The table on the container says the max dilution is 1:13 to prevent corrosion to metals. Is this what most folks go by or are stronger mixes being used for radiator cleaning without harm to the aluminum fins?

It actually says 1:3 -- and that's what I use.

It does say 1/13. That is what I use and it works very well. I have posted elsewhere on the forum my procedure that FREIGHTLINER recommended.

I use 3:1 ratio and it cuts the road grime very well. It takes a pH above 10 to damage aluminum so nothing to worry about and you need to rinse it down well anyway after spraying the extreme green.

3 parts water 1 part cleaner

I use a power washer to get rid of all the road grime from radiator / engine / transmission. Just did it today. I did use some engine degreaser on the motor to clean it up for the slobber tube canister installation tomorrow.

Simple green has a aircraft one for aluminum,,,,, I did it a few times...it got better but you really need to pull the rad and air to air to clean them up...

You've gotta watch using power washers on radiators. If you get them too close you can close up the fins and ruin the radiator. Please don't ask how I know this.

Gotta select the right tip and keep some distance.
If you do bend radiator fins, there is a comb you can buy at NAPA to straighten them.

I got a soap dispenser for a power washer. Without the soap container, it also acts as a very short power washer gun. Good for underbody / engine / radiator use.
You just have to be very careful you have a good grip and aren't pointing at any body parts before squeezing the trigger.
