The straps of a car seat require special care. We take it very seriously. We use the same cleansers (Johnson & Johnson, Dawn, and Dove) to clean the straps. We dilute the Johnson & Johnson and Dawn in warm water. Then we soak a clean microfiber towel in the solution before wringing it out until it is barely damp. Usually, this is enough to get any dirt or stains off of the straps, but if anything is stubborn, we lightly rub a Dove bar on the spot before resuming with the towel. The straps are never submerged in water or taken off of the car seat. It is so important to us that we take the best care of your seats. Of course, we want them clean, but most of all, we want them safe.
