How to clean a Raw Linen Bag: While the raw linen has a porous nature, tough stains such as ketchup just require a little bit of scrubbing to remove. The biggest advantage of the new products is that they can be completely immersed in water, making them machine washable and dishwasher safe. You can then simply lay them out to dry overnight. Putting them into a hot dryer is NOT recommended as it may shrink or melt certain materials in the bag.
