Washboards manufacturing is a niche industry that specializes in producing washboards, which are traditional laundry tools used for scrubbing clothes. The process involves cutting and shaping wood or plastic into a rectangular shape with ridges on one side. The ridges are what make the washboard effective in removing dirt and stains from clothes. The washboards are then finished with sandpaper to smooth out any rough edges and make them ready for use. This industry has seen a decline in demand due to the availability of modern washing machines, but there is still a market for washboards among those who prefer a more traditional approach to laundry.
