I clean and lube mine every 30 days, give or take a few, followed by a full line check. Gives me a chance to peel and pull the cutaway pad (actual practice instead of going through the motions) and flex the webbing. But then, i'm the type of guy who goes through the cutaway drill wherever i have a minute to spare and religously check my pins and handles.
