Periodic maintenance for Cork wallcoverings should include light dusting or use of a vacuum cleaner with a soft brush attachment. If necessary, a slightly damp cloth may be used to remove a stain, being sure not to soak the material. More stubborn stains can be removed using clear, warm water and a non-abrasive detergent or household cleaner. Test first in an inconspicuous area. Do not use solvent-based cleaning agents, lacquer thinners, nail polish remover, pine oil, or cleaning agents containing bleach, which may cause discoloration over time
