How should these triggers be cleaned and how often?
As others have stated, lighter fluid works well and then a good blast with high pressure air. It's even better if you're comfy with removal, then clean the individual pieces.. A set of slave pins really helps with reassembly.
NONE.
I have used Remington 700s for years with no problems but I'm a little nervous about it.
I clean mine every time I clean the rifle - which is EVERY time I'm done shooting it; whether it was a shot or three or if it was at the end of a long P-dog day..
If you don't have a bore guide, just clean the rifle with the action out of the stock and placed trigger-up. Then carefully swab out/blow out any residual cleaning fluid that might be left over in/around the chamber area before putting it back in the stock..
While it's in that position, make certain you note full and
easy trigger movement in both directions.. If there's ANY (repeat ANY) hesitation in its full return to the set position it's time to start over.. Or - replace it..
FWIW.
