Phase 1 was the initial power wash.
We went over the entire car in Phase 1 with a power washer without soap or any degreaser; just good old water. The results were remarkable, but remember this car has not been on the road since 1981. However, it was driven from 1969 until parked in 1981. That is still 12 years of regular everyday usage.
Phase 2 is all about the “Oven Cleaner” Challenge.
The second power wash of the engine bay and underside was preceded by a liberal application of oven cleaner. We purchased 4 cans for the cleanup on our AMX. We used two cans of the expensive Easy Off and two cans of some generic oven cleaner that costs one third the price of Easy Off. We sprayed one half the underside with one and one half with the other using the drive shaft tunnel as the dividing line. Before I give the results away check out the photos below.
We spayed anything that hinted of grease or oil.
Since the engine bay is also going to be completely repainted we were not worried about the oven cleaner damaging the paint. We let ours sit overnight before the second pressure wash and the oven cleaner worked as a fair paint remover. Warning, if you care about the paint use sparingly.
We really laid it on under the car. Surprisingly, there was not a large amount of oil and grease under the car but we are going to get rid of all of it.
The differential was probably the dirtiest part of the entire car so we really soaked it down.
Some of what you see under the car is not grease and dirt but factory applied undercoating. You can tell the difference because the undercoating is rock hard, we have no intention of removing it.
This is the underside of the front suspension. It cleaned up great.
From this distance, everything looks almost new!
Little more than a scuffing should be necessary to paint these items.
The original color of the car was white and we even got down to the original paint on the uni-body frame. They must have painted this area black when the car was repainted red.
Here is where you can tell the obvious line between undercoating and the bare metal.
The differential cleaned up real well but we will go back over it with a second coat of oven cleaner.
Can you believe how well this cleaned up?
Remember, this is pressure wash, oven cleaner and NO steam or degreaser.
Ok, we are going back with one more application of oven cleaner to hit a couple of heavy grease spots that didn’t come completely clean in one application. We used a total of 3 cans of oven cleaner up to this point. Although this was not a scientific test we could not notice any difference between the two. My recommendation; buy the cheap oven cleaner and leave the Easy Off on the shelf.
