If you want to protect the quality and integrity of your mattress, you need to take care of it. Basic maintenance of a mattress is not that hard and can effectively increase its lifespan by a long margin. First and foremost, you should always use a mattress cover with your mattress to protect it against dust or dirt. When you spill drinks on your new mattress, it is a good idea to address the issue immediately. If the spillage dries before you decide to clean it, it might stain your mattress forever. As a general rule, however, it is better not to drink or eat on your bed as it risks getting it dirty.
