When cleaning your trade show display one must practice extreme caution, making sure to not further damage any vinyl laminates or allow for any chemicals or water-based solution to get under the vinyl.
The first step in cleaning your graphics is to verify what kind of damage you will be trying to clean. For small stains or light scuffs you can use window cleaner or any light-grade general purpose cleaner. Apply first to a cloth, before working your way up to directly applying it to the stain. For more significant damage avoid using bleaches or other powerful cleaners. This can cause significant and irreversible damage to the outside of the graphic.
When cleaning the graphic avoid scrubbing or rubbing the affected area. Doing this can cause damage to the graphic, causing scratches, gashes or tearing the vinyl. Any damage, even slight, made to the laminate can become worse over time
Additionally be careful when cleaning the edges of your graphics, since the vinyl does not cover this area.
If your cleaning solution gets under the edges it can cause the graphic itself to be damaged, with either bleeding of the ink or causing the graphic and vinyl protective laminate to become detached.Under all circumstances do not ever attempt to dry any stains or excessive cleaning supply with heat, i.e. hairdryers or the sun. This can permanently warp your display.
