High-touch surfaces like doorknobs, switches, and countertops are touched dozens of times a day. If they aren’t disinfected properly, they can quickly spread germs and illnesses. That’s why it’s important to choose a household products company that uses safe and effective disinfection methods. But how can you tell if their process truly works? In this blog, we’ll walk you through simple ways to evaluate their methods so you can feel confident in your choice.
Understanding Key Terminology
Disinfection vs Sanitization vs Cleaning
These three terms are often used together, but they aren’t the same. Cleaning removes dirt, dust, and debris from surfaces but doesn’t necessarily kill germs. Sanitization reduces the number of germs to a safe level, according to public health standards. Disinfection, on the other hand, goes a step further by killing most bacteria and viruses on a surface when products are used correctly. When evaluating a company’s methods, make sure they focus on disinfection for high-touch surfaces, not just basic cleaning or sanitizing.
High-touch surfaces , what qualifies?
High-touch surfaces are areas that people frequently touch throughout the day. Common examples include doorknobs, light switches, faucet handles, phones, keyboards, countertops, elevator buttons, and remote controls. Because these surfaces are used so often, they are more likely to spread germs quickly. A household products company should clearly identify high-touch areas and include them in their disinfection process. If they don’t focus on these surfaces, their method may not be effective.
Claims like hospital-grade, EPA-registered, virucidal, broad-spectrum
When companies promote their disinfection products, they often use terms that sound impressive—but it’s important to understand what they actually mean. Hospital-grade usually indicates the product meets standards for killing common healthcare-related pathogens. EPA-registered means the product has been tested and approved by the Environmental Protection Agency for effectiveness and safety. Virucidal means it can kill or deactivate viruses. Broad-spectrum suggests the product works against a wide range of microorganisms such as bacteria, fungi, and viruses. Knowing these terms helps you judge whether the company is using products that are truly effective for high-touch disinfection.
Criteria for Evaluating Disinfection Methods
Regulatory compliance and certifications
A reliable disinfection method must meet industry standards. Check whether the company uses products that comply with EPA regulations. EPA-approved disinfectants have been tested for effectiveness and safety when used properly. Also, look for third-party certifications such as Green Seal or eco-labels, which confirm that products meet certain environmental or safety standards. If a company cannot provide proof of compliance or certification, their methods may not be trustworthy.
Product formulation and efficacy
The effectiveness of a disinfection method depends on the product’s ingredients and how they work. Review the active ingredients and which pathogens they are designed to target—some products may only work against bacteria and not viruses. Check the recommended contact time, which is how long the product must stay on the surface to work, as well as dilution instructions if the product needs to be mixed before use. Also, make sure the disinfectant is safe for the surfaces being treated to avoid damage. Reliable companies often provide evidence of testing, such as lab results or independent studies, to prove their product’s performance.
Application methods and protocols
How the product is applied plays a big role in how well it works. Companies may use different methods like spraying, wiping, fogging/misting, or electrostatic application. The chosen method should be appropriate for high-touch surfaces and ensure full coverage. It’s also important to know how often these surfaces are disinfected—high-traffic areas may need more frequent treatment. A good company will follow a clear protocol or checklist and provide easy-to-understand instructions for consistent application.
Safety and environmental considerations
Disinfection should protect people without causing harm. Check whether workers follow safety measures, such as wearing proper PPE, ensuring ventilation, and receiving training on how to handle products. The disinfectant should also be safe for surfaces like fabrics, electronics, and sensitive materials. Consider the environmental impact as well—some products contain VOCs (volatile organic compounds) that can affect air quality, while others may be biodegradable and come in eco-friendly packaging. Companies that prioritize safety and sustainability demonstrate responsibility and reliability.
Monitoring, quality assurance & accountability
Effective disinfection goes beyond applying products—it also involves tracking results and maintaining standards. Ask whether the company uses monitoring tools, such as ATP testing, swab checks, or audit logs to verify cleanliness. A professional company will provide summary reports or updates to show what has been done and when. It’s also important to know how they handle mistakes—do they have a plan for re-cleaning missed areas or addressing failures in the process? Accountability ensures consistent quality and customer confidence.
Questions to Ask the Household Products Company
What pathogens has this product been tested against?
Not all disinfectants are effective against every type of germ. Ask the company which pathogens the product has been tested on, such as bacteria, viruses, or fungi. This helps you confirm whether it can handle common threats like influenza, COVID-19, or norovirus. A company that can provide clear test results or lab data is more credible.
What is the required contact time for the product on typical high-touch surfaces?
Disinfectants need time to work. The contact time is how long the surface must stay wet for the product to effectively kill germs. If the company can’t provide this information, their method may not be reliable. Make sure the contact time is practical for your environment and that staff follow it correctly.
