Our exclusive roller cleaner, LOR-326, is a must for prolonging the useful life of your rollers. While you can use LOR-326 to occasionally deglaze and condition your press rollers, we recommend that you use LOR-326 everyday in place of your regular press wash. LOR-326 will deep clean the ink from your rollers and because it is a non-petroleum cleaner, it will never swell or harm any brand of rollers. LOR-326 is used without diluting but is very concentrated and actually cost less than regular press solvents. LOR-326 is sold in single quart bottles as well as 12 bottle cases.
