overthink it. Unless you're using it very frequently and applying no dressing or protectant, I see no reason for concern. I do an engine cleaning yearly on my 30 year-old El Camino using Citrus diluted to 1:4 and have never noticed a problem, even though most of the plastic and rubber parts are just as old as the car.
