What cleaner/lube to use for new AR

[Klem]

I have been using WD40 for years to clean guns. A good spray and then stand it upright on a paper towel so gravity helps get rid of it. then wipe it dry with more paper towels. It strips out all the soot and carbon especially when using suppressors. Once dry with paper towels I lube moving parts with Sweets gun oil (it contains wax to keep the oil on surfaces for longer). I don't clean barrels as much as I used to but when that happens I use Butch's bore shine to start and WD40 to clear it all out. If it's going into storage I use oil instead of WD40.

I understand WD40 leaves a varnish when it dries but it's never damaged any of my guns. So to be clear, WD40 for cleaning and rust prevention only. Oil for lubrication.

I've also used Remington oil in the spray can but found it dries out too quickly.
