Cleaning & Maintenance
Take it down. Wash it. Hang it back up.
Unlike metal duct, Prihoda fabric ducting and diffusers come down in sections and go straight into a washing machine. No specialist duct-cleaning crews required.
Every system is made from high-performance synthetic fabrics with no natural fiber additives, so it holds its shape and performance wash after wash.
Three quick checks
Before any section goes in the machine, run through these three checks.
Read the care label
Every section has a washing label sewn in. Follow it exactly. It overrides any general guidance.
Remove hardware
Take out any hoops, arcs or tensioning systems before the fabric goes in the machine.
Confirm your fabric
Your material is listed in your order’s technical description. Some fabrics are not machine washable.
Six steps to a clean system
From dusty duct to clean, reinstalled system — here is the full routine.
Vacuum first
Very dusty sections? Pre-clean with a vacuum, compressed air or a soft brush.
Machine wash
Use an industrial detergent at 40°C (104°F). Spin at 400 rpm and rinse thoroughly. Repeat the cycle for heavy soiling.
Hand-clean the rest
Non-washable fabrics (Plastic, Foil, Glass, Translucent): vacuum, wipe with a damp cloth or rinse with water.
Disinfect if required
Add a disinfectant to the wash where your site demands it. Only use one that is compatible with the care label.
Dry and reinstall
Dry sections well before reinstalling. Tip: the system’s own airflow can finish the drying.
Spot-clean in place
Light surface dust can be vacuumed off without taking the system down.

Clean on your schedule, not your duct's
Cleaning frequency depends on your environment and local hygiene standards. A food plant or cleanroom will wash more often than an office or warehouse. Our team can recommend a cleaning routine and compatible disinfectants for your site.
“Fabric ducting and diffusers can be thoroughly cleaned by washing. You can see that every day in our own laundry room.”

Cleaning questions, answered
Can fabric ductwork be washed?
Yes. Most Prihoda fabrics go straight into a washing machine at 40°C (104°F) with an industrial detergent. Plastic, Foil, Glass and Translucent fabrics are cleaned by vacuum, cloth or water rinse instead.
Do I need to remove the system to clean it?
For a full wash, yes. Sections detach and reinstall quickly. Light surface dust can be vacuumed off with the system in place.
Can I disinfect fabric ducts?
Yes. Add a disinfectant to the wash if your facility requires it, as long as it’s compatible with the care label (no bleach).
How do I dry fabric ducting after washing?
Air-dry only, never tumble dry. Dry sections well. Once reinstalled, the system’s airflow can help finish drying.
How often should fabric ducts be cleaned?
It depends on your environment and local hygiene standards. Contact us and we’ll recommend a schedule for your application.
