Anyways, oops, sorry I use one pound of citric acid powder to three gallons of distilled water .

ALWAYS MIX OUTSIDE THE ENGINE .

Vinegar work well to clean old rust but it also allows flash rusting as soon as you rinse it off .

For this reason I like to use Phosphoric acid mixed 50/50 with water to de rust things, it leaves a slight Phosphorus coating that retards rusting .

I like looking at your work, I try hard to keep my engines clean but it's hard .
