Sandpaper is great for removing residue and smoothing surfaces. You can use it for a range of tasks around the home. It's especially useful when refurnishing wood furniture or prepping a surface for paint. When sanding any area, make sure to use a sandpaper with the right grit to avoid damaging the surface. Finer sandpaper grit will provide a gentler finish. The more abrasive the paper, the more surface it will remove. Keep in mind that sanding by hand gives you greater control over the process. This allows you to go easier on more sensitive surfaces.
There are a lot more uses for sandpaper than you would think. You can use sandpaper to sharpen scissors and remove rust from tools and knives. You can also use it on unfinished basement stairs to make the edges non-slippery. It even works to remove stubborn grout stains. Keep sandpaper on hand for a variety of tasks around the home.
