How should I apply window clings to avoid bubbles?

A clean surface and slow, steady pressure are the whole secret to a bubble-free window cling. Rushing or skipping the cleaning step is what traps air underneath.

• Clean the glass thoroughly with glass cleaner and let it dry fully first.
• Start from one edge and lay the cling down gradually rather than all at once.
• Use a squeegee or credit card to smooth outward, pushing air toward the edges.
• Work slowly and lift-and-reset any section that catches a large bubble.

Any small bubbles that remain usually vanish within 24 hours as the cling settles against the glass.
