Before you begin to clean, prepare yourself with the right equipment. Remove anything that can scratch surfaces or become entangled in sensors.

What to use:

• Soft microfiber cleaning cloths
• Mild non-abrasive soap or a neutral-pH cleaner
• A small soft-bristle brush (in small areas)
• A spray bottle of warm water
• Lint-free paper towels
• Disposable gloves

Don’t use:

• Strong chemicals like bleach, ammonia, or alcohol sprays on sensors themselves
• Steel wool, scouring sponges, or abrasive scrubbers
• High-pressure water jets sprayed at the sensor window

For larger facilities, it may not always be practical to shut off the water supply during cleaning. However, if you’re working on a single faucet or in a smaller restroom, temporarily turning off the water can prevent accidental activation and help ensure a more controlled cleaning process.

Some faucets have a cleaning modes option (off the sensors temporarily). Check the owner’s manual for this setting—this is convenient and stops water flow activation when cleaning.

Start at the faucet body. Spray your neutral cleaner onto a cloth and not onto the faucet, so fluid won’t seep into the sensor window or seams. Wipe the faucet with the cloth, cleaning away fingerprints, soap scum, and water spots.

For tough buildup, use your soft-bristle brush in small circular strokes on near-base areas and joint regions. Always damp-wipe with a microfiber cloth to prevent streaking.

The “eyes” of your touchless faucet are its sensor window. Any smudge, dust, or dirt there could lead to detection problems.

• Wipe the sensor gently with a slightly damp microfiber cloth.
• Never spray cleaner onto the sensor—overspray can enter the electronics and ruin them.
• For long-term heavy buildup, wet cloth very lightly with warm water and wipe very gently.

Consistency is key: daily cleaning of the sensor area prevents buildup from hardening and makes performance issues unlikely.

Mineral buildup will eventually clog a faucet aerator and reduce water pressure. Aerators on most commercial touchless faucets are simple to remove by unscrewing.

• Remove the aerator carefully.
• Soak in equal parts vinegar and warm water (50% each) for 15–30 minutes.
• Rinse well with warm water.
• Securely install the aerator.

This is especially important where there is hard water in a building because buildup occurs more quickly.

The majority of touchless faucets operate using replaceable batteries, although a few operate on AC power. In your maintenance routine:

• Check for corrosion or leakage in battery compartments.
• Replace batteries in twos, not singles, to ensure even power supply.
• Check connections are tightened in AC-driven ones.

A well-powered faucet will neither give false positives nor fail during use.

After you have sanitized it, restore water supply (if shut off) and check the faucet. Position your hand underneath the sensor to verify proper activation. Make sure there is balanced water pressure and the faucet shuts off automatically as soon as you vacate.

Testing is the way by which you will ensure that water or soil has not seeped through to influence sensor function and enable prompt correction of issues.

To gain optimum performance from your touchless faucets and minimize emergency calls, implement these best practices:

• Develop a Cleaning Schedule: Clean out the sensor and faucet housing every day to avoid clogging. Scale the aerator monthly or every quarter based on water hardness.
• Train Your Janitorial Staff: Your janitorial staff may be ignorant of sensor technology. Incorporate training for correct cleaning procedure.
• Maintenance Records: Keep track of battery replacement, descaling, and inspection. This will allow repeated issues to be caught and preventative maintenance to be easy.
• Check Out Manufacturer Directions: Different manufacturers offer different recommendations. Always check the user manual for cleaning compatibility.

• Direct spritz of cleaners on sensors – This destroys internal electronics.
• Abrasive material – Scratch not only ruins the finish but also degrades sensor accuracy.
• Ignores minor issues – Low water pressure or slow sensor can be indicative of buildup or battery issues. Correct these prior to system failure.

Touchless faucets do not have to be a pain to keep around. By executing a routine cleaning routine, facility managers and custodial staff can have clean bathrooms, increased fixture longevity, and avoid costly repairs.

Keep in mind: the key is light, routine care—coordination with the faucet as a sanitary piece of equipment and a sensitive unit of technology. Under periodic maintenance, touchless faucets deliver years of quiet, sensor-activated convenience.
