Don’t stuff around with cleaning rust off screws and bolts etc.., as the rust will return.
Replace with grade 316 stainless ( not grade 304 ) Permanent Solution !!
My cover screws on the EQ6-R mount rusted after 2 years of being permanently outdoors with just a cover. Replaced them 2 years ago with grade 316 stainless steel and they still look brand new.
Strangely enough all the other fixing hardware on the mount are still in fair to good condition.
I do externally lubricate my mount every 6 months with silicon spray which does protect it.
