High tenacity polyester fabric is known for its durability and strength. To keep it clean and in good condition, you can follow these steps:

Remove any loose dirt or debris from the fabric by shaking it out or using a soft-bristled brush to gently sweep it off.

Spot clean any stains or spills as soon as possible using a mild detergent and a soft cloth or sponge. Dab the stain gently, and avoid rubbing it as this could damage the fabric. Rinse the area thoroughly with clean water.

For a deeper clean, fill a sink or bathtub with cool or lukewarm water and add a small amount of mild detergent. Place the fabric in the water and agitate it gently with your hands. Avoid twisting or wringing the fabric, as this could damage the fibers.

Rinse the fabric thoroughly with clean water, until all soap suds are gone.

If necessary, repeat the process with fresh water and detergent until the fabric is clean.

Once the fabric is clean, gently squeeze out the excess water or wrap it in a clean towel to absorb the moisture. Avoid wringing or twisting the fabric, as this could damage the fibers.

Hang the fabric up to air dry, making sure it is not exposed to direct sunlight or heat sources, which could cause shrinkage or damage to the fabric.

Iron the fabric on a low heat setting, if necessary, using a pressing cloth to protect the fabric from direct heat.
