Move along very fast, you will save time, but you will not clean and sanitize as effectively. Move slower, the heat stays there longer, and you have a much better case of killing anything and cleaning better. And the rate of speed at which you move along the surface will make a HUGE difference. It stays hotter and cleans far more effectively than just spraying steam on a surface from far away. You have trapped the heat and not let it escape as easily. NOW try touching a microfiber pad that has just been cycled on for 20 seconds or more. By using a cloth or pad over a brush, this will trap the heat even more. By using a brush, you can trap the steam on, or into, the surface and retain far more heat. The brush and gentle (or aggressive in some cases) scrubbing action will get you there way faster than just spraying steam and expecting built-up grime and dirt to magically go away. But a brush gives you a much better chance. To be the most successful in steam cleaning, it is really about technique.Ī better way in almost all cases is to use a brush on the nozzle. But this is also debatable in how long steam needs to be applied to kill the virus on the surface. And to sanitize, it needs to be there for at least a few seconds. The steam needs to be applied directly on the surface and not allowed to escape. But that method is not the best cleaning technique. Spraying steam all overlooks really cool and puts on a good show. This is actually a very wrong technique in cleaning. This is why the “test” that a customer will do when they hold their hand 5 inches away and spray steam that they say it’s not that hot. now it’s about technique and knowing how fast steam will cool as it exits the nozzle. It still is pretty hot, but how hot at that point? Can it still disinfect a surface if held 2, 3, or 4 inches away?īut if we estimate the steam is still at about 250 degrees on exit, exactly at the tip of the wand, it still will seem its plenty hot to kill a germ, bacteria, or a virus. If the steam wand is held even a few inches from a surface, it has cooled even more from hitting the atmosphere. This is directly at the tip of the wand, and after the steam hose has been “primed” and only hot steam is escaping. We estimate about a 50-degree drop by the time it exits. But the steam then needs to escape the boiler and rush through an empty and cool hose. On our Chief Steamer 75, it will be about 310 for argument sake at 85 PSI. Why would it feel only warm, and why can you stand the heat? The reasons are numerous. The customer is spraying steam on their hands, and they can actually handle the heat. When I hear that, I know EXACTLY what they are doing. Many customers, when they first receive their steamer (regardless of the model), will question that the steam is not that hot. It matters greatly how you do it if you want to have a chance at this. Here is where the very grey area comes in. Sounds like enough, right? Just blast any surface with a little of this superheated steam, and ZAP….virus, germs, and bacteria are all gone! On our Chief Steamer 75 commercial machine, we are at 85 PSI in the boiler, and that equates to roughly 310 degrees of superheated water inside the boiler. And the higher the pressure the steamer can reach, the higher the temperature will be. Many steamers, even the less expensive, non-commercial ones, can produce steam at close to 250 degrees. To produce steam, we have to go far above the boiling point of water (212 degrees), so wouldn’t it make sense that steam can kill a virus? And boiling water is generally very effective in killing off most bacteria in foods.
That is why it’s important to refrigerate food and cook at high temps. Many say that germs thrive in temperature environments between 40-140 degrees Fahrenheit. Many scientists will tell you that high temperatures can kill germs. But getting back to disinfection and killing of a virus……. Steam has become a preferred method of cleaning for many businesses and homeowners alike. It’s fast there are no chemicals used the degree of “clean” always seems to be better than cleaning with a cloth and a spray-on type cleaner. What other steam companies and I would agree on is that steam is an excellent way to clean. It’s such a difficult question to answer as there are so many variables to consider in killing or removing contaminants from a surface with steam. We wished we had a definitive answer to that question.
