The 3 Berries to Wash Right Away

The choice to wash berries right after you bring them home comes down to how well they can handle it and how badly they need it. The berries listed below are sturdy enough to wash before heading into the fridge. They also benefit from a dip in treated water to prolong their shelf life. As for berries picked from a backyard bush or an obliging field, cleaning them right away removes any animal friends or unwanted debris.

1. Strawberries
Whether you plan to devour these sweet red gems immediately or save some for later, go ahead and wash them now. For added insurance to keep them around longer, use a vinegar and water solution or a hot water bath.

2. Blackberries
Go ahead and wash these jewel-colored beauties right away. Like strawberries, blackberries can also benefit from a longer shelf life when washed in a vinegar and water solution or a hot water bath—just make sure to dry them really well before storing.

3. Huckleberries, Mulberries, and Other Backyard Berries
A cousin of the blueberry, deeply colored huckleberries, along with mulberries and service berries, can and should be washed right away to remove any insects, dirt, and grit.

The 3 Berries to Wash Just Before Eating

Whether they’re too fragile or come with their own built-in protection in the form of a waxy bloom, these berries don’t need a bath until you’re ready to eat them.

1. Raspberries
These sweet berries are particularly fragile, with thin skin that easily soaks up liquid, making them more prone to mold and spoilage. So the best way to keep them fresh and extend their shelf life even longer is to wash just before eating, and no sooner.

2. Blueberries
Unless you plan to eat them immediately, there’s no need to jump the gun on washing blueberries. These small summer fruits last longest when stored in the back of the refrigerator, and washed just before eating.
