According to the last census (2010) in Russia, 26% of the population lives in rural areas. This is more than 37 million people. These Russians have many cars, but few or no car washes or the means to visit them. The situation is similar in small towns. Most of these car owners prefer to wash their steel horses with a non-contact high-pressure washer like "Korcher".
With this washing option, the paintwork of the car body is not damaged. And the body is about half the cost of the car. Another reason for the use of this modern technology is the small amount of water consumed. A car can be washed with almost two buckets of water.
About factory blowers
If a car enthusiast bought a branded car wash for 8,000-40,000 rubles, then a high-quality foam generator will almost certainly be in the box with it. The cost of such a foaming agent is 1600-2000 rubles (independing on the model). Compatibility with sinks from other manufacturers is not guaranteed. In a set of cheap car washes for 3000-8000 rubles, there is also (purely nominally) a foam generator, but of such quality and such performance that after the first attempt to use them for their intended purpose, these devices are simply thrown away due to complete unsuitability. In the store, such a "dummy" steam generator costs 500-700 rubles.
Why lather shampoo?
This article is intended for owners of pressure washers that did not come with effective foam generators. It is known that dense and plentiful foam with the use of a special shampoo, applied to a dry body, significantly improves the quality of its washing.
An important parameter when washing is the time of exposure of the foam to the dirt: if you wash off the shampoo too early, it will not have time to react and the dirt will not be completely removed. If the foam is overexposed, then the dirt that has passed into the foam, when the composition dries, will again fall on the body in the form of a whitish precipitate, which will inevitably lead to the formation of ugly stains. Therefore, the foam should be on the surface of the body paint for about 4-5 minutes.
Taking into account the above, motorists are trying to make a foaming agent for washing with their own hands. Some of them are eyeing large and expensive garden sprayers, spray guns that, after rework, can theoretically be used to spray shampoo, but the cost of suchdevices and necessary air compressors, as well as other spare parts and components, often exceed the cost of a branded pressure washer.
From what and how to make a do-it-yourself foaming agent for washing?
Consider the cheapest and simplest option, which has proven itself well with many car owners. So, we make a foaming agent for washing with our own hands from a sprayer. We take an ordinary cheap manual garden sprayer, which looks something like the picture above, and consists of a pump, a container with a volume of 0.75 to 2 liters and a nozzle.
Its special nozzle allows you to spray the solution and adjust the spray pattern, but such a device will not create foam. Similar sprayers from different manufacturers have differences in size and design, so in the article we will consider the idea of rework. Specifying specific dimensions is pointless.
Sprayer - almost ready foam generator
The do-it-yourself foamer drawings are very simple and easy. A slight refinement will allow the use of a store atomizer. To do this, unscrew the plastic tip of the nozzle and place 2-3 cubic meters inside. see foam rubber, glass wool, foam tablet or the material of an ordinary metal grater, which is used to wash dishes. The volume of these foaming elements is selected empirically. In the upper part of the solution supply tube, a hole with a diameter of 0.3-0.5 mm should be made with a needle to mix the liquid with air.
Upgrading the do-it-yourself foaming agent for washing with your own hands to increase foam
The specified device can be upgraded to increase the volume of foam. Instead of a regular nozzle, a new nozzle can be made from two syringes with a volume of 5 mm. It is necessary to cut off about half of its length from one syringe, select the diameter of the washer or cut off a part of a cylindrical plastic tube from the standard nozzle for attaching a new nozzle to the sprayer.
After that, it is necessary to connect the cut-off part and two syringes in any way, after placing the foaming material inside, which is indicated above. It should be closer to the sprayer outlet. The tip of the syringe must be left empty to control foam agitation.
If it is possible to purchase nozzles F110 (015, 02, 03, 04, 05) or flat jet tips like HYPRO F80-06, then you need to cut off the extreme part of our homemade nozzle and install a flat jet tip as a nozzle. By changing the tips, you can achieve the desired spray pattern.
The air pressure required for such a foam generator can be created with a foot pump by installing a tubeless nipple on top of the tank. The tank should be pumped up with a pump without fanaticism, no more than 4 atmospheres, otherwise the spray tank will burst. Some sprayer models have a bypass valve. It needs to be adjusted to a pressure of 3.5-4 atmospheres.
After washing, do not forget to treat the body with liquid wax, as its varnish coating has a porous structure. These pores must be closed, blocking the path of corrosion. It is not difficult to make such a foaming agent for washing with your own hands from a sprayer. It works for many motorists and suits them completely. The cost of such a device consists of the cost of the atomizer itself, a pair of syringes, a car tire nipple and is 300-400 rubles.
