Depending on the type of wood and type of finish, there are simple things you could do that will refresh the look of your furniture.
Stained or dull furniture
If your furniture has too many glass rim stains, or is looking dull, here's a simple trick- beeswax. Make sure you use one that has no stain or colour so it doesn't alter the look of your furniture. Simply apply some and rub it along the grain.
Teak wood lost its golden glow?
Teak that is exposed to the elements will turn grey and lose its golden glow. The teak itself is still good, it's just bleached. Linseed oil is a good way to bring back the glow. Be prepared to do a fair amount of rubbing as this is what burnishes the wood.
If you just want a new look to your furniture, try a bright colour like a purple or yellow. Keep in mind that while any oil based paint will do the trick, it wouldn't be easy to strip the paint off if you decide you don't like it. Paint adds a good layer of protection, so if you want to place your teak wood outdoors, the paint will add a more protection than wax or oil.
We don't recommend placing Sheesham or mango (local hardwood) outdoors. It's simply not strong enough to withstand the elements and will crack, even if it has oil paint on it.
Protecting your carvings
Carving are best protected with wax or oil. Make sure to use a soft brush to get all the details.
How the pros melt wax
Here's a trick I've seen our polish guys use for wax that's solidified- they light a match and throw it in the tin that has the wax. Then they shut the lid tight. The match melts a small portion of the wax, and extinguishes when the oxygen in the jar is used up. Don't try it at home though!
