Loosening a sticky roller or guide
Instead of fighting sticking drawers, take about two minutes per drawer to clean and lubricate them so they'll glide in and out with the touch of a finger.
For drawers fitted with rollers and guides (Photos 1 and 2), wipe them clean and spray the rollers with a drying-type silicone lubricant that doesn't attract dust. Look for the type that can be sprayed on plastic and rubber as well as metal.
Most dresser drawers don't have rollers and guides. To renew their smooth action, use a rag to clean out old dust and wax. Then rub hard wax (candle or paraffin) along the drawer edges and center guide.
