Most of our tripods look like they are out of the ark! They're good quality sturdy ones but they're all completely rust coloured and look a mess. I've ordered a load of new ones to replace them but it seems a shame to throw them away when you are good quality. I hammerited all the old bunsens but obviously can't do that with the tripods as they will be heated. Any one with any eureka ideas as to how to rejuvenate them?
