There are several things you may remember from school and growing up one is that if momma put a tea kettle on the stove the mist you saw coming out it when it whistled was HOT! Remember those science experiments where you heated a crushed can with a little bit or water in it popped back into shape and started to swell up larger? You remember hearing use hot water to wash your hands, dishes, or clothing and use some soap well these things all have something to do with our latest service Vapor blasting also known as vapor or steam cleaning. Cleaned by Pete has purchased two units to add to our cleaning arsenal of tools.What do I use vapor or steam cleaning for? Patio furniture, greasy motors, greasy equipment, motorcycles, stoves, shopping karts, playground equipment, kitchen and butchering items, while used mostly in the auto and manufacturing areas vapor cleaning is gaining a whole new life in the USA. Vapor cleaning in Europe and Australia has been going on and being refined for some time now during the '60's steam cleaning was loosing a battle to the pressure or power washer here in the States. Back then it seemed we had unlimited water, gasoline and diesel fuel all of which you would need to run a heated power washer, but in other countries they were already starting to conserve and look ahead. Vapor or steam cleaning is more efficient way to clean in a lot circumstances. Call us with any questions.
Secondly it reduce or eliminate splash back in your shop or area in which we clean and onto the operator compared to hot water pressure washers. It is easier to clean or degrease the item we are working on. Doing research for this venture we talked to several "old timers" in fields from mechanics, heavy equipment, industrial, machine shops and general auto shops. One thing that they all agreed on was that there was a place for hot high-pressure cleaning but nothing beat the power, efficiency and lack of mess that steam / vapor cleaning had, also the advantage of disinfecting with live steam is one of the best ways to kill bacteria.
Below is some information of why these steam or vapors cleaners work.
Vapor Expansion is why steam cleaning works heating water up way over 214 degrees plus in one self-contained cleaning machine at low pressures between 80 to 200 psi. Pressure affects the point at which water boils or vaporizes into steam. At a pressure lower than the pressure of the atmosphere at sea level water boils at a temperature lower the 212°F boiling point of water at sea level. At pressures higher than the pressure of the atmosphere at sea level, water boils or vaporizes at temperatures higher than 212°F. a pressure washer operation the pump simply pushes water out of a restrictive nozzle. The narrow passage through the nozzle increases the water's velocity and, consequently, its potential impact and cleaning power. In pressure washing, the pressure or restrictive nozzle is the last part of the machine the water flow passes through. In simpler terms these units put out steam more like a whistling tea kettle in stead of super hot water out of your kitchen faucet at full blast. The steam cleaner doesn't so much use steam to clean as it uses steam expansion to propel water at near its boiling point at a high velocity. The closer the steam cleaner's nozzle is to the surface to be cleaned, the higher the temperature and velocity of the water, the more effective the cleaning action. In addition to steam our vapor cleaners have a feature that we can add soap or cleaning solutions directly in to the cleaning stream the biggest advantage to this is that heat will help any soap or chemicals work more effectively this also reduces any "chemical runoff" to a smaller factor. The expanding and cooling of the water when the water passes through the special nozzle puts the vapor additional pressurization and cannot remain a liquid at ambient temperature. The water cools itself to 212°F by vaporizing a portion of its volume. This is called "flashing to steam." Depending on the system, from 5 to 15 percent of the volume vaporizes, cooling the remaining liquid. This steam vapor, with a properly designed steam cleaning nozzle, also propels the remaining water droplets. Unlike a pressure washer nozzle, where the restrictive orifice is the last thing the water passes through before reaching the atmosphere, the steam cleaning nozzle has an expansion nozzle placed past the pressure orifice. This directs the water vapor energy rather than allowing it to dissipate in all directions. When water vaporizes, it expands to almost 1500 times its former volume. This expansion, directed by the somewhat conical steam nozzle, adds velocity to the water droplets. So, not only does the expansion nozzle direct the steam cleaner's output, it serves as a sort of propulsion chamber. No simply the super heated water hits the air out side the small hole in the nozzle and becomes steam it more or less expands or flashes becoming like a small explosion and these small drops or hot water hit the surface and tumble and splat to chip a way the dirt or grease, it in the same process kills germs and bacteria.
We will still offer "Hot or cold water power / pressure washing" along with our graffiti removal, sidewalk and gum cleaning, wet sandblasting, wet soda-blasting, exterior house-washing, and all our other service. If you have any questions please call us 1-417-459-7869, as always thank you for your support.
