I guess the question you need to ask is how did you wash the car? Did you use a pressure washer and hosed down everywhere? You need to be careful with that as you might short wires modules etc... I guess best would be to just blast with air gun everywhere to make sure you got all the water out and plug and blast with air any connections that could of got water.

Sheed, I guess just use common sense and cover any electrical wiring / connections. Probably would be best to check with detail experts.

I washed car with this engine wash spray bottle. I sprayed this on the engine and then let it sit for 10min and washed it with a garden that did not have a lot of pressure. And then I gave the car an entire 12 hours to dry up.I washed car some time so car engine is easily worked.
