To remove a grease stain from wooden furniture, warm it up with a hair-dryer to dilute it, which will enable you to eliminate the maximum with absorbant paper.
For the residue, we recommend to impregnate the wood where the stain is situated with Wood Floor &Tile Cleaner/Grease Remover LOUIS XIII, then sprinkle Terre de Sommièrs AVEL on the stain. The cleaner dissolves the greases in-depth and the Terre de Sommières absorbs them.
For blood, rust, old ink, drinks stains etc.... use the Bleach Stain Remover LOUIS XIII.
