Any good tricks for this?

For knives I've used an application of White Lightning, allowing it to harden, then running under hot water to remove the White Lightning and the gunk collected in it. I would then use a hair dryer to completely dry the blade out, re-lube and be good to go.

The pivot seems to be a tad more loose on razors so wondered if that would work or if it is easier to just use something like dental floss or ???
