Winsor & Newton Sansodor is a good alternative to white spirit and other thinners. Used as a both dilutant and brush cleaner, Winsor & Newton Sansodor has low odour and flammability.
It is particularly useful due to its low evaporation properties, making it very good at controlling alkyd and oil colours.
Sansodor is available here in 75ml, 250ml and 500ml bottles. Caution: Please follow manufacturer safety instructions carefully. Not suitable for use by children.
