Wipe gently: Use a soft damp cloth on the PVC face. Skip harsh cleaners because they can dull the print. Dry the sign right after.
Store flat: Keep props flat or upright in a box. Heavy items on top can bend the board.
Protect from heat: Do not leave signs in a hot car or in long direct sun. PVC can soften and warp in high heat.
