Groom Stick is a novel form of natural rubber with specific properties combining to create a surface dry-cleaner of high efficiency. The rubber's natural structure has been modified to make it permanently soft, kneadable and strongly tacky. Moisture, solvents and chemical additives have been excluded. As a non-abrasive, non-staining cleaner of paper and other library materials, Groom/stick gently but positively picks up a wide range of foreign matter. Graphite, carbon, charcoal, chalk, crayon, dry powder colours, mould spores, dust, dirt and grease are cleanly lifted off the surface and held in a 'molecular trap' from which there is no escape! The process is fast and smear-free. It is demonstrated by lightly rolling a Groom/stick 'cigar' across a freshly-printed newspaper. Excess print ink is removed instantly - without blurring the print or soiling adjacent clean areas. Ordinary solid or granular rubber/resin erasers abrade, smudge, crumble or produce clinging debris. Groom/stick sacrifices nothing of itself, leaves no dirty fragments to brush away (or mould spores to regenerate in concealed areas) and is always ready and clean to use. Sold in 100gm packs.
