Tetrion Graffiti Remover is a fast and effective multi-surface cleaner designed to remove unwanted spray paint, marker pen, ink, and crayon from various surfaces including brickwork, glass, wood, and metal. It is water washable and leaves no trace. This versatile formulation can also be used to remove permanent pen from whiteboards and is suitable for both smooth and rough surfaces. Its clinging agent makes it ideal for use on vertical surfaces, ensuring maximum contact time. For application, always wear eye protection and gloves, ensure good ventilation, and test in a small area first. Shake the bottle well, hold upright, and spray from 30cm away onto the affected area. Allow it to work for 5-10 minutes, or up to 30 minutes if necessary, ensuring the mixture does not dry. On smooth surfaces, wash down with water and wipe with a clean dry cloth. On rough surfaces, work the product into the surface with a stiff brush before flushing with plenty of water. Repeat if necessary. Store in a cool, dry place with the trigger in the ‘off’ position, and always store and transport upright.
