BigTriangle At $1.29 a 400g can it's cheap, and I've de greased my engine with it today, it works OK. http://www.supercheapauto.com.au/Product/Export-Degreaser-400g/1196
Ex850R Their 10lt or 20 Lt drums of ready to use is good, put in your own spray bottle, a garden pressure pump pack
BigTriangle The stuff I'm using, I haven't even looked to see what it does besides take caked on gunk off.
egads familyman;c-142830 wroteAnyone know of a degreaser that doesn't leave those 'streaks' on paint or mark aluminium? You would need to find something ph neutral as both of those are effects of it being a strong base
bigal I find this stuff excellent apart from the cost. Safe on plastic. I haven't noticed any streaks on things but not saying it doesn't leave any. http://www.supercheapauto.com.au/Product/3-in-1-Degreaser-400g/104990
Essbos Ive always found a 10:1 dilution of ct18 truck wash in a spray bottle works well on aluminium.
