It is important to prepare your hemp for the first use. Best is about 20 minutes boil followed by gentle detergent wash, else simply do a hot soak followed by gentle detergent wash. As a natural fibre, it is normal for hemp to shrink by up to 8-12% of its size as well as change shape.

Every once in a while you can boil your washed inserts (not the covers) for 10 minutes to help rid of detergent remains or unpleasant odors.
