Cleaning Jupiter32 Shielded GPS Modules

Has anybody any experience in cleaning the Jupiter 32 LGA in a Aqueous cleaning process (or any kind of shielded GPS Module). The manufacture does not recommend Aqueous cleaning because that length of drying time and that this may leave residue on the interior of the shield. There is a micro BGA inside. To eliminate this risk we install the LGA GPS module with a hot air unit after cleaning. Has any one cleaned these Shielded GPS LGA Modules in an Aqueous process?
