Wax or Dirt:
To clean wooden furniture of wax or dirt, dampen a clean rag with some mineral spirit and wipe across the wooden surface. Do this until all the dirt is picked up into the rag. To remove the dirt that collects in the grooves and crevices of carved areas use a cotton swab dipped in spirit.
For recent and mild stains, cover the stain with a clean, thick blotter and press down hard for a few minutes. If that doesn’t work, rub with salad oil, mayonnaise or white toothpaste and leave it on for about 15 minutes. For older or tougher stains leave it for more time, even overnight if required. Then wipe dry with a clean cloth.
Milk or Alcohol:
For milk or alcohol stains rub it with a paste of boiled linseed oil and rottenstone with the grain. Substitute pumice instead of rottenstone for dull finishes. Or rub with a cloth dampened with some ammonia. Wipe the surface dry and wax or polish.
Rub the stain with a clean cloth dipped in a mixture of cigarette ash with salad oil or lemon juice. Once the stain has been removed, wipe the surface dry and wax or polish.
Light Cigarette Burns:
Rub the stained surface with scratch-concealing polish. If that does not work you could try rubbing it with a paste of linseed oil and rottenstone with the grain until the burn mark is completely gone.
Try to blot the spilled nail polish as soon as possible while it is still wet. If it has become dry, rub it with fine steel wool dipped in wax. Wipe the surface dry and wax or polish.
