First, motorcycle cleaning common problems.

1, riding to the car wash, the engine is still hot, a spray will smoke, at this time you can wash the car?

In principle, it is not recommended to wash hot cars. On the one hand, because the internal temperature of the engine is too high, rapid cooling may cause slight deformation of the metal components and oil seals, which will increase the probability of oil leakage over time.

On the other hand, if the engine is too hot, the spray may leave water spots on the surface of the metal parts, and the dispersed water vapor will also leave water droplets in the interior of the vehicle that is not easy to clean, causing rust.

What's more, you can get burned. I got burned by an F850 while washing a hot car. It was very painful.

If you want more authoritative proof that hot car washing is not good, I can only say that Honda and Harley have stressed on their official websites that they do not recommend hot car washing.

So in the premise of no hurry, or wait for the engine temperature to drop after the car wash safe, if you have a more important emergency, it is at will, such as the way to imitate rain with a small flow of water gun to help the engine to cool down, and then clean.

2, Can the high-pressure water gun wash the motorcycle?

This answer is the same as the hot car wash, in principle, it is not recommended, because most of the current high-pressure water guns are prepared for the car, but the engine harness and key parts of the car are protected in the cabin, will not easily be rushed to the water gun, so the selling point of the high-pressure water gun is usually the stronger the better, the stronger the water, the better, so the car wash is clean, can easily wash down the dirt.

But the motorcycle engine, all kinds of wiring harnesses and even plugs are exposed, although the manufacturer will also waterproof the wiring harnesses interface, but this can not stand the water gun strength, over time may lead to loose interfaces, and eventually poor contact, such as ABS coils, plus the wiring harnesses under the fuel tank.

Therefore, if you must use a high-pressure water gun to wash the car, it is recommended to reserve a gap of 3 to 5 meters between the water gun nozzle and the car, and manually intervene in the water gun pressure, so that the paint, line and parts of the motorcycle can be avoided as much as possible when washing the car.

3, motorcycle need special car wash liquid?

No need, some car cleaners on the market can also be used on motorcycles, such as XX car wash water wax, XX foam liquid, XX car wash water, the only thing to note is that you can not use car self-cleaning.

Self-cleaning is a very common cleaning agent in the car wash, the cleaning effect is very strong, in addition to car washing can also be used to clean the car engine compartment and tires.

The problem is that self-cleaning has strong corrosion on metal parts, and the motorcycle's shock absorber, calipers, upper and lower three stars, the engine, plus some decorative parts are made of metal materials, if you accidentally use self-cleaning motorcycle, the surface of metal parts will probably leave ugly scars, although it has no impact on safety, but it can ruin your good mood for the day.

4. Do the exhaust pipe and instrument need to be wrapped separately when washing the car?

No, I know that some motorcycle friends may worry that the waste water from the car wash will flow down the exhaust pipe into the engine, but the exhaust pipe has been reserved in the interior of the design at the beginning of the drainage hole, as long as you do not deliberately fill the exhaust pipe, or do not modify the whole section of the exhaust without holes, the engine will not be flooded.

The instrument is the same, normally waterproof, unless the waterproof layer is damaged, otherwise no special dressing is required.

Two, how to clean the motorcycle in the self-service car wash?

Since the self-service car wash, our main is a local adaptation, quick solution, like my nearby car wash shop is mainly used cheap detergent, the effect is general, win in cheap; But before washing the car, it is best to confirm the material of the cleaning agent with the owner of the car wash, if it is self-cleaning, then it is OK; Or you can also bring your own car wash wax + chain cleaner + chain brush, then we can be ready to wash the car.

According to the precautions mentioned above, first let the engine cool, then let the high pressure water gun away from the car, if you have softener/pre-wash, you can spray them on the car first, the main purpose is to soften the dirt, protect the paint, of course, it does not matter, such as my cheap car has not used pre-wash.

After that, we take a high-pressure water gun, spray the car at a distance, wash off the dust and impurities on the car, if you are ready to clean the chain, you can pull the distance of the water gun into the chain for a while.

Then scrub the body from top to bottom with your own/car wash cleaner, checking the rag for dirt and beware of sand scratching the finish.

Finally, clean the engine, wheel hub, and rear fork, because these areas are relatively less prone to scratches.

Then it is time to dry the body with a rag, and if possible, you can blow the body with an air gun to blow the remaining moisture down. At the same time, there are two things to pay attention to, first of all, to see if the screws of the whole car are loose, check frequently, to avoid the nuts running away from home, I have personally seen a number of domestic + big trade motorcycles have lost screws...

Secondly, it is necessary to check whether the engine and brake shock absorption have oil leakage/oil seepage, whether the tire pressure is normal, and check the capacity of oil + brake oil.
