Cleaning drum brakes with ABS

Would like to clean up 93 GC rear drum brakes by spraying with brake solvent. It has the ABS wheel speed sensors. Do I have to remove them or try not to spray too much on them?
Thanks in advance!

If you are using a product made for cleaning brakes, you will not have to worry about the sensor.

It is one of the safest cleaners for most materials.

just dry the surfaces with a rag or blow dry with low pressure compressed air.
