You should try and remove marks and stains or marks as soon as possible. Delay may make it impossible to avoid permanent staining.
First try to absorb as much as possible. Sponge or spray with dry-cleaning fluid. Apply warm water and vinegar. Rinse with water. Keep repeating until the stain is gone. Blot dry.
Remember: When attempting to remove a mark, avoid concentrated rubbing on a particular area, as this is likely to produce abrasion damage. Always clean from the outside to the centre of a stain. This will minimise spreading of the mark or stain.
