Are the wiper seals on suspension forks resistant to mineral oil? Out of what material are those seals made? Feels like silicone to me. I am tempted to try Ballistol, which I have in considerable quantities since I clean my firearms and bikes with it. I would wipe the stanchions before every ride and apply one small drop of lube to each wiper seal. From the Ballistol website:
Ballistol will not negatively affect plastic materials or paints which are chemically resistant to oils. Specifically, Ballistol will not adversely affect PVC, high pressure Polyethylenes, mipolam, teflon-derivatives or hostaflon-derivatives... As a rule of thumb, it may be safely assumed that all plastic materials, polymers, paints, lacquers, or varnishes that are chemically neutral toward technical oils will not be adversely affect by Ballistol either. The same holds true of rubber objects. All those types of rubber, which are chemically resistant against mineral oils, will also remain unaffected by Ballistol. Rubbers that are not resistant against mineral oils may become brittle if exposed to Ballistol for an extended period of time and/or under higher than ambient temperatures. If applied thinly Ballistol is suitable for maintaining and cleaning any sort of rubber without damage.
