Buy an air compressor with say 6 litre tank to keep cost down and use soon after as you can as moist mud will blow off. If you leave and mud dries totally, much harder. Great investment, how every rc owner does not have one is beyond me. Silicon spray is good once cleaned around drive shaft areas etc. Spray and leave an hour then air blow off residue. Simon. Uk.
I tried the new wd40 degrease and it works very well. Used brushes to clean and then compressed air to get everything off. Nice and clean

Spend more time drying your car than washing it. Any water left will rust your screws and fasteners and there goes your great looking chassis. Carefully warm air dry your hardware if you can. WD 40 is good to use. WD stands for Water. Displacement. Lots of people think WD 40. is just a lubricant but it's a lot more, in fact, you can buy WD. 40 with silicone oil in it. Protect your electronics from moisture, takes just a few extra minutes of care while you are cleaning. Preventative maintenance is important with RC cars.

Agreed, avoid cleaning with a hose pipe... eh ? I'd never do this... asking for trouble, it's an rc car with electronics and a battery. They don't go together.

You spray WD40 on your electronics?

Water isnt the problem, water under pressure is.
If your overly worried about it, keep an eye on bearings. Id had more bearings get trashed from poor construction and dirt than I did in fresh water though. Throw your receiver in a balloon or stuff it with dielectric grease if thats a worry. Most any esc is perfectly fine submerged; servos are usually fairly well sealed - though you can open them and stuff them with dielectric grease it too.
Everything in the rc is splash proof at minimum.
Not saying water is the best way to clean these, Im saying a little water here and there wont hurt anything. If you feel uncomfortable with water in your rig, then don't. Compressed air alone is fine for 99% of the normal clean ups. And a brush will often tackle that last 1%.
Side note, I started some tests with nylon-6 filament, soaking them in wd40, water, oil and simple green to see any cause a noticeable difference. No idea how long it will take to see some sort of result. Stay tuned!

Shut up and take all of my money. I need this. I don't have an air compressor at my condo, but have one at the farm. Where can I get one?

If, the mud is already dry and I have some laundry to do I'll leave my truck on top of my water tank for the house. When I'm done with my laundry the dirt literally just falls off of my truck. Every time my water pump turns on the tank vibrates at a high frequency. I came up with the idea after watching an episode of Oak Island where they vibro-cleaned artifacts.
not directly on the electronics

I am not a water guy no way. I use baby wipes which are cheap as, a brush and compressed air and my rigs come up beautifully every time..

This is a 3d printed blower fan but you can also get ones on Amazon for really cheap. However a air compressor will perform way better then this. This works with a fan that just moves the air through a nozzle which makes it have a little bit of pressure. An aircompressor actually pumps air in a reservoir and pressurizes it.

Take your point, each to their own i guess. Air compressor is the way and a brush and silicon wd40 to finish. Still learning...Yet tons of us do it and have for many a years with great success...So strange..
Let nylon6 filament sit in baths of water, wd40 with solvent, wd40 letting solvent dry twice weekly, water, simple green to see any difference. Also had a sample left to open air and one that was dried to ~4%.
Tried to bend to the point of causing a plastic deformation or stress fractures/white marks. I could not cause any stress fractures with my hands while bending, and all samples deformed plasticly to about the same extent, except the water logged one retained slightly more bend.
Un-scientific break strength with a bench vise and my muscles. I could not break any of the filaments except the dry sample. It would comparatively quickly elongate near the vise and break near my limit of pulling.
The water logged sample seemed to have more elasticity than the rest by a small amount. The one soaked in wd40 and solvent was slightly bendy-er, even after let dry overnight.
Perhaps wd40 does make softer when used excessively but not with normal, light use. Dry nylon seems more brittle, and this was the only thing I could verify from others testing. Some atmospheric humidity appears to be good for nylon. Water logged nylon, unclear if any addition benefit or detriment.
Otherwise, I could not tell the difference between any samples. I know it's pa6, a small sample and short duration, but if I didn't see any noticable issues in that time, I'm not worried about the nylon on my rig within a reasonable time frame.
