I have heard people talk about after you clean your truck spray it with wd-40 an then the next time you run it you can easily blow off the dirt, does that really work? Also what is the best way to clean a truck besides disassembly?
I've found that WD-40 makes dirt stick, even with trying to blow it off. Most people use nitros in warm weather, also meaning they don't see much water, and the only time you need to use WD-40 in to repel water, becuase WD-40 IS NOT A LUBRICATNT! The best way to clean the truck of, IMO, is to use a mixture of 50% water and 50% Simple Green, let it sit for about 5 min, then blow it off with compressed air. It takes off the oil, dirt, and nitro easly. It also makes the plastic and rubber parts look like new! Hope this helps!
i use both simple green n water 50/50 or sometimes wd-40 for a good shine after.. key is to have good air pressure when blowing cleaners out..regardless what ever u use its gonna get filthy after a good bash...
You can easily blow off the dirt next time if you wait long enough, as the water in the dirt will have been displaced and the dirt will be very loose. But it's a bit random and it's best to clean it right after a bash, not let it sit, at least not if it's wet dirt.
Just cover up electronics and air filter and wash it with simple green and water, and go over it with some wd40 afterwards to displace water and protect the metal against rust. Just don't spray directly on bearings, as you don't want it penetrating them as it can dry out the oil.
If the dirt is very sticky or hard, you can use wd40 before the simple green process to penetrate it and make it looser asap. Just make sure to dry it up with air pressure or dry, ventilated and warm area, so it don't rust.
WD40 has lubrication qualities, but those qualities will fade fast and only leave a protective rust surface. It's mostly for removing grease/dirt/paint/sticky crap and whatever it can penetrate. And the lubrication is only good for simple moving parts like a lock or anything that's not generating a lot of friction.
Thanks for the information.
A little off subject here SlayerNor you said just don't spray directly on the bearings,so doesn't that mean people shouldn't use WD40 for after run because it going to get WD40 on the bearings in the motor.
You're safe using WD40 as after run treatment.
I just got a Slayer Pro 4x4 and the instruction manual that came with the truck says specifically to use WD-40 as after run oil.
WD-40 is ok as a after run oil. The "wd" in WD-40 stands for water displacment, and that's what you need in a after run oil. But, it you use a true oil, it will displace water AND provide lubrication. Just my .02 cents
WD-40 does leave a protective lubrication surface as well. It's not a lubrication good enough to handle any high level of friction, but more than good enough to protect it against rust.
True, is does have "some" lubrication properties, but, then again, almost anything, even butter can lube better then WD-40. WD-40 is alot better than water, or say grit, but there is much better options for a lubricant you can use instead of WD-40.WD-40 does leave a protective lubrication surface as well.

Afterrun treatment is not about lubrication, it's about displacing water first then leaving a protective surface against rust. WD40 is FAR underrated at this point. Even after it appears to dry, these ingredients stays on the metal very well and is only weak to external conditions such as starting the engine again or any high level of physical friction. That's why it's not suitable as a lubricant beyond very low friction purposes, such as door locks and sqeaky joints.
Comparing it to butter and grit is nonsense. But yes, there are alternatives but it still does the job. WD40 is a "multitool" so it's not best at anything, but it just happens to be very suitable for keeping rust out of nitro engines.
