Baseball cards have been around since the 1870's and are obviously quite fragile, especially the older ones. Because they are made of paper, most cleaning products are far too harsh and can deface your card, affecting the value. A safe way to clean a card is to gently brush away dust with a tissue. Anything more invasive than that could damage your card. If there is a stain on the card, it may be best to leave it as is. A card with a stain will get a better price than one that has been defaced through cleaning.
To care for your baseball cards, handle them as little as possible. An accidental crease can significantly lower a card's value. When you handle your cards, make sure your hands are clean and avoid touching the corners which can easily bend. 'Top loaders' are a popular way to store cards. They are made of clear plastic and store each card separately. That way, the card can be handled and viewed without actually touching the card.
