A litle too rough to go out today so I thought I'd clean up the equipment some. I have 3 purge valves on my bc. To get them open for cleaning do I just use some elbow grease and turn in couter-clockwise direction ? Once open would it be worthwhile to spray springs with silicone ? I was planning on mixing up some soapy water ( joy ) and giving the bladder a good rinse. Any other ideas, caveats ? Thanks.
