Ive used oven cleaner before and the foam sticks to the surface while doing its job

Get yourself a bottle of CLR and you won't use anything every again.
We use it on all the rotary engines we rebuild.

I use 50:50 mix of kero and degreaser, cleans well and rinses off with water. I rinse it off into my enviromentaly friendly oil/water seperator.

Don't use the water based Supercheap degreaser in a steel parts washer, it rusts them out.

That clr stuff is fantastic for just about any thing there's also a simple green product for parts washers http://australia.simplegreen.com/au_pro ... industrial it used to be on that tvsn channel but I have seen simple green stuff down at bunnings

Supercheap sell parts washer solvent in 5L containers located in the car cleaning area at the end of the aisle at Blacktown it's there sca brand

Yeah that's the stuff they recomend for their parts washers, then 12 months down the track it's full of rust holes.

I don't like to use the aqueous based stuff for this reason. And also I usually wash with an eye to painting not long after it has dried, or for storage. Hence the bias towards dead dinosaur hydrocarbons... This is also in a degreasing bath as well. Worth their weight in gold.
