I like Rock and Roll Gold too. Works a charm and the chain generally stays pretty clean. Only problem is that you use alot if you apply it as per manufacturers instructions.
I use a heat gun on the chain to boil out the kero and water (I rinse after kero). Non o-ring chains (i.e. all bicycle chains) are made only of steel so the heat gun (300 deg C or so at most) doesn’t harm them. When the chain sizzles you’re doing it right.
I’ve always found this a good technique. Doesn’t work so well on geared bikes however.
