Reusable cleanroom garments are washed and steam sterilised after every use. Each cycle stresses the fabric, seams and fittings a little. Sooner or later the garment stops doing its job, and it needs to be retired before that happens, not after.
The short answer
Reusable garments in continuous filament polyester are commonly rated for 50 to 100 or more cycles, but the real figure depends on the fabric, the construction and your process. We give cycle guidance for each garment with your quote, and you confirm it in your own validation. Where a garment falls in that range depends on the factors below.
What shortens garment life
- Sterilisation temperature and time. Steam sterilisation is commonly run at 121°C for 15 to 30 minutes or at 134°C for a shorter time. Higher temperatures and longer exposures age polyester and elastic faster.
- Laundering chemistry. High temperatures, strong alkaline detergents and bleach damage fibres and the conductive grid. Follow the care instructions.
- Drying. Over-drying at high temperature stiffens fabric and weakens elastic.
- Fittings. Zips, snaps and elastic usually wear out before the fabric does.
- Handling. Snagging on equipment and rough folding cause small tears that grow.
How to track garment life
- Give each garment an identity: a batch code, serial label, barcode or RFID tag.
- Log a cycle count every time it goes through laundry and sterilisation.
- Retire the garment at the cycle limit you have validated, even if it looks fine.
What to inspect before each use
- Holes, tears or thin patches when held up to the light
- Open or fraying seams
- Zips that do not close fully, missing or loose snaps
- Cuffs and ankles that no longer grip
- Faded or damaged conductive grid on antistatic fabrics
Why validation matters
Garment life claims are a starting point. Your laundry, your autoclave and your handling are unique, so plants typically test garments at intervals across their life (for example particle shedding, filtration and, for antistatic garments, electrical properties) and set their own retirement limit from that data.

Frequently asked questions
Can cleanroom garments be autoclaved at 134°C?
Many polyester cleanroom garments tolerate 134°C cycles, but higher temperatures age fabric and elastic faster. Use the cycle you have validated and check the garment's care instructions.
How do I know when to retire a cleanroom garment?
Count cycles per garment and retire at your validated limit. Retire earlier if inspection finds holes, open seams, failed zips or loose cuffs.
