Home brew Mudd Off recipe needed

[cvra]

I've seen it on here before about using baby oil and water for keeping the mud of the car. What ratios are being used. Also open to any other home brews for keeping the mud off the car.

99 cent bottle of baby oil in a 2 gallon sprayer has always worked for us.

I got a hand pump air sprayer from NAPA and I use a 50/50 mix of baby oil and wd-40.
