Soda Blasting Motorcycle Engine Fins

When I started trying to clean the cabinet with soda, it was a miserable failure. Soda is one-use and turns into powder after being used only once. The problem here was that when water gets on the soda it becomes white mud which could prove dangerous if not cleaned properly. This led me to an idea – instead of soda, what if I used a wire brush? Sure enough, problem solved!

The key here is getting the right combination and using it with caution. If you’re not technically inclined and cautious about your efforts, this process could make for a bad outcome rather than a good one. You need to plan ahead – both in terms of what you’ll use and how you’ll clean it up.

Don’t do this to your bike without the right mask for breathing, a spot mask will do just fine. Soda blasting dangerously sends aluminum particles into the air and hits you with them as well

Make sure that the engine fins are completely wet before you start. You don’t want to blast at dry fins because the soda won’t work as well and you might damage the engine in the process.

Put on your gloves, goggles, and mask so that you’re safe from any aluminum particles flying into your face. Blast away at the fins with your wire brush, making sure to get into all the nooks and crannies. You’ll be surprised at how much dirt and grime will come off with a little bit of effort!

When you’re finished, use a garden hose to rinse off the engine fins until all the soda is gone. Be careful not to blast water directly into the engine, as this could cause damage. Dry off the engine and you’re done!

Cleaning your motorcycle’s engine can seem daunting, but with the right tools and a bit of patience, it can be a relatively easy process. By following these simple steps, you can have your engine looking and running like new in no time!

How To Restore a Motorcycle Engine Case

Restoring your motorcycle engine is one of the simplest things you can do to make it stand out. There are many options that come with choosing how to shine up an engine, so below I will tell you about some different ways people have done this in order for them to get a shining result.
  • If you want to make your bike shine, here are the steps: first wash it thoroughly; then use rags and waxing cloths to apply pre-wax and buff out any grime or old wax. Then finish up by applying two coats of polish with all the same techniques as before. This is one tried-and-true way that will have anyone looking their best on this beautiful sunny day.
  • Cycle owners are now bringing their bikes to the local body shop, where they’re being spun in a machine that sprays an extremely hot combination of water and detergent. This method has become very popular because it’s so effective at removing all sorts of grime no matter how old or dirty your bike gets–from oil stains to rust marks! The one downside is this process can be expensive for those who don’t have much money lying around; however, if you want your silver shining like new again and gunk is gone without scrubbing too hard then this might just be worth every penny spent on it.
  • Recently, many people have been turning to sandblast their bikes. This process involves a machine that blasts sand onto the surface of your vehicle in order to strip off debris from an outdoor experience on it. The problem? It may damage or scratch surfaces depending on how close you are and exactly how it is taken off by hand once completed.
  • A dishwasher is a fantastic tool for cleaning your engine. Run the parts through some hot, high cycles and you’ll have almost as good of an effect as if they were cleaned by a technical machine.

How To Make A Dirt Bike Engine Look New

  • First, use your air compressor or can of compressed air to blast the dirt and dust from a few areas on the motorcycle engine.
  • Next, it is important to cover those sensitive areas of the engine that you don’t want to get wet. The fuse block and ignition coil are prime examples because they can cause major issues if submerged in water.
  • Using a citrus-based degreasing agent, spray liberally on the engine. Let it set for 15 to 30 minutes before removing and washing down with water and soap to complete your maintenance routine.
  • Next, take the water hose and a high-pressure spray nozzle to thoroughly rinse your engine. Make sure you’re removing all of that degreasing agent when rinsing it.
  • The engine is a tough one to maintain, so it’s important that you’re always cleaning the oil stains and other grime. You’ll want to use warm water with some soap in your bucket for easy scrubbing because dirt will stick around if left untreated.
  • Clean a motorcycle engine by taking the air compressor or compressed can and blow off excess water. Dry with old rags, towels to prevent corrosion of metal surfaces as well. Let it dry for 30 minutes before getting on the road again.
  • Apply the rubber seal protectant to your motorcycle’s hoses and fittings. This will both clean them and keep them from drying out.
  • Wash the chrome on your motorcycle engine with a clean, soft towel and chrome polish to make it look shiny. Buffing may take some time before you see results but keep at it until you get that high-gloss shine.
  • Take off the masking tape and plastic bags, that you have covered the sensitive component, please be careful not to damage any of those sensitive electronic components or parts on your engine.


How do you polish motorcycle fins?

To polish motorcycle fin wax, use a microfiber cloth, and rub it gently from one side to another. If the finish looks dull or scratched, apply a thin coat of clear nail polish first, then let dry completely. Make sure the bike is completely clean, and wipe down the handlebars also. Use an excellent quality polish recommended for polishing metal surfaces.

After 5 minutes, take off your gloves and place them in your handbag for later wiping. Take out a paper towel or a towel with some water on it, and soak up as much moisture as possible. Then, rub your fin using a microfiber cloth. Start by rubbing in the direction that will make the most sense when worn (the best way to wear bike parts is not always straight down). Continue this process until your fin looks smooth and shiny again.

If you want your fin to be extra-shiny, try applying a small amount of polish – you can buy this at any auto store or hardware store. Apply a very fine brush about 1/4 inch wide, and work it into the surface of your fin using very little pressure. You may need more than one application. Let the polish dry completely between applications. Do NOT wait overnight or it will harden. You can add additional coats if needed. This method works great for chrome rims and wheel barrels too!

If you’re having trouble finding a microfiber cloth (or are just lazy), you’ll find many options under kitchen towels in your local grocery store. 


A motorcycle engine can be quite difficult to maintain. However, if you combine the right cleaning products and techniques you’ll be able to make it look new again. Be sure to use a degreasing agent and then rinse it off with water. You can also use chrome polish on the engine to make it shine. Finally, be sure to cover any sensitive areas before starting the engine.
