Quick Answer

Unbox your Monster Jam Mystery Mudders 2-Pack and wash the trucks with warm water to reveal the hidden graphics. If the mud doesn't come off easily, try a gentle scrub with a soft brush. If the graphics are still unclear, the truck may need a second wash or the mud layer might be too thick.

What to Expect in the Box

The Monster Jam Mystery Mudders 2-Pack includes two 1:64 scale die-cast trucks covered in a washable mud coating. Each truck is a mystery until you clean it. The set also includes official BKT tires and an authentic chassis, so the trucks look and feel like the real Monster Jam vehicles. The mud is designed to be washed off with water, revealing the detailed graphics underneath.

How to Wash Your Mystery Mudder

Fill a bowl or sink with warm water. Submerge the truck and gently rub the mud with your fingers or a soft cloth. For stubborn spots, use a soft toothbrush. Do not use soap or harsh cleaners, as they may damage the paint. After washing, dry the truck with a towel. The graphics should be fully visible after one or two washes.

What If the Graphics Don't Show?

If the mud doesn't come off completely, the truck may need a longer soak or a second wash. If the graphics are still faint or patchy, the mud layer might be too thick or the truck may have a manufacturing variation. In that case, you can try a gentle scrub with a soft brush. If the issue persists, contact Spin Master customer support for a replacement.

Troubleshooting Your Mystery Mudder

  • Symptom: The mud doesn't come off after washing. Try a longer soak or a gentle scrub with a soft brush.
  • Likely Cause: The mud layer may be too thick or the water may not be warm enough. Use warm water and let the truck soak for a few minutes before scrubbing.
  • Corrective Action: Wash the truck again with warm water and a soft brush. If the graphics are still unclear, the truck may have a manufacturing defect. If the problem persists, stop washing and contact Spin Master customer support for a replacement.
