Anything wrong with just spraying it off with a light stream of water? Any products that can help move it along?

 

I sprayed mine with alumium stripper (smells like rotten egg) soak a minute or two and blast the rad. with the hose row by row and watch the crap come right out the back side.

 

Don't forget that you drive through the rain...the radiator isn't shielded from this; you should be fine with water.

The aluminum stripper sounds harsh fr routine use, but I know jack squat about this sort of thing.

I imagine, though, that you could always use (my favorite cleaning agent ever) Simple Green. If you decide to be especially cautious, though I don't think it's necessary, you could dilute it all the way down to a 4:1 ratio. After that, I don't think you're helping anything more.

I'm not too sure, but there's something bugging me along the lines of corrosion and SG on aluminium. I don't really know much about he reactions betwen various chemicals and Metals. But, I'm sure somebody else here knows.

Good luck. Hope I've helped some.

 

I'm running an experiment right now on my truck. I got a couple of the cheap washable foam cut to fit air conditioner filters at Lowes. I placed them on the front of my radiator and tywraped the tops to about 4 points to keep them suspended. When the engine is running the fan pulls them flat against the front of the radiator. So far, I haven't noticed any elevation of engine tempertures, but I do have a great bug collection started. I plan to remove the filters and wash them every 30 days or so if needed.

 

I'd be a little leery of using an aggressive cleaner like aluminum stripper. That rotten egg smell probably comes from Sulfuric Acid. You might get your radiator clean. Then again you might disolve it too. If you do decide to use something like this, rinse quickly and completely.

 

yea water will not hurt it, just dont blast it with a pressure washer or hose because you will bend the metal.

 

You could also use some HVAC coil cleaners that are biodegradable:
Recoil is one of them that's safe for plastic and paint. Most people would have no use for this quantity, but maybe a few could go in on one, or whatever.

yeh u should be good with the water from your home spout and a spray nozzle. Pressure washers work good just as long as you stay about two foot away. Just be careful a pressure washer will crush all the fins and they're a pain to straighten.

 

I just rinsed it off today. I used one of those garden nozzles, that has the angle spray setting. I stood about three or four feet away and sprayed. Worked pretty good. Thanks for all the help.
