It's no secret that a bathroom remodel is one of the projects that will yield the best bang for your home-improvement buck. But if tight finances postpone a full-blown or even a partial bathroom remodel, there are still a multitude of easy, cost-effective improvements you can do yourself to make the space more attractive and livable. One of the best and most economical means of sprucing up an old bathroom is cleaning. It's something that most people can do, it doesn't cost much, and we have yet to see a bathroom that couldn't benefit from it. MILDEW BE GONE Mildew is often a problem in bathrooms because of the moisture that's present. For many years we have been using a homespun formula developed by the USDA Forest Products Laboratory to remove mildew on painted and washable surfaces, inside and out. Mix 1/3 cup of powdered laundry detergent and 1 quart of liquid chlorine bleach into 3 quarts of warm water. Add the bleach to the water first and then the detergent. Eve
