On horizontal surfaces, remove greasy stains by soaking the wood where the stains are situated with Wood Floor & -Tile Cleaner/Grease Remover LOUIS XIII, then by sprinkling Terre de Sommières AVEL on the stains. The cleaner will deeply dissolve the greases and the Terre de Sommières will absorb it.
On the vertical part of panellings, applying Terre de Sommières AVEL is a delicate operation. We recommend to warm up the stains with a hair-dryer to dilute and afterwards remove the maximum with an absorbant paper.
For blood, rust, old ink, drink stains etc... use Bleach Stain Remover LOUIS XIII.
