Regardless of whether you are thinking of prepping your car so that it can be made available to be purchased, get it clean preceding mechanical surgery; or simply would prefer not to wince when you open the hood, a bit of cleaning would improve things significantly. For both the cases, here are a few thoughts on how to clean aluminum auto parts.

Cleaning aluminum car parts

Carb cleaner

One of the ways to clean car parts that are made of cast aluminum is through a carb cleaner. You can use a carb cleaner on your vehicle and let it sit for a while. After that, use the bead or sand blasting technique with the machine. You can also use simple oven cleaners. Rub the liquid with a stiff brush and wash it off to remove all the grease. The oven cleaner does not have to be super expensive. The one at your home that you use on your own oven would work just fine on your vehicle as well. After rinsing the liquid away, for a better result, use sand or bead blasting, if the machine is readily available.

Sand or bead blasting

For those who do not know what sand blasting is or how it is done, sand blast cleaning or abrasive grit blasting is a surface treatment procedure generally utilized for different purposes. Abrasive blasting is a procedure by which an abrasive media is accelerated through a nozzle by methods of compacted air. The abrasive utilized differentiates given the required surface treatment. Blasting can strip paint off without harming the base material, regardless of the fact that it is plastic or wood, and smoothen out setting on even the hardest metals. The method's utility has reached to other home ventures as well, including stripping old bicycle casings and metal furniture, and expelling calcium stores from tiles. The operation utilizes pressurized air to shoot small bits of material out of a nozzle to take off the surface of an object. It resembles pressure washing just at low pressure, and with material that is significantly rougher than beads of water. Regular abrasives utilized include:

  • Steel shot
  • Glass bead
  • Aluminum oxide
  • Plastic
  • Corn cob
  • Ceramic grit
  • Steel grit
  • Pounded glass
  • Silicon carbide
  • Walnut shell
  • Baking soda
  • Copper slag

Bead blasting is used a lot when it comes to cleaning off auto parts. It is deemed, by many users, the best technique to get your car cleaner and brighter. Despite the fact that blasting can strip the chrome off an auto part, it is bad at expelling oil. Before you blast, insure that anything sticky or slick has been cleaned; else, you will wind up instantly fouling up the media you have just purchased.


Two of the degreasers that people have recommended a lot is Eagle One and Purple Power Cleaner. Both are acids. What you have to do with Purple Power is to spray it over the area which needs treatment, let it sit for a few minutes, and rinse it off with a hose.

When Eagle One is sprayed, it turns into foam. When that happens, wash the foam with water. It was made for cleaning unpleasant cast raw aluminum wheels but not recommended for painted surfaces. Once the liquid is rinsed off and dried, the aluminum is cleaner and brighter. There are many other cleaning agents available on the market that can help you get rid of the dirt and grease from your aluminum car parts. If you are using an alkali, be sure to treat the part with acid after it so that the material is neutralized and the chemical does not keep eating your vehicles parts. Wash everything with a lot of water.

Even though these cleaners and degreasers would start working when you spray them on your car, we would advise you to scrub it with a toothbrush or some other kind of brush or sponge. This gives a lot better result than simply applying the chemical and rinsing it away. Be sure to brush every nook and cranny for a shinier result.

It is best to begin with mild cleaners, and after that work your way up when they do not get all the dirt. For heavy cleaning of non-clear covered aluminum, use a wheel cleaner. Eagle One is a spray cleaner particularly for cast aluminum. The cleaners intended for use with clear covered wheels are not strong. NAPA additionally offers a genuine aluminum cleaner with notices everywhere throughout the splash bottle that it works truly well. However, you need to wear gloves and eye-protection.

Home remedies

Not only can you wash and clean your auto parts made of cast aluminum with heavy detergents and chemicals, but you can also use some ingredients that are available in your kitchen and clean up your parts.

One of the most efficient ways to clean up your vehicle made of cast iron is to wash it with a mixture of hot water and cream of tartar. Mix water and cream of tartar together and heat the solution. After the solution is hot enough, use it on the parts and scrub with a stiff brush. Rinse it off with water afterward after it has been sitting for a couple of minutes.
Using a mixture of lemon or vinegar with water and spraying it over the parts would also yield some results. Let the mixture sit for a while and then wash it off.

Aluminum conditioner

After you have cleaned up the grease or bead blasted your vehicle, you sometimes feel that the surface is not as smooth and shiny as it used to be. In this case, after washing the parts you can use aluminum conditioners. They are easily available on the market. Soak a washcloth with it and rub it gently over the car parts.
Sodium hydroxide

Sodium hydroxide takes the oxide off and is relatively safe to apply. It is harsh, not an acid, so it is better that you wear plastic gloves and a respirator in a ventilated region. The least demanding approach to clean aluminum is only splash or stream it on. You do not have to drench or plunge it. Give it a chance to sit around for 15 minutes at that point and hose it down truly well.

Hydrochloric acid

There is a way to make a splendid wheel cleaner with just HCl acid and water. Add three parts of water into one part of HCl acid. It works incredibly on eliminating aluminum decomposition. Take some Eastwood Metal Wash after the use of hydrochloric acid, and you can keep the corrosion under control sufficiently long to paint/powder coat the part.

Pressure washing

Cleaning an auto with a pressure washer is a suitable approach to keep a vehicle clean. Use the correct nozzle, pressure, and vehicle cleaning mixture to get the earth off. When washing your vehicle, it is vital to utilize a pressure washer with suitable power and water stream. The higher the PSI, the more forcefully the water will leave the tip of the machine. The more the GPM, the more water the machine will discharge. Pressure washers are significantly more efficient than hoses and utilize less water. You can buy both electric and gas pressure washers. Gas pressure washers have substantially more grounded cleaning limit and are excessively strong for light jobs, for example, washing a vehicle. Thus, in order to abstain from harming your vehicle, it is ideal to utilize an electric weight washer set at the fitting PSI. There are various distinctive sorts of nozzles to browse. Using the right size is imperative so that your vehicle is cleaned adequately and without harm to the paintwork. Narrower pressure washer tips reach less surface area, however, utilize more force. Wider tips cover more region, however, utilize less force.
