Some silica gel units can be "refreshed" by plugging them into a 110v socket whenever the color indicator advises. This gently heats the gel and drives off the moisture, so do this somewhere other than your camper!((https://www.eva-dry.com/frequently-asked-questions)) | Some silica gel units can be "refreshed" by plugging them into a 110v socket whenever the color indicator advises.
