5. Maintenance and Care
Keeping your WeatherTech Cargo Trunk Liner clean is simple and helps maintain its appearance and protective qualities. For most cleaning, simply remove the liner from your vehicle, hose it down with water, and wipe it clean with a cloth. For tougher dirt or stains, a mild soap solution can be used. Ensure the liner is dry before placing it back into your vehicle.
6. Troubleshooting
Liner Not Lying Completely Flat:
If your liner appears slightly curled or not perfectly flat upon arrival, this is typically due to packaging. To resolve this:
- Place the liner in a warm area (e.g., direct sunlight) for a few hours to allow the material to relax.
- Alternatively, place heavy, flat objects (like books or small weights) on the affected areas overnight to help flatten the liner.
- Once installed in the vehicle, the liner will typically conform to the cargo area's shape over time with use.
