I spray mine out with a hose all the time and use the floor plugs. I have the marine grade Vinyl. Definitely do not directly spray anything on the dash it’s easy enough to clean properly with a wet cloth only takes about 15 minutes. I haven’t had any problems at all. I also bought the bronco to use as a truck not a show piece so if I get a problem and have to fix it I won’t be too upset. How you choose to clean depends on your risk threshold I guess.
