PRINTED MATTER PURIFYING SPONGE (PURUS) 1 kg

Scope of use: PURUS is suitable for cleaning of paper books, book edges, including colour and goldplated ones. For leather bookbindings it is suitable with an increased caution. It is not suitable for glossy surfaces (as it forms maps).

Directions for use: dust off the books - by vacuum- cleaning. Carry out the final cleaning with PURUS using fluent strokes in one direction. PURUS will crumble away during the cleaning. Vacuum the remains. Remove continuously crumbs and dust layers formed on PURUS during cleaning.
