Quick answer

First, clean the pad and the wall with a damp cloth and let both dry completely. If the pad still won't hold after two tries, replace it with a fresh nano-adhesive pad. A pack of Gecko Run replacement pads gives you 40 new pads, so keep spares on hand for quick swaps during play.

Why Gecko Run pads lose their stick

Nano-adhesive pads hold by creating thousands of tiny contact points with a smooth surface. Dust, lint, fingerprints, and repeated peeling all reduce those contact points. A pad that feels slightly slick or has visible fuzz on it is usually dirty, not worn out. Clean it before you decide to replace it. If the pad is torn, stretched, or has lost its shape, cleaning won't help and a new pad is the right move.

How to clean and reapply a pad that still has life

Use a mild soap and water solution on a soft cloth. Wipe the pad gently, then wipe the wall or surface where you want to stick it. Rinse the cloth and wipe again with plain water to remove soap residue. Let both the pad and the surface air-dry completely. Press the pad firmly for a few seconds when you reapply it. Avoid touching the sticky side with your fingers during the process.

When to stop cleaning and replace the pad

If you have cleaned and dried the pad twice and it still slides or falls within a few minutes, the adhesive layer is done. Replace it. The same goes for pads that have picked up permanent grit, paint flakes, or hair that won't rinse away. Pads used on textured or painted walls may wear out faster than pads used on glass or smooth tile. If you run a large marble run, keep a few replacement pads within reach so a single failure doesn't end the session.

Step-by-step: replace a Gecko Run pad

  1. Peel off the old pad: Lift one corner and pull slowly. Do not rip it off quickly, because that can leave adhesive residue on the plastic part. Checkpoint: if the old pad tears and leaves sticky bits behind, wipe the part clean before continuing.
  2. Clean the plastic part: Wipe the mounting surface with a damp cloth to remove old adhesive, dust, or oil. Let it dry completely. Common mistake: sticking a new pad onto a damp or dirty surface, which weakens the bond immediately.
  3. Peel a fresh pad from the sheet: Use your fingernail to lift the pad from the backing. Try not to touch the adhesive face with your fingers. Checkpoint: handle the pad by its edges only.
  4. Press the pad onto the part: Center the pad on the plastic mount and press firmly for several seconds. Make sure the edges are flat. Common mistake: pressing too lightly, which leaves air pockets under the pad.
  5. Stick the part to the wall: Press the part against a clean, smooth surface and hold for a few seconds. Test with a gentle tug before adding marbles. Checkpoint: if the part slides, clean the wall and try again with a new pad.
