Description Surface Preparation Remove debris and dirt from the surface. Tannin Spot Remover is ready to use. Do not thin. Before applying, test Osmo Tannin Spot Remover on substrate. (Trial application required!) Method of Application Spray Osmo Tannin Spot Remover evenly onto the spot until the surface is completely covered. Allow product to react for 30-45 minutes and wipe with a lint-free cloth. If necessary, repeat and then wipe clean with clear water. After drying, apply a suitable Maintenance Oil on the treated area, so that the wood is protected again. Note Protect metal (e.g. furniture hardware) and plants against direct contact (e.g. cover farm and ornamental plants with a tarpaulin or place out of reach). Depending on the stubbornness of the stain, some bleaching of the wood colour could be encountered. To reduce further bleaching, the surface should be re-finished with an appropriate Osmo oil. Carrying out small trials are highly recommended.
