Check your sink's shape first; curved bottoms cause most wobbling.
- Use a trivet or towel to stabilize a wobbly colander.
- When buying, choose a colander with a wide, flat base or hanging rim.
- Replace a colander if it's cracked, warped, or has broken feet.
Why does my colander wobble in the sink?
The most common cause is a curved sink bottom. Many sinks slope toward the drain, so a flat-bottomed colander tips. Another cause is uneven feet on the colander. Some colanders have small legs that are not perfectly aligned. Warped metal or plastic from heat can also cause rocking. The colander's rim may not match the sink's edge. Check if the sink is a double basin with a divider. The divider can interfere with a large colander.
How can I make my colander sit flat?
First, inspect the sink's shape. Place a straightedge across the bottom to see if it's flat. If the sink is curved, choose a colander with a wide, flat base. For colanders with legs, gently bend the legs to level it. Use pliers or your hands, but be careful not to crack plastic. Place a silicone trivet or a folded towel under the colander. This creates a stable surface. Alternatively, use a colander that hangs on the sink rim. Some models have hooks that grip the edge. If the colander is warped, consider replacing it.
How can I prevent this problem in the future?
When buying a new colander, check the base for flatness. Look for models with a wide, stable base or rubber feet. Avoid thin metal that bends easily. Measure your sink's basin depth and width. Choose a colander that fits without touching the sides. For deep sinks, a colander with a hanging rim is a good choice. Store colanders carefully to avoid warping. Don't leave them in a hot dishwasher or near a stove burner. If you have a farmhouse sink, consider a colander with a built-in strainer.
When should I replace my colander?
Replace your colander if it has cracks or sharp edges. These can harbor bacteria or cut you. If the metal is badly dented, it may not drain evenly. Plastic colanders that have melted or warped should be replaced. If the feet are broken, the colander will never sit flat. Also replace if the handle is loose or broken. A colander that rusts is a health hazard. If you've tried fixes and it still rocks, it's time for a new one. For a professional, call a plumber if the sink itself is damaged. A cracked sink or uneven installation can cause problems.
