There are two types of fabric construction used for blockout fabric and the two types require different cleaning methods.
Foam Coated Fabrics - the ones that have the white or grey coating on the reverse. We recommend you do not soak these curtains in water and best to spot clean and then Dry Clean. If you do decide to wash them yourself make sure you hand wash them with a mild detergent and do not use fabric softener. (this may result in the coating pulling away from the fabric). Gently wring the curtain and line dry them at once. Do not let the curtains sit. Make sure the coated surfaces do not touch each other as you line dry them.
Woven Triple Weave Fabrics - these are the ones that are very soft and drapey and have no coating on the reverse. These are made using high density yarn that is tightly woven. These you can gentle machine wash in a front loading machine. We suggest front loaders as the agitator in the centre of the machine can damage such large pieces of fabric by getting twisted around the centre agitator. It could also damage your machine.
Start by vacuuming the dirt off both the front and back of the curtain panels. This gets the dust out of the way before you get into the deep cleaning. The easiest way to vacuum your curtains is with a dust attachment while they’re still hanging.
Spot Clean with Laundry Soap
Remove the curtains from the hooks or rod. Then, place a small drop of soap on the problem spot, rub gently with a warm cloth, and then rinse with clean water. We recommend testing this in an inconspicuous spot on the curtain first to determine that your laundry soap will not alter the colour of the fabric.
Deep Clean with Soapy Water (for coated curtains)
Fill the bath with warm soapy water. We recommend using the instructed amount of soap for a small load of laundry. Blockout Curtains must be hand washed because the machines can easily ruin the layers. Gently squeeze and scrub the curtain fabric with your hands. Once the entire curtain has been washed, drain the bath and rinse the curtains with clean water.
Dry the Curtains
Ring the curtains to remove excess water. Line dry the curtains making sure the coated surfaces do not touch. Hang the curtains back on the rod or hooks to dry completely. Keep different curtain panels separated for faster drying.
