Excess oil must be removed 30 minutes after application. Step 3: Buff with a clean cloth until you achieve an even appearance. The oil only hardens after 12 hours. Do not cover any of the surface until the oil has hardened. IMPORTANT: Cloths with oil must be thrown in an airtight bag with a little water, as they can be highly flammable.
