Orient the jet in a manner that causes the water to slide off the surface instead of hitting the cloth directly. To ensure protection, it is recommended to use either Gtechnic Smart fabric or Renovo soft top cleaning. I have previously used Gtechnic on a Jaguar F-Type and found it to be really effective. However, it is crucial to promptly remove any drips on the car's paintwork, since the product solidifies into a clear varnish-like substance that becomes extremely hard to remove afterwards. Inquire as to the reason for my knowledge.
