this study investigated the removal of marks made by 'erasable' marking pens on cotton and cotton/polyester fabrics. data obtained from color difference measurements were analyzed using analysis-of-variance (anova) procedures. results indicated that removal of pen marks was easier from the cotton/polyester fabrics than from the 100 cotton fabrics. the most effective treatment for removal of marks for all fabric types was laundering, instead of following pen manufacturers' instructions. best results were achieved by removing the marks 48 h after application as compared to 24 h or six weeks.
