First you should try with sponge cloth with warm water. If this tactis not serves the purpose than use thiner, petrlium jelly,hand lotion,windex,diswashing detergent and white vinegar etc.
Thanks for your
reply, I can able to remove the grease like residue left by stickers
using warm soapy water but after I removed the grease now that place is looking
like oil is spilled over. Now there is
no grease like leftover but the wood is look like oil is spilled. How can I able to remove or absorb the oil
from the wood?
