# HOW TO CLEAN, DISINFECT, SANITIZE WITH THE PRESSURE WASHER

[![HOW TO CLEAN, DISINFECT, SANITIZE WITH THE PRESSURE WASHER](https://blog.comet-spa.com/hubfs/Sanificazione/A_sanificazione_2.jpg)](https://blog.comet-spa.com/cleaning-en/how-to-clean-disinfect-sanitize-with-the-pressure-washer)

With the [Covid-19](https://www.who.int/emergencies/diseases/novel-coronavirus-2019/events-as-they-happen) emergency, we have all become much more careful about **cleaning, disinfection and sanitization.**

But do we really know the meaning of these terms, and what’s the difference between disinfect and sanitize? Here are some answers and some tips on how a pressure washer can **speed up** the now indispensable **operations of disinfection and sanitization** both at home and at work**.**

## **Cleaning, disinfection and sanitization, that's the difference.**

### **Cleaning**

Cleaning basically means **removing dust, dirt** and foreign bodies from a surface, object or environment.   
The chemicals that help to remove dirt are cleaning agents**.**

### **Disinfection**

Disinfection is an operation designed to **destroy pathogenic microorganisms.** The elimination of germs and bacteria can be obtained through **biocides**, chemical agents authorized by the Ministry of Health that contain disinfectant active ingredients (such as chlorine, alcohol, ammonia, hydrogen peroxide, etc.), or **through physical agents such as heat,** or its opposite, low temperatures (think of the food blast chiller).

**Sterilization**, on the other hand, is the elimination of all microorganisms, both pathogenic and non-pathogenic.

### **Sanitization**

Sanitization is a more complex process that must **guarantee the healthiness of an environment.**  
The environment must, therefore, be **healthy and disinfected**, but not necessarily clean.

### **Hygienisation**

Hygienisation is linked to the concept of **disinfection and cleaning** limited to an object or part of the whole.   
For example, if we refer to a structure with more than one room, we can say that we have to carry out **hygienisation** of a specific **room,** not of a large environment such as a shed, but a closet, a machine, a room, etc..

## **Sanitize with a home pressure washer**

Is it possible to **sanitize an** outdoor **environment** with a pressure washer rather than relying on expensive specific machinery or the service of a professional?  
**The answer is yes**, but with the appropriate precautions.

Given the great versatility of a pressure washer, it is also possible to use it to sanitize by **mixing sanitizers with pressurized water.**  
However, it is advisable to bear in mind that most sanitizers are based on chlorine, an element that is particularly aggressive with the materials of which the pump of a common pressure washer is made.  
Therefore, even if you have a cold water pressure washer with a built-in detergent tank, we strongly recommend that you keep it empty and **use a** [**foam lance** in](https://www.comet-spa.com/products-category/foam-lances/) order to **mix the sanitizer only after the water has been pressurized** while preventing the additive liquid from passing through the pump.

![A_sanificazione_3](https://blog.comet-spa.com/hs-fs/hubfs/Sanificazione/A_sanificazione_3.jpg?width=3809&name=A_sanificazione_3.jpg)

The entire range of[Comet cold water pressure](https://www.comet-spa.com/products-category/krm/) washers allows the use of this type of lance, even those with built-in detergent tank.   
For some models, such as e.g. the[KL 1680 Gold Plus](https://www.comet-spa.com/products-category/kl-1680-gold/), the **foam lance** is included in the standard accessory kit.   
These lances are equipped with a container for dispensing detergents or sanitizers. The disinfectant is mixed with the already pressurized water by means of the ["Venturi" system](https://it.wikipedia.org/wiki/Effetto_Venturi) and generates a dense and effective foam.   
The foam lance can be purchased separately and applied to any Comet pressure washer.

To **disinfect surfaces and objects** that we use in the yard or on the terrace just fill the tank with a **disinfectant detergent**, high pressure will do the rest and our outdoor areas will be cleaned and sanitized in a very short time and with very little effort.

## **Sanitize with a hot water pressure washer**

If you need to sanitize large environments such as laboratories or commercial activities, here are the tools for this purpose (we recommend you to refer to our dedicated products such as [sprayers](https://www.comet-spa.com/products-category/sprayers/), [trolleys and wheelbarrows](https://www.comet-spa.com/products-category/trolley-and-wheelbarrows/), combustion or battery and our [steam generators](https://www.comet-spa.com/products_category/professional-series-dry-steam-generators/)).

If you need to sanitize large external surfaces, **hot water pressure washers** are definitely the best solution, because they combine **high temperatures** with the power of chemical sanitizers through the use of foam lances.

The[Comet](https://www.comet-spa.com/cleaning/red-series-water-cleaners/) [Red](https://www.comet-spa.com/it/cleaning/idropulitrici-red-series/)[Series](https://www.comet-spa.com/it/cleaning/idropulitrici-red-series/) offers **professional and semi-professional** models for any **flow rate, pressure and temperature** requirements**.**

The jets of these pressure washers can reach even **110 degrees** with 210 bar pressure for a **really deep sanitization** of any surface and the removal of greasy dirt and grease, which is excellent for **mechanical** **workshops, food and wine industries**.  

![A_sanificazione_1](https://blog.comet-spa.com/hs-fs/hubfs/Sanificazione/A_sanificazione_1.jpg?width=3840&name=A_sanificazione_1.jpg)

## **Sanitize with steam**

Some of our pressure washers, both electric ([KM](https://www.comet-spa.com/it/products-category/km-extra/)[Extra](https://www.comet-spa.com/products-category/kf-extra/), [KF Extra](https://www.comet-spa.com/products-category/kf-extra/)) and petrol ([FDX Hot Cube](https://www.comet-spa.com/products-category/fdx-hot-cube/)) offer the opportunity to **thoroughly sanitize** an environment in a completely **ecological and professional** way, thanks to the sanitizing power of steam. The 140° steam jet emitted by the machine is able to **kill 99% of germs, bacteria and** viruses without the use of chemical additives.

These pressure washers are the **top of the range** in terms of **cleaning and sanitizing** and are designed for companies and **professionals in the sector.**

## **Sanitize places without electricity**

If we often have to sanitize in a professional way and **the places to be treated are located far from a power outlet,** think of public parks with children's playgrounds and benches, bus shelters, factory yards, monuments, all the places that are frequented outdoors by many people, how to effectively sanitize everything?

To **sanitize in a professional way** it is necessary to use **hot water or steam pressure washers**, and there are models with [**endothermic**](https://www.comet-spa.com/cleaning/high-pressure-washer/#endothermicengine) or “combustion”[**engine**](https://www.comet-spa.com/cleaning/high-pressure-washer/#endothermicengine).

They are completely autonomous and easily transportable machines and can be **powered by petrol or diesel.** One example is the Comet [X SERIES](https://www.comet-spa.com/cleaning/x-series-water-cleaners/) with different models and a wide range of performance.

## **Versatility of both home and professional pressure washers**

A pressure washer, both home and professional, is always an excellent investment because it is a **very versatile machine** with which you can meet different needs both at home and work.

The applications of pressure washers are many and even in the [**Coronavirus**](https://www.who.int/emergencies/diseases/novel-coronavirus-2019/events-as-they-happen)**emergency** we have seen how those who already had one were able to **use it immediately to sanitize** outdoor environments both at work and home.
