Short answer: toy-grade RC cars are not waterproof, and most are not even water-resistant. A splash through a puddle is usually survivable; driving in rain or through a wet lawn usually is not. Here is what fails, what survives, and how to dry a car that got wet.
| Label | Means | Found on |
|---|---|---|
| Waterproof | Sealed electronics; can be driven through water | Hobby-grade cars over PKR 60,000 |
| Water-resistant / splash-proof | Covered receiver; survives spray, not immersion | Some 1:12 off-road trucks |
| No label | Open circuit board; keep dry | Nearly every toy car under PKR 15,000 |
Usually fine: one quick puddle splash on a driveway; light drizzle for a minute. Usually fatal: driving on wet grass (water is thrown up into the chassis continuously), driving in rain, washing with a hose, and the spray-and-smoke stunt cars — their water tank is meant for a fine mist from the top, not for driving through water.
A dry paintbrush for dust, a damp cloth for the body only, compressed air for the chassis. The maintenance checklist covers the full routine. If you want a car that genuinely handles mud and puddles, look at the off-road trucks with a covered receiver and accept that 'resistant' still means 'dry it after'.
Toy-grade cars cannot. A splash is survivable if the car is switched off and dried quickly; driving through water or on wet grass usually kills the receiver or rusts the motor.
No. Rain enters through the chassis gaps and shorts the receiver. Wait for a dry surface — even a damp driveway throws water up into the car.
Remove the battery immediately, open all hatches, and leave it in a warm dry room for 48 hours with a fan. Then test. Rice does not help.
