Naphtha

Naphtha

Definition: Naphtha is a volatile, flammable solvent commonly used in picture framing and conservation for dissolving adhesives, thinning certain coatings, and cleaning non-porous surfaces. It evaporates quickly, leaving minimal residue when used correctly.

Overview

Naphtha is valued in framing and conservation for its ability to break down old glues, remove sticky residues, and clean metal or glass surfaces without causing long-term damage. Its fast-drying nature makes it useful in situations where rapid evaporation is desired.

Uses in Framing

• Removing old adhesives from frames, glass, or backing materials.
• Cleaning residue from metal hardware or glazing.
• Thinning certain finishes or waxes for easier application.
• Surface preparation before applying conservation treatments or new adhesives.

Safety Considerations

• Highly flammable - always use away from open flames or sparks.
• Work in a well-ventilated area to avoid inhalation of fumes.
• Wear protective gloves, such as Nitrile Gloves, to prevent skin contact.
• Avoid prolonged exposure; use protective eyewear if splashing is possible.

Best Practices

• Test on an inconspicuous area before applying to artwork or frame surfaces.
• Apply with a clean, lint-free cloth or soft brush.
• Dispose of used cloths safely, as they can spontaneously combust if left in a pile.
• Store in a tightly sealed container away from heat sources.
