When renovating and restoring old furniture, also historic, remnants of old varnish or polish must be carefully sanded with fine-grained sandpaper or scraper. It is easy to do by hand on the flat, exposed planes. A special delta orbital sander can be used in hard-to-reach places on curves and hollows. The special shape of its foot enables grinding in corners with sandpaper of various thicknesses, fastened with Velcro.
