Vinegar is good for dissolving the crap. I use the white vinegar and spray it in with one of those pump action plant sprayers, you know the ones that you can pressurise with the plunger on the top. Cost next to nothing from a garden centre. The Scotoiler 365 is very effective at stopping corrosion.
