Winsor & Newton has always been core to the world of art materials. We proudly maintain our pledge of manufacturing “The World’s Finest Artist’ Materials”. This is as true now as it was when our company was founded in 1832, and we take our relationship with the artist very seriously. Our founders, Henry Newton and William Winsor were involved with the leading artists of their time - J.M.W Turner for example - and to this day, we strive to keep up with the latest developments in the art world and take an active interest in what artists say. We have built our reputation on the quality and reliability of our products, combined with continual product development, improvement and innovation. However, while keeping true to the principles laid down by William Winsor and Henry Newton in the 1800’s we actively embrace new ideas, new technologies and search the world for the best raw materials available. Winsor & Newton Brush Cleaner is a water-miscible solvent that removes dried oil, alkyd & acrylic paint from brushes. Simply soak your brushes in the cleaner overnight & scrub if necessary. Cleanable with water.
