Do not machine-wash or soak an OFUTON KOBO HIMARI or SORA shikibuton: clean a small surface stain locally and dry the area completely before using it again. Washability differs between shikibuton products, so these instructions apply to these two models, not to every shikibuton on the market.
Step by step
- Act promptly. Blot any liquid with a dry towel; do not rub, which spreads the mark.
- Dab with a cloth dampened with lukewarm water and a small amount of mild, neutral detergent, working from the edge of the mark toward the centre.
- Dab again with a cloth dampened with clean water to remove the detergent.
- Press with a dry towel, then air the shikibuton until the area is dry all the way through, not only on the surface.
Test any cleaner on a hidden spot first, and avoid bleach and strong solvents.
Why the whole shikibuton should not be washed
Washing leaves moisture deep inside the filling and support layer, which is hard to dry at home and can lead to odour or mildew. For heavy soiling, consult a cleaner experienced with futon bedding.
Preventing stains
A removable sheet or fitted cover, washed weekly, is the simplest protection for HIMARI 日葵 and SORA 宙. In homes with young children or pets, a protector adds a further layer; if it is waterproof and less breathable, air the shikibuton more often.
