When you are done displaying your banner - in order to maximize your future usage, you must keep it clean, dry, and in a dry cool place while it is not in use. Your outdoor vinyl banner will probably get pretty dirty from all the elements during it's time being displayed. The best method of cleaning your outdoor vinyl banner is to lay it flat (if possible) on a clean area, table or floor. It is recommended that you use a mild dishwashing liquid and luke warm water to rinse. Do not use any harsh abrasive or petroleum type cleaners. Clean and dry each side before storing. You must ensure it is completely dry prior to roll up and storage. Any wetness left on the banner will cause mildew and may ruin some of your banner over time.
Once your banner is completely dry - roll it up with the image outward - to avoid any cracking of the printed side. Do not roll your banner super tight or super loose - this will allow for some breathing room while it is stored. Place your banner back in box and store it flat, not vertical. If it is standing up vertically, it may wilt and warp causing wrinkles over time.
