Commercial Sanitizing & Disinfecting Solutions

Yes, they will. With only a one-minute contact time, GERMGUARD TK-128 has been proven to kill coronaviruses including the virus that may cause COVID-19.

At Guardian Chemicals, we offer several cleaners and disinfection chemicals for all types of environments and applications. Examples include: GERMGUARD, a multi-purpose cleaner and disinfectant; and ECOZYME, a highly concentrated enzymatic cleaner and deodorizer.

Yes, Guardian Chemicals has solutions for a wide range of purposes, including cleaners and degreasers, water treatment products, degassing agents, defoamers, descalers, fountain solutions and more.

Sanitizing reduces microbial load to a level considered safe, typically a three-log reduction on food-contact surfaces. Disinfecting kills a defined list of organisms to a higher standard. The label and the required contact time tell you which claim applies, and the same product at two dilutions can do either.

Most failures are procedure rather than product. The surface was not cleaned first and soil deactivated the active, the wet contact time was too short, the dilution was wrong, or hard water interfered with quaternary chemistry. Check wet contact time and in-use concentration before you change products.

The surface has to stay visibly wet for the full time stated on the label. Wiping dry after thirty seconds when the label calls for ten minutes means the product never made its claim. If the surface dries early, reapply rather than assume it worked.

In almost every case, yes. Grease, protein and biofilm physically shield organisms and chemically consume the active ingredient. A two-step clean then disinfect is the standard for food plants and healthcare, and skipping the first step is the most common reason a validated product fails a swab.

Any product making a disinfectant claim in Canada needs a DIN from Health Canada. We provide the registration number and the label claims for any product you are evaluating so you can verify it against your own audit requirements before it comes on site.

Cotton and some microfibre absorb quaternary ammonium out of solution, so the cloth holds more active than the surface receives. Use compatible wipe material, change solution on a set interval, and test the concentration at the point of use rather than trusting the dilution ratio.

Test strips or a titration kit at the point of use. Dispensers drift, venturi injectors wear, and a dilution station that was correct at commissioning is often out of range six months later. Verifying in use is the only way to know what the surface actually sees.

Yes. Calcium and magnesium tie up quaternary ammonium actives and reduce available concentration, and high alkalinity shifts the pH of acid sanitizers out of their effective range. We often know the water quality for a region already, so the fix is usually a formulation change rather than a water treatment project.

Both. Our field team sets up dilution control, written procedures, training and verification alongside the chemistry. A sanitation programme that fails an audit usually fails on documentation and verification, not on the product in the drum.

GERMGUARD, GERMGUARD TK-128 and GERMGUARD TK-128 RTU cover different concentrations and application methods, from dilution-station use through to ready-to-use spray. The right one depends on your surfaces, your required contact time and whether staff are diluting on site.
