11oz tub - $9.50

Lineco Document Cleaning Pad - $6.50

Lineco's Document Cleaning Pads contain a soft grit-free powder that absorbs and cleans surface dirt from paper. The pads are recommended for cleaning dusty, dirty, or moldy paper items. To use - twist the pad over the paper to produce a thin layer of cleaning powder; then, gently rub the pad over the area to be cleaned; finally, when the powder changes color, carefully brush the residue away with a soft-bristle brush.

100gm package - $17.50

Renaissance Groom/Stick Paper Cleaner is a permanently tacky, non-hardening, processed kneadable natural rubber. It is a gentle, non-abrasive, non-staining, absorptive cleaner of paper and many other archival materials. Graphite, carbon, charcoal, chalk, crayon, dry powder colors, mould spores, dust, dirt, and grease are cleanly lifted off surfaces and held in a 'molecular trap.' Groom/Stick can continue to collect and hold foreign matter until the rubber is several times its original weight.



CLEANERS - Dry


The Gonzo Wonder Sponge - $5.00

Cleans soot, soil, dust, dirt and grime from paper, cardboard, book bindings, oil paintings, wood, leather, etc. Use dry, never wet. Remove dirt and grime with an even sweeping motion, beginning from the top of the surface being cleaned. Exert only moderate pressure. When the Wonder Sponge becomes saturated with dirt and grime, wash with soap and water and allow to dry thoroughly before reuse.



CLEANERS - Leather Dressings


Cellugel for Leather
16oz jar - $17.50

A safe penetrating cellulose-based consolidant for leather affected by red rot (powdery deterioration). Will not harm paper or other book materials. We have found it particularly good for reconditioning badly dried out leather book bindings.



Pecard Antique Leather Dressing
6oz tub - $6.50

Pecard softens old leather, giving it a lasting suppleness. It results in a shine that can be gently buffed (on non-flaking surfaces only). Pecard greatly slows further deterioration of cracking or flaking leather. The dressing is a paste which is of such density that the leather will only absorb as much as it needs.



CLEANERS - Metal



Kroil Penetrating Oil

A penetrating oil than can creep into openings as small as one millionth of an inch. Kroil loosens frozen metal parts, disolves rust and gummed oil, displaces water, provides lubrication, and prevents rust.

200ml can - $17.50

Renaissance Pre-Lim Surface Cleaner is a blend of Neuburg silica chalks in a water/white spirit emulsion. It is mildly abrasive paste for non-scratch cleaning of many surfaces, especially metals and enamels. Pre-Lim prepares the surface perfectly for the use of Renaissance Micro-Crystalline Wax Polish as a protective and visually-enhancing finish. Not recommended for use on lacquered brass surfaces.



CLEANERS - Soap


Vulpex Liquid Soap
8oz bottle - $20.00 or 1 litre bottle - $60.00

Vulpex Liquid Soap is supplied as a dense concentrate of potassium methyl cyclohexyl oleate. It has been used successfully in all branches of professional conservation for the safe and controllable cleaning of materials ranging from feathers, textiles, oil paintings, and leather to wood, metals, shell, ivory, and stone. Vulpex attacks and emulsifies dirt, fats, fatty oils, mineral oils, waxes and hydrocarbons; the resulting dirty emulsions are stable and easily rinsed away. For normal aqueous cleaning, one part Vulpex to six or seven parts water is sufficient; as a spirit soap, one part Vulpex in ten to twenty parts solvent will be found effective.
