Quick ? on prepping AR

Would grease lighting or purple power be ok to use for degreasing the rifle ? If it’s okay I would spray the rifle then wipe or spray it off with water then use a hair dryer to dry.

Thanks in advance.

Anyone ?

I dont know about the grease lighting or the purple power but I have just used the the sink with hot water and a nylon brush on a M&P and used a nail gun compressor to dry it off. It worked ok but its not my favorite method.
YMMV
