We use a more sensitive method consisting of the use of special washes. Due to the presence of active chemicals in their composition, these washes quickly penetrate the structure of the old paint or varnish and destroy them. After that, the resulting mass is removed with special spatulas or brushes. Washing is used to clean threads and demanding surfaces. In places where removing varnish and paint is physically impossible sanding is used.
