Sutherland Welles Ltd. Di-Citrusol is more than a unique, high performance solvent. It is 100% botanical, earth-renewable, non-petroleum, recyclable, safe and easy to use solvent which has the lowest toxicity of any solvent offered on the market today! It replaces petroleum mineral spirits and other noxious, toxic solvents. It has no Global Warming Potential Number, no Ozone Depletion Potential and is therefore exempt from Europe's carbon tax. It completely biodegrades to form plant nutrients that are naturally recycled, causing no ecological stress. It has a mild citrus scent and when formulated with our Polymerized Tung Oil, a vegetable oil, it creates a totally botanical wood finish. Di-Citrusol can be used in place of any solvent for the specific applications where solvents are required such as cleaning brushes or thinning any Sutherland Welles Ltd. product.
