[calgarydetail]

I use auto wash for engines, wheels (when not bad) and for a pre soak of either really bad cars or when im doing a full detail.
It will strip wax but depending on what your doing after the wash it may not be a big issue.
I have a 5 litre hand pump chemical spray. I fput 1 litre of wash in it thene full with water. I just pump and spray. It work really well for gettig the little nooks and cranys in the engine compartment
