Paint doesn't stand a chance against a desulfator treatment. The desulfator "kicks" 50+ amp electrical pulses thru the painted object several hundred times per second. If you want to investigate paint stripping by electrolysis, hook up a battery desulfator to the electrolysis bath. The only resistance to lifting the paint film I have encountered is when acid etch primers are used successfully in chemically bonding the primer to the metal surface. Given that paint is not an insulator at the atomic level, if you have enough patience to allow several days of exposure of your painted part to the electrolysis process, paint film pigment carriers will be broken at their interface with the metal piece and the paint will fall off the part in sheets.

"Rust" is neutralized in nearly every pock mark, crevice and crack on the surface of the item in the bath. The cleaning comes at the expense of uneven loss and pitting of the aluminum electrode (your engine head).Įlectrolysis as paint stripping process? Electrolysis results in derusting at an atomic level, that is why it works as effectively as it does.

The destruction is not equal across the entire piece of aluminum and coked up areas will clean slower than non coked areas. In backyard terms, yes, the aluminum is being "cleaned". The fact the surface of the aluminum is being consumed, by default will release any material clinging to the surface of the released aluminum. Any energy applied to the anode / cathode elements in the bath with a voltage applied in excess of 1 - 2 volts DC will break apart the oxygen / hydrogen bonds in the water bath the electrodes are in contact with.Try hooking a 1.5 volt AA cell up to a small electrolysis setup - you will see voltages at this level support the process, albeit much slower than a 12 volt battery charger.Īluminum can be used as an electrode but will suffer much faster "erosion" than iron. In backyard mechanics terms, the electrolysis process steals "extra" oxygen from "rust" so the rust no longer has an overabundance of oxygen which can be used to combine with additional iron to form additional rust.Ĭlean iron electrodes will still allow electrolysis to occur. The fact rusty iron "derusts" when used as a cathode material is just a happy consequence of using rusty iron as the interface material in the electrolysis bath.

A similar mistake would be defining driving your car behind a gravel truck as a "paint striping process", although that would be one result of such an activity. Electrolysis is not defined as the process of derusting or cleaning metal.
