Clean the wood surface you want to vanish using mild wood cleaning solutions, such as a 75-25 mixture of liquid laundry detergent that is mild enough for woodwork made of teak wood. Scrub the wood lightly in the direction of the grain using the wool pad. Avoid using abrasives such as steel wool because they leave scratch marks on wood. Alternatively, clean the wood using a mixture of a cup of mineral spirits and two tablespoons of linseed oil.
Apply the first coat of varnish on the wood using a brush. Dilute the first coat of varnish by 50 percent using thinner as per the instructions on the varnish's container label to ensure it penetrates into the wood. Place the object under the halogen light to get the actual color; different vanish colors appear differently under various lights.
Apply two to three coats to polish the finished piece. It is advisable to apply four to five coats on new bare wood that has not been varnished or treated before.
Determine the regions you want to have another color and establish whether it is lighter or darker than the shade of your varnish. This is because one color varnish brings out different colors depending on the application procedure you choose to use; the more the coats the darker the color.
