In the field of car maintenance, “revolutionary” technologies periodically appear, which over time, if not harmful, then turn out to be in little demand. Portal “AutoVzglyad” tells about one of them.

We are talking about the so-called steam washing. The adherents of this method claim that the steam itself penetrates the “dirt structure” and peels it off all surfaces and from the most hidden nooks and crannies. And they promise a guaranteed result when washing everything: body, engine compartment, car interior. The essence of the method is as follows: in a special device-steam generator, water is heated to 120ºС and the resulting steam under a pressure of about 8 atmospheres is sent through a hose with a nozzle to the surface to be cleaned.

As for washing the cabin with steam, then there are no special questions. Do we use a steam iron when ironing clothes? This means that nothing bad should happen to fabric and leather upholstery due to steam. But there are doubts about the safe effect on the paintwork.

Yet 120º is not quite the temperature for which car paint is designed. It is possible that immediately after “stripping” it will not fall off the body. But such local overheating, of course, will not extend its service life. It is especially worth considering the advisability of “ferrying” the car in winter. When a heat of 120 degrees suddenly “piles up” on the paintwork, still chained by street frost, common sense suggests that it will not be possible to avoid the formation of many microcracks.

When it comes to steam washing the engine compartment, supporters point out that unlike the Karcher’s water jet, the jet cannot damage anything under the hood. Let’s start with the fact that a normal engine does not need a sink in principle. It works great both in dusty form and shiny with perfect cleanliness.

Steam is the same water, just in a different state of matter. It condenses on the surfaces of the engine compartment and, as with washing with the usual water jet, can penetrate insufficiently sealed electrical connections. Which, for example, leads to problems starting and running the engine, electrical “malfunctions” and similar possible consequences of washing the engine in any way.

Superheated steam, unlike water, with its high temperature also attacks all types of plastic and rubber under the hood. This, for example, can break the plastic insulation of the elements of the same electrics. And then the condensate will complete the dirty work begun by overheating. In rubber products, elevated temperatures can cause accelerated “aging”. Do you need all this? If not, it is better not to steam wash the engine.

But if you really feel like cleaning, do it using good old chemistry and a gentle spray of water – preheat the engine, then give the engine bay at least an hour to dry completely.
