Products For Cleaning Your RC
 

I don't know where I first saw it, but Simple Green Foaming Crystal Industrial Cleaner & Degreaser is getting a very good "rep" around the interwebs.

I had to try it along with trusted plastic rejuvenator WD-40 Specialist Silicone Lubricant. Well, I'm hooked! It's a good thing, 'cause I couldn't find the single cans of the foaming stuff anywhere... I had to buy a of it.

I normally don't take my RCs out in muck. Once in awhile I'll get a wild hair up my rear end, and go for it. It was above 50*F outside, and there were leaves covering a corner of my track. Just so happens that the corner was filled with water. A couple of rounds later... it was too late.

Fifteen minutes later, and walking back to the house, I tried to sling off the mud as much as possible... WOT through the grass.

This is the part I hate... taking off the lid to see what's inside.

I really wish I had gotten some shots of the Simple Green doing it's thing... foaming away the crap, but my hands were covered in crap. Mind you, I pushed off the large chunks of caked on crap before I started spraying the Simple Green in a can. I don't have a waterproof servo, so I took care not to oversaturate it. After a round of the foaming Simple Green, and air (lots of air), I hit the chassis with another round of foaming Simple Green. Letting the foam bubble away for 10 minutes, and blasting the nooks and crannies with lots of air, I sprayed everything down with some WD-40 Specialist Silicone Lubricant.

I wait for somebody to rebrand this foaming Simple Green stuff into a RC specific product and jack up the price.

I've always used simple green and alcohol 50-50 mix in a spray bottle. Small paint brush and then air compressor. Foaming simple green sounds pretty good. Might have to try it.

These are my all time favorite products for cleaning my RC's:

That never gets old!

It is a useful product to clean stuff like you used. I want to mention there is also a good cleaner like car guys, chemical guys, and others those are safe and perform well.
