Has anyone used WD40 Specialist Degreaser for cleaning guns?

I am using regular WD40 to flash out dirt after using CLP / brushing off gun parts.  WD40 spray aids with removing it from hard to reach spots, i.e. from inside of the Pardini SP22/HP32 frames.  I wonder if degreaser would provide with additional effect, but not sure if it is safe for all surfaces.

Thanks,

There's a Slip 2000 degreaser that the local PD armorers use, it's not cheap and I'm told it's a good cleaner but to oil up after use.

Anyone else try it?
