Yes it will, the virus doesn't survive long outside the body, it may not be the best way as it can survive more than 24 hours in some surfaces, but it is way better than nothing. Note that spraying them with alcohol is also recommended.

From the research I've read, it seems that it can survive 2-3 days on plastic, and potentially a lot less on other surfaces. The cold air in the refrigerator probably does extend its lifespan a bit. I normally wash produce anyway, so it's more of an additional precautionary measure than a single line of defense.
