I have seen lots of how to clean my camera, lenses, sensor threads, but never one on cleaning a tripod. My ballhead, and tripod legs have gotten very sticky recently so it was time for a good cleaning.
After a little research on the web, I tore my tripod apart and cleaned it all up. Here is what I did.
For the ballhead (Manfrotto 488RC2) I started by taking it completely off of the tripod. I took a clean rag and sprayed some WD40 onto it. Onto the rag, not the head. I took the damp rag and wiped off the ball as much as I could. It helped, but not as much as I would have liked. My next step was to unscrew the bottom of the ballhead. Once that was out, I took a snap-ring pliers and removed the retaining clip that holds the screw that I just unscrewed the base of the ballhead from. Below that was another retailing clip that holds in the main part of the ballhead that tightens against the ball to keep it from moving. I removed that with the snap -ring pliers and took the guts out of the ballhead. Be careful that you don't loose any of the parts. There are only about 5 parts to this so it was easy to keep track of them. Once I had the guts out, I found a small metal shaving that didn't belong there, so I removed that.
I took my damp WD40 rag, and wiped everything down. This not only acts as a lubricant, it also helps to remove any dust and small metal particles. I read on the web not to use any heavier lubricants as they will hold onto dust as it finds it's way into the ballhead and make things worse. Wipe off any excess WD40.
The legs (Manfrotto 3021 BPro)were also very sticky, and full of dust. I uses a philips head screwdriver to loosen the clamps on the legs, and pulled them apart one by one. Again I took my rag with WD40 and wiped down all of the legs. To clean the inside of the legs, I took my rag (old sock) and put it over a piece of pipe I had laying around in the garage. I then used that to clean the inside of the legs like you would clean the barrel of a gun. Once done, I reassembled the legs and wiped everything down one last time.
My final step was to set the tripod outside to dry out, and air out.
Your steps may very a bit depending on your tripod and head, but I'm sure the general idea is the same.
