Keep dry and in a suitable low humidity environment. For Stains: Apply gently with a wet clean cloth and then let the wind dry or the sun dry.
For mold: High humidity might lead to mold growth. Use a soft brush to carefully remove any obvious mold and clean it with a wet cloth. Then let the sun dry.
For storage: Wipe the rush-woven product with a clean cloth and let the sun dry. Place it in a plastic bag and seal it to protect it away from humidity and dust.
Caution: Don’t squeeze it or the rush grass might be broken. The rush grass is fragile right after sun exposure.
