There are two types of car washing methods: water wash car wash, which uses only water to clean the car, and shampoo car wash, which uses foam on a sponge to wash the car.

With a foam car wash, the dirt is lifted up by the foam, making it easier to remove the dirt than when washing with water only. It also acts as a cushion for the sponge and paint surface. “Foam” is important not only for detergency but also for body and sponge lubrication.

Even if you rub it gently by hand, you can’t get rid of the car wash scratches due to the friction between the sponge and the painted surface. However, with the cushioning material called “foam”, the risk of car wash scratches is reduced.

Cars with glass coatings can be cleaned with just water, but the foam cushions do not damage the coating film, and the protective effect can be maintained for a long time.

merit

Foaming car wash makes it easier to remove dirt by lifting dirt with bubbles. In addition, since dirt is wrapped in foam, it prevents dirt from adhering again.

In the case of washing with water, the number of tools is small, but close attention is required to prevent dirt and scratches.

how to make bubbles

How to make bubbles with a bucket

  • put car shampoo in bucket
  • Increase the water pressure and pour the water with the hose as close as possible to the bucket

When the foam becomes less, stir it by hand to create foam, or add water at maximum water pressure to create foam again.

How to make bubbles with a car wash sponge

Some car shampoos do not use a bucket to lather, but instead take the car wash sponge directly and rub it to create a lather.

In that case, soak the car wash sponge in water well in advance, apply plenty of car shampoo, and rub it to create foam. Check the contents of the car shampoo to see if you should lather it in a bucket or take it directly into the car wash sponge.

A car wash foam gun is a convenient car wash item that can spray water and detergent at the same time by equipping a hose. In general, the image of a shampoo car wash is to lather the detergent in a bucket and wash it with a sponge. On the other hand, car washing using a car wash foam gun is attractive because it can be easily washed at home by spraying dense foam that is as good as a car wash machine.

Benefits of using a car wash foam gun

The advantage of using a car wash foam gun is that it can significantly reduce the time required for car washing. It also minimizes the need to use sponges.

As a result, you can prevent scratches caused by scrubbing, and you can easily remove dirt from places that are difficult to remove with a sponge, such as under the body and roof, with the power of water pressure.

In addition, unlike a car wash at a gas station, you only need to purchase a foam gun and detergent, so you can maintain your car economically.

How to choose a car wash foam gun and points

A type that can be sprayed with only water is recommended.

If you want to keep your car clean with a car wash foam gun on a regular basis, we recommend a product that can be sprayed with water only. The foam gun is added to the combination of tap water, detergent, and hose that are usually used for car washing, and no complicated preparation is required, so even beginners can introduce it with a low hurdle.

However, be aware that the water pressure may not be enough, and the water will dilute the detergent, so you may end up using more detergent.

Type to connect air compressor if you want to remove dirt firmly

If you want to thoroughly remove dirt, we recommend the type that connects an air compressor to the foam gun. The same type sprays a mixture of water and detergent in a tank with high pressure from a compressor.

Not only does the high water pressure work hard on dirt, but it also allows the mousse-like dense foam to spread evenly over the vehicle.

Unlike the tap water direct connection type, it takes time to prepare the mixed liquid, and it is necessary to purchase an air compressor and high pressure washer separately, so please understand that the hurdles for introduction are higher.

It is convenient if the concentration of foam can be adjusted at hand

For the tap water direct connection type, which tends to increase the amount of detergent consumed, we especially recommend the type that allows you to adjust the concentration of the foam with a dial at hand. Depending on the adjustment level, you can freely change the mixing ratio between the pumped detergent solution and the water coming in via the hose. It is economical and convenient because you can flexibly decide the minimum amount of detergent required for car washing.

Car wash procedure when using a car wash foam gun

1. Rinse away dust and debris with water only

In preparation for the car wash, lightly rinse the car body with water only. Even if you wash your car with a car wash foam gun that does not require wiping, if dust and debris remain on the car wash, it will cause scratches. At this stage, you don’t need to wipe off the water after flushing.

In addition, it is better to avoid places and times when the sun is strong because the foam sprayed on the car dries quickly.

2. Remove dirt with detergent + water

Next, the dirt on the car body is removed by simultaneously spraying detergent and water with a foam gun. If you can adjust the spraying force, first loosen the dirt with a weaker spray, and then increase the momentum to remove the dirt. As for the order of spraying, starting with the roof at the highest position and gradually lowering it will make it easier for the dirt to drip down together with the water, making it more efficient.

3. Rinse off foam with water only

Once the foam has spread all over the vehicle and all the dirt has been removed, wash off the foam again with just water. As in step 2, pouring from a high position on the car body will increase work efficiency.

For finishing, use a highly absorbent towel or microfiber cloth to blow up the moisture so that no water stains or unevenness remain. Be careful as water is also entering the edge of the hood and trunk.