Do you provide documentation or proof of application?
Proper documentation shows accountability. Ask if the company tracks each disinfection task using checklists, logs, or photo evidence. This helps ensure no surface is missed and allows you to verify that the process was completed as promised. Good documentation also helps with audits or compliance requirements.
How do you train your staff on proper disinfection protocols?
Even the best products won’t work if used incorrectly. Confirm that the company provides regular training for their team on proper application, dilution, contact time, and safety procedures. Well-trained staff are more likely to apply the disinfectant correctly and consistently.
How do you ensure compatibility with the various surfaces in my facility?
Some surfaces, such as electronics, polished wood, or fabrics, can be damaged by certain chemicals. Ask how the company checks for surface compatibility before applying disinfectants. A professional provider should evaluate your environment and recommend suitable products for each material.
How often do you revisit/disinfect high-touch surfaces, and how is that schedule determined?
High-touch surfaces may need repeated disinfection throughout the day. Ask how the company determines the frequency of applications—whether it’s based on traffic levels, industry standards, or risk factors. A structured schedule ensures consistent protection.
What safety precautions are in place for users, occupants and the environment?
Safety should be a top priority. Ask about the protective measures taken during application, such as PPE for workers, ventilation requirements, or temporary area restrictions. Also inquire about the product’s impact on the environment, including whether it contains harsh chemicals or has eco-friendly options. A responsible company will balance effectiveness with safety for people and the planet.
Red Flags to Watch Out For
Vague claims without evidence
Statements like “kills 99.9% of germs” may sound reassuring, but without lab results or third-party testing, there’s no proof of effectiveness. If the company cannot provide documentation or listing on trusted regulatory platforms like the EPA, this is a major red flag. Always ask for supporting data.
No clear contact time or dilution instructions
A disinfectant must stay on the surface for a specific time to work. If the company doesn’t specify how long the product should remain wet, or if they offer no guidance on dilution for concentrated solutions, their process may be ineffective or even unsafe. Incorrect use can lead to poor results and wasted product.
Use of generic language: “all surfaces” without specifying material limitations
Not all disinfectants are safe for every type of surface. If a company vaguely states their product works on “all surfaces” without addressing factors like wood, metal, plastic, or electronics, they may not be prioritizing surface safety. A lack of surface compatibility knowledge can lead to damage or ineffective disinfection.
Lack of worker training or documented protocol
Disinfection requires proper technique, especially for high-touch areas. If staff are not trained or the company cannot explain their disinfection steps, it could mean inconsistent coverage. A professional company should have documented procedures and provide clear training for their team.
No quality control measures or follow-up reporting
A reliable provider should have systems to verify results, such as ATP testing, surface swab checks, or internal audits. If the company cannot show proof of monitoring, tracking, or reporting, it may indicate a lack of accountability. Consistent reporting boosts transparency and client trust.
How to Integrate This Evaluation into Your Facility’s Program
Aligning with your facility’s risk profile
Every facility has different disinfection needs. A healthcare setting requires more frequent and targeted disinfection compared to a standard office, where the risk of pathogen spread may be lower. Industrial environments may involve unique surfaces and heavier traffic levels. By understanding your facility’s risk profile, you can select products and methods that match your sanitation needs without overusing or underusing disinfectants.
Scheduling: daily, weekly, event-based disinfection
Once risk is determined, set a clear schedule for treating high-touch surfaces. In areas with heavy traffic, such as lobbies or shared spaces, daily or even multiple disinfections may be necessary. Low-traffic areas may follow a weekly schedule. Event-based disinfection—such as after meetings, shift changes, or outbreaks—ensures that cleaning aligns with real-time usage. A structured schedule helps maintain consistency and prevents gaps.
Documentation and audit trail: building your own checklist and log
Keeping records is critical for accountability and compliance. Create your own checklist that includes all high-touch areas, product details, contact time, and assigned personnel. Logs should track when and how each area was disinfected. This documentation allows you to monitor consistency, measure performance, and respond effectively to audits or inspections.
Communication with occupants: transparency on methods and use
Clear communication builds trust. Share key points about your disinfection process with building occupants or employees, such as the products used, frequency of disinfection, and how high-touch surfaces are monitored. Posting schedules or providing updates after major cleanings can help reassure users that their environment is being properly maintained.
Continuous improvement: reviewing results, updating products/methods
Disinfection programs should evolve over time. Regularly review cleaning logs, inspection outcomes, and occupant feedback to identify areas for improvement. If products lose effectiveness or new pathogens emerge, consider updating disinfectants or methods.
