配方類型： SOAPS AND DETERGENTS
配方說(shuō)明： Dried Paint-Brush Cleaner
配方組成： Butanol/5
"Aerosol" C-61/10
Mineral Spirits/40
Xylene/45
配制方法： The brush caked with hard dry paint is soaked in the mixture for a while and then worked up and down to aid the penetration into the caked paint. The soaking and working may be repeated several times if the paint is very hard and dry. When the old paint has soaked out of the brush, it is rinsed in clean, warm water, finally washed in soapy water and rinsed again, then hung up to dry. After drying, the bristles have the appearance and feel of those in a new brush.
