Washing & Care Suggestions
The care of peat products should be done exclusively by a professional (hand) wash at 30 °/ 86° Fahrenheit with the help of acidic detergents (about pH 6) without fragrances. Mild, sour detergent suitable for wool prevents too much humic matter from being washed out. Important is thorough rinsing and, with high water hardness, an addition of some vinegar in the last rinse water. Peat beds have a fungicidal action, preventing the growth of mold fungi.
Suggested is also not to put it in a dryer after washing, but lay it out on the floor on top of towels at room temperature.
Suggested is also not to wash it too often as the Comforter requires a Duvet-Cover and the Mattress Topper Cover-sheets through which the washing of those would suffice.
Daily ventilation like hanging it out to air is also essential here. Thus, the bedding can release the moisture absorbed during the night and thereby retain its function.
Overall the extent of applicability of these suggestions will depend on what people themselves actually do as far as taking care of their bedding and of their bedroom.
