Aluminate™ Case Study
An engine re-conditioning company was using a petroleum based solvent to clean their aluminum engine heads and blocks.
This was a labor intensive process, where the workers had to use a toothbrush to clean into the cracks and crevices.
Even with all this work, the aluminum surfaces did not come completely clean and still appeared to be discolored.
Therefore, the company decided to paint the engine parts to make them look better for sale.
The paint would improve the engine appearance prior to sale, but the paint would burn off quickly once the engine was back in use.
This company decided to give Aluminate™ a try.
Aluminate™ was able to clean the engine parts in a very short period of time without any manual labor.
The parts were soaked in the heated Aluminate™ bath for approximately 20 minutes at 180º F.
The parts came out much cleaner than the parts that were scrubbed using a solvent and a toothbrush.
In fact, the parts looked so good after the treatment with Aluminate™ that there was no need to add a coating of paint.
The re-conditioned engines were sold with their original aluminum surface, which retained its look after repeated usage.
The aluminum parts were cleaned faster, more thoroughly, and less expensively with Aluminate™ than with solvent cleaners and paint.
This manufacturer is now a dedicated and loyal user of Aluminate™.
How Aluminate Works
Immerse an item completely in Aluminate™ for 20 minutes at 140º F (60º C), checking the progress periodically.
Once the oxide is removed, simply rinse the item with water.
Aluminate™ can be used at higher temperatures, up to 180º F (82º C), to accelerate the oxide removal process.
At the higher temperature of 180º F, oil and grease will be removed, reducing the need for pre-cleaning with solvents.
When the oil and grease are removed at these higher temperatures, they will float to the top of the solution and can be easily removed by skimming the top.
Once the oil and grease are removed, the solution can be re-used.
There is a trade-off between the cleaning time and the energy cost required to maintain the higher temperature.
A temperature of 140º F provides the optimal balance between cleaning time and efficient energy usage.
Aluminate™ will not become active until it reaches a temperature of 120º F.
Since Aluminate™ requires a high temperature to work, there will be a dehydration effect from the heat.
Water may evaporate during the treatment, and the lost water should be replaced.
It is important to maintain the proper proportion of Aluminate™ to water.
The best way to do this is to mark the solution level prior to treatment.
If the level of the Aluminate™ drops below this level during the treatment, then water should be added to the mixture.
Once the oxide is removed and the treated item is taken out of the Aluminate™ bath, the item should be rinsed with water to remove all residual oxide molecules from the surface of the aluminum.
If the item is not rinsed, the oxide molecules will re-attach to the surface of the aluminum and cause more oxide to form.
In addition, there may be a dull finish on the aluminum surface.
Therefore, all items treated with Aluminate™ should be rinsed immediately following the treatment.
