Window cleaner (Windex)
Aerosol hair spray
Window clings are a fun, easy way to add a little holiday decor to your home, but often they can become limp and stop sticking well. However, there are a variety of easy ways to refresh decorative window clings that will get them sticking again in just moments. Window clings tend to work best on clean, frost-free windows and will stick longer on windows that get a little bit of sunshine during the day, so take that into consideration when decorating.
Clean the window thoroughly using window cleaner and a rag - avoid using paper towels as they tend to leave too much lint behind for cling-on decorations to stick. If window clings will not stick after the window is cleaned, proceed to Step 2.
Wash the window clings gently with warm water and a tiny bit of dishwashing liquid. Apply them to the window. If they still don't stick proceed to Step 3.
Spray the backs of the window clings with white vinegar in a spray bottle, and wipe them off leaving them just a little bit damp. If clings will not stick to the window, proceed to Step 4.
Use a hair dryer to warm the window and the window clings, then try to apply the cling-on decorations to the window while the window and clings are still warm. If this does not work, proceed to Step 5.
Lightly spray the back of the window clings with aerosol hair spray, and then stick them to the window. However, make sure the window and the clings are clean before trying this.
