Bicycle pump slips after using gear oil My pump got little rusty from rain. So i tried gear oil on it. But now its not pumping, just sliping all the way down. Is it because of oil or the valve is damaged? I tried removing the oil with detergent. But its not working.
I have found that cleaning the internals, and light lubrication with a light silicon grease works wonders. Silicon won't hurt the rubber
