Recommendation:
In general, we recommend that you do not wash the WAVESAFE® fabric too often in order to protect the fine silver threads from abrasion (such as knitwear, t-shirts, canopies, etc.). Airing it out frequently will help.
Washing:
Machine wash with the gentlest wash cycle 30° with like colors. Use mild, ecological detergent without softener, bleach and enzymes (use liquid detergent if possible). Do not put in the tumble dryer. Store the WAVESAFE® garment carefully without creasing.
Special tip for underwear, duvet- and mattress covers::
To extend the life of the garment even more, you can wear normal underwear underneath. Quilt and mattress covers: Use a normal duvet cover and bedsheet covering the shielding quilt and mattress covers.
