Are your hands washed? Why proper handwashing makes sense—and how UV handwashing checks offer a solution for hygiene training.
Since we constantly use our hands as tools in our daily lives, they pick up pretty much everything lurking on surfaces. Is handwashing essentially the simplest, most affordable, and most effective form of "insurance" against illness imaginable? Many individuals, institutions, and companies have varying ideas and requirements regarding hygiene—whether driven by a sense of social responsibility, guidelines, regulations, or laws. There are many reasons for maintaining good hand hygiene; here are a few examples:1. Hand hygiene to protect against infectious diseases
The most obvious reason: we remove pathogens. Whether bacteria, viruses, or fungi—many germs are transmitted through direct contact.
- Gastrointestinal infections: Pathogens like noroviruses are often spread via contact transmission.
- Respiratory diseases: Flu or cold viruses end up on our hands when we sneeze or touch doorknobs.
2. Neutralizing the “face trap”
Studies show that we unconsciously touch our faces about 16 times an hour. In doing so, we transport germs directly to our body's entry points. The mucous membranes of the mouth, nose, and eyes act as a superhighway for pathogens to enter our system. Clean hands break this chain.
3. Protection for others (community protection)
Washing your hands is an act of courtesy and responsibility. When you wash your hands, you protect not only yourself but also:
- people with weakened immune systems.
- elderly people or children around you.
- colleagues (nobody likes the office “superspreader”).
4. Food safety
Washing your hands is essential before you prepare, cook, or eat food. It prevents germs from your hands (picked up from contact with people, doorknobs, money, or animals) from getting into your food and, consequently, directly into your digestive tract.
Testing proper handwashing with CONTROLETTI UV hygiene check lotion – Instructions.
Even application
Dispense an amount appropriate for your hand size (roughly the size of a hazelnut) into your hand and spread it evenly over your hands, just like hand cream. Perform an initial check using the Controletti UV lamp. Areas that are well-covered will glow a bright blue-purple under our specially designed CONTROLETTI UVA lamp; areas with insufficient coverage will be clearly visible and can be touched up as needed.Washing and Checking
The next step is thorough hand washing (for at least 20–30 seconds) using water and soap or washing lotion. This involves washing not only the palms but also the areas between the fingers, the fingertips, and the backs of the hands.We are happy to provide a "step-by-step guide" to thorough hand washing, as well as various training concepts for an engaging hygiene training session.
The subsequent second check under the CONTROLETTI UVA blacklight lamp reveals any deficiencies—indicated by visible fluorescent residues—which should then be addressed during the evaluation.

Practical training
The hands-on hand-washing test using the Controletti UV system shows immediately and unmistakably where hand hygiene needs improvement. Passing the test contaminant around the group was also a success. It is a test that should really be mandatory for medical personnel.
A valuable learning experience for the entire team.
Highly recommended!"

Training with real "aha" moments!
Instead of dry theory, the focus was on hands-on practice. You generally assume you are washing your hands thoroughly—but the blacklight immediately and starkly reveals the weak spots (such as the areas between fingers or around nail beds). It is both shocking and fascinating to see what shows up under the UV lamp and which spots get missed during routine handwashing. A great method that really sticks with you. Many thanks!”
Simulating the transfer of dirt or germs such as bacteria, viruses, or mold.
The CONTROLETTI UV Hygiene Checklotion blacklight test allows you to simulate how microorganisms (bacteria, viruses, or fungi) are transmitted.Simply put, germs "travel" from a place where they naturally occur (e.g., raw meat) to a place where they can pose a risk (e.g., ready-to-eat salad), or they are passed on to other people or objects via handshakes.
A handshake serves as a practical test scenario: the "transmitter" rubs CONTROLETTI UV Hygiene Checklotion onto their fingers or entire hand and then shakes hands with one or two other people.
This specially developed training lotion—which fluoresces under UV light and washes off easily—can also be used to test the transmission pathways of dirt and germs (bacteria, viruses, mold, etc.) by applying CONTROLETTI UV Hygiene Checklotion to items such as door handles, pens, mobile phones, or keys, and subsequently checking how the substance spreads.
Simulating Biofilms – Detection, Removal, and Prevention
Biofilms are complex communities of microorganisms that rapidly colonize surfaces in aqueous or moist environments. Common bacteria as well as hazardous pathogens—such as *Pseudomonas*, staphylococci, and streptococci—can be present and cause infections.Whether in the food industry or in healthcare settings, detecting biofilms on surfaces—such as kitchen sinks, water bottles, coffee machines, or production equipment used for quality assurance—is crucial for hygiene.
Checking for Gaps in Skin Protection and Care Using UV Light
Controletti UV Hygiene Check Lotion offers a solution for verifying the complete, gap-free application of skin protection products—such as sunscreen, lotions, or general skincare creams—since applying too much or too little product can make a crucial difference. Our Controletti UV check system allows you to verify the application of skin protection products (whether used before or during work, or for post-work skincare) and make the coverage visible using a CONTROLETTI blacklight lamp.
In professional settings—such as healthcare, skilled trades, or industry—unprotected areas of skin exposed to moisture or chemicals can quickly lead to painful occupational dermatoses and allergic reactions. In private life, too—particularly regarding sun protection—dangerous gaps often go unnoticed on the ears, neck, or tops of the feet, drastically increasing the risk of skin damage.
This is where our system’s direct visual feedback comes into play: under the special light of the blacklight lamp, areas of skin with optimal coverage glow brightly. Dark spots immediately and unmistakably reveal any gaps in application. Consequently, this method is not only suitable for quick self-checks but also serves as an excellent, interactive training tool for workplace safety seminars and educational campaigns in schools or other institutions. It fosters lasting habits regarding the correct and comprehensive application of protective products, raises awareness of personal skin health, and effectively prevents long-term skin damage.

Protective Clothing – Disposable Glove Usage Test with UV Light
The primary goal when handling medical gloves is the consistent prevention of cross-contamination. When putting them on, the main objective is to avoid contaminating the gloves with germs from one's own hands before use. When taking them off, the glove is considered contaminated after the task is complete; the correct technique ensures that pathogens are not transferred to the wearer's skin during removal.
Using a "CONTROLETTI UV Lamp" and "CONTROLETTI UV Hygiene Check Lotion," the process of using disposable protective gloves can be tested to ensure no hand contamination occurs. CONTROLETTI thus serves as a vital hygiene tool for protecting both patients and wearers from infection, as well as providing protection against biological, chemical, and physical risks and substances.
The practical execution of such a test is as simple as it is impressive, making it ideal for regular training purposes. To realistically simulate the risks involved in glove removal, for instance, a fluorescent UV lotion is applied to the outside of the gloves being worn—representing potentially infectious blood, secretions, or hazardous chemicals.
The test subject then proceeds to remove the disposable gloves using their standard routine. The moment of truth follows immediately: under the black light of a UV lamp, it becomes instantly apparent whether the technique was flawless. Glowing spots on hands, wrists, or work clothing reveal even fleeting contact between unprotected skin and the contaminated outer surface of the gloves—contact that would have gone unnoticed by the naked eye.
This direct visual feedback creates a powerful "aha moment" for medical and nursing staff. Unlike purely theoretical instruction, the image of glowing contamination leaves a lasting impression.
Such practical tests significantly raise user awareness, help embed safe motor routines for glove changes, and underscore the absolute necessity of mandatory hand disinfection immediately after removing protective gear.
