Washing eggs is a common practice for backyard poultry keepers, but doing it wrong can push bacteria into the shell and make eggs unsafe. This guide follows the USDA’s recommended method for washing eggs in warm, running water with an unscented detergent, then drying and refrigerating them promptly. It’s the only way to clean eggs without increasing the risk of Salmonella and other foodborne illnesses.
Ingredients
- Freshly collected eggs (as many as you need to wash)
- Warm running water (at least 90°F / 32°C, but not hot)
- Unscented dish soap or commercial egg wash detergent (a few drops per dozen)
- Clean, dry paper towels or a clean dish towel
- A clean bucket or bowl (optional, for holding eggs)
Instructions
- Gather your eggs. Collect eggs as soon as possible after laying, ideally within an hour, to minimize dirt and bacteria buildup. Discard any cracked or leaking eggs—they are not safe to wash or eat.
- Prepare your washing station. Place a clean bucket or bowl near your sink. Ensure you have a steady stream of warm running water (at least 90°F / 32°C). The water must be warmer than the egg’s internal temperature, which is usually around 70°F (21°C), to prevent the egg’s contents from contracting and pulling bacteria through the shell pores.
- Wash each egg individually. Hold one egg under the running water. Apply a small amount of unscented dish soap or a commercial egg wash detergent to the shell. Gently rub the shell with your fingers or a soft brush designed for eggs. Do not soak eggs—soaking allows dirty water to be drawn into the egg. Use only running water, not a still basin.
- Rinse thoroughly. Continue holding the egg under the running water until all soap residue is gone. The shell should feel clean and slightly rough, not slippery.
- Dry the eggs. Place the washed egg on a clean paper towel or dish towel. Gently pat it dry. Do not rub, as rubbing can remove the bloom (the protective coating) further and increase the risk of contamination. Let the eggs air-dry for a few minutes on a clean rack or towel.
- Refrigerate immediately. Once dry, place the eggs in a clean egg carton or container and put them in the refrigerator. The USDA recommends storing washed eggs at a temperature of 40°F (4°C) or below. Use them within 2-3 weeks for best quality.
Tips
- Wash only when necessary. The USDA advises that eggs are best kept unwashed until right before use, as washing removes the natural protective bloom. If you wash at collection, you must refrigerate promptly and use within 2-3 weeks. If eggs are only lightly soiled, consider dry cleaning with a brush or cloth instead of washing.
- Use warm water, not cold or hot. Cold water causes the egg contents to shrink, pulling bacteria inward. Hot water can cook the egg white and damage the shell. The water should be at least 90°F (32°C) but not uncomfortable to the touch (around 100°F / 38°C is fine).
- Never use bleach or vinegar. These can damage the shell and are not approved for egg washing. Stick to unscented dish soap or a commercial egg wash detergent that is food-safe.
- Dry eggs before refrigerating. Moisture on the shell can promote mold growth. Always dry eggs thoroughly before storing.
Serving Suggestions
Washed eggs are perfect for any recipe that calls for fresh eggs—scrambled, fried, poached, or baked. Use them in omelets, quiches, cakes, or simply boil them for a snack. Since they are refrigerated, bring them to room temperature before cooking for more even results, especially in baking.
Variations
- Dry cleaning: For eggs with light dirt, use a dry sponge, fine sandpaper, or a special egg brush to remove debris without washing. This preserves the bloom and allows storage at room temperature for up to 2 weeks (if they are unwashed and kept in a cool, dry place).
- Commercial egg wash: If you have many eggs, consider using a commercial egg washing solution that is specifically designed for eggs. These are available at farm supply stores and often contain a sanitizer that is safe for food contact.
- Water temperature test: Some keepers use a thermometer to ensure the water is at least 90°F (32°C). If you don’t have a thermometer, the water should feel comfortably warm, not hot, on your wrist.
Storage and Reheating
Washed eggs must be refrigerated immediately after drying. Store them in the original carton or a clean container in the main body of the refrigerator, not in the door where temperatures fluctuate. Use washed eggs within 2-3 weeks for best quality. If you have hard-boiled eggs, they can be refrigerated for up to 1 week. Do not freeze whole raw eggs in the shell; if you need to freeze eggs, crack them into a freezer-safe container, beat lightly, and freeze for up to 1 year. Reheat cooked egg dishes to an internal temperature of 165°F (74°C) before serving leftovers.
Frequently Asked Questions
Is it safe to wash eggs with just water? The USDA recommends using a detergent or egg wash to remove dirt and bacteria effectively. Water alone may not remove all contaminants, and the friction from rubbing with soap is more effective.
Can I wash eggs in a bowl of water? No. Soaking eggs in a bowl of water is not recommended because the water can be drawn into the egg through the shell pores, carrying bacteria with it. Always use running water.
Why do store-bought eggs look clean but my farm eggs are dirty? Commercial eggs are washed and sanitized at the processing plant, which is why they look clean. However, this process removes the bloom, so they must be refrigerated. Your farm eggs may be dirtier because they are not washed, but you can clean them using this method.
Can I wash eggs and then store them at room temperature? No. Once you wash eggs, you must refrigerate them. The washing process removes the protective coating, making the eggs more susceptible to bacteria. Unwashed eggs can be stored at room temperature for up to 2 weeks, but washed eggs must be kept cold.
What if my eggs are very dirty? If eggs are heavily soiled, wash them as soon as possible. Use a soft brush to gently scrub away caked-on dirt while holding the egg under warm running water. If the egg is cracked or leaking, discard it.
Can I use vinegar to wash eggs? Vinegar is not recommended. It can weaken the shell and may not effectively remove bacteria. Stick to unscented dish soap or a commercial egg wash.
