Storage:

• Store rolled in a clean, dry environment away from direct sunlight and prolonged UV exposure, which can degrade polyester fibers over time
• Keep away from excessive heat sources; polyester is sensitive to high temperatures and can deform or melt if stored near heating equipment
• Avoid storing in areas with heavy airborne dust or oils — while the IFR properties will not wash out, particulate accumulation can still diminish practical flame resistance performance
• Use breathable fabric or muslin storage covers; avoid sealed plastic wrapping that can trap heat and moisture

Folding:

• Rolling onto a rigid tube is strongly preferred over folding for any storage period exceeding a few days
• If temporary folding is required for transport, use broad, loose folds with minimal crease pressure to prevent permanent set lines in the polyester weave
• Do not place heavy items on top of folded fabric, as polyester can take on permanent creases under sustained pressure

Periodic Cleaning:

• Spot clean with a lightly dampened cloth; polyester is more moisture-tolerant than cotton muslin, but avoid excessive saturation
• Vacuum gently using a soft brush attachment to remove surface dust and particulate buildup
• Unlike chemically treated FR cotton muslin, water-based cleaning will not remove the IFR properties of this fabric — however, keep cleaning minimal to maintain surface quality for projection use
• Compressed air is acceptable for light dust removal between uses

Major Cleaning:

• Standard laundering (machine wash, gentle cycle, cool water) is permissible without risk of losing flame resistance — the IFR treatment is inherent to the fiber and will not wash out
• Use mild, non-residue detergent; avoid fabric softeners or bleach, which can affect polyester surface texture and projection performance
• Tumble dry on low heat or hang dry — do not expose to high heat, which can cause polyester deformation
• After any major cleaning, conduct an NFPA 705 field test before returning the fabric to service, particularly if the fabric has been in storage or heavy use

Safety & Handling:

• Although polyester is inherently more resilient than cotton, avoid dragging the fabric across rough or abrasive surfaces that could snag or pill the weave and affect the projection surface quality
• For large drops and full-width (128″) installations, use multiple personnel and appropriate rigging equipment to prevent uneven tension, tearing at attachment points, or batten pocket failure
• Inspect all seams, grommets, and batten pockets before each hang; do not use fabric with compromised structural attachment points
• When used as a projection surface, ensure even tensioning across the full width — any wrinkling or slack will distort the projected image

Flame Resistance Maintenance:

• The IFR flame resistance is permanent for the life of the fabric — it is woven into the polyester fiber itself and does not rely on chemical surface treatments
• Flame resistance will not wash out under any standard cleaning conditions
• Despite the inherent permanence of IFR, annual field testing is still recommended using the NFPA 705 Field Test Method for Textiles, as accumulations of airborne dust and oils may diminish practical flame resistance over time
