A cast-iron-bathtub is a beautiful addition to any bathroom. These bathtubs have been in existence for many years. Some cast-iron-bathtubs are true antiques and some are manufactured to look like they are antique. cast-iron-bathtubs are more expensive than fiberglass bathtubs, but they are most definitely worth it. cast-iron-bathtubs are usually finished with a porcelain enamel coating. The porcelain coating is susceptible to chips, crazing and wearing of the finish. The last thing you want to do is to clean your cast-iron-bathtub with products that will accelerate the wear on the finish. It is very important not to use any abrasive cleansers such as scouring powders, steel wool, white vinegar or lemon. The abrasives in the scouring powders and steel wool will scratch and damage the finish on the bathtub and ruin it. The acid in white vinegar and lemon will also damage the porcelain finish. Regardless whether or not you have a beautiful antique claw footed bathtub or a new cast-iron-bathtub, clean and care for it properly so you will have it for years to come.
