Grumbacher - Grumtine

Grumtine

Clean brushes with citrus-scented medium that outperforms turpentine

Grumtine combines the thinning power of traditional solvents with the cleaning effectiveness artists actually need in the studio. This citrus-based medium thins oil colors more effectively than turpentine while doubling as a brush cleaner that cuts through dried paint without harsh chemical odors. The natural orange rind scent makes extended painting sessions more pleasant, particularly in studios with limited ventilation.

Add Grumtine directly to oil colors for controlled thinning or blend it into custom mediums to adjust viscosity and flow. The formula maintains pigment integrity while providing the fluid consistency needed for glazing, underpainting, or detail work. When painting concludes, soak brushes thoroughly in Grumtine to dissolve accumulated color, the same solvent that thinned your paint efficiently removes it from bristles.

Grumbacher's original formula delivers consistent performance across both applications. You eliminate the need for separate thinning and cleaning products, streamlining your setup while maintaining the solvent strength required for professional oil painting. Studios working with traditional oil techniques gain a versatile medium that handles daily painting demands and cleanup with equal effectiveness.
