The old standby Gunk Engine Brite #EB1 is good stuff if horribly toxic .

It will also kill off any grass / plant life so mind the run off .

When first you begin it's great to soften up the deep & thick gooey sludge up underneath the manifolds and block, once you've cleaned it well I find the purple stuff works just as well and is far cheaper .

Oven cleaners do work well but some have chemicals that will attack your alloy parts and plastic plus give you skin burns .
