Lubricate Sliding Doors with Silicone Spray

The Problem

Sliding door grinds and is hard to open.

The Hack

Vacuum track to remove debris. Spray silicone along full track length. Slide door back and forth.

Why It Works

Silicone creates ultra-slippery film that repels water. Unlike WD-40, it doesn't attract dust.

Pro Tips

• Use silicone, NOT WD-40 — WD-40 attracts dust
• Spray the rollers too
• Every 6 months for maintenance
• $5 can lasts years
