Cleaning Tips

Hot Tanks
Most ferrous (iron or steel) parts may be cleaned in a hot soak tank, but never aluminum or zinc parts. Carburetors, fuel pumps and cam bearing should likewise never be put in a hot tank. Goodson's D-CI25 Cast Iron Cleaning Detergent is a strong, alkaline that removes dirt, heavy oil and grease, carbon, light rust and paint.

Remember that hot tanks are designed primarily to remove organic and rust soils, and it helps to steam clean parts ahead of time to remove most of the grease and oil. Pre-cleaning parts really extends the life of the tank chemicals and reduces soil buildup at the bottom of the tank.

Also, be sure to steam clean or rinse the parts immediately after your remove them from the tanks. If parts aren't rinsed off right away, a thin film will dry on their surface. Once this film dries, it is very tough to remove.

Jet Washers
Jet washers are cheaper to operate than hot soak tanks, and it usually takes less time to clean parts (reduces time to about 10 minutes per block). And, since the parts are sprayed rather than soaked, no area of the part can escape being cleaned. Use Goodson's D-AL50 Aluminum Cleaning Detergent for cleaning aluminum and other non-ferrous parts. It's also safe for plastic and rubber parts.

Testing Hot Tank Solution Strength
We recommend using our PH Checker to test the chemical strength of your hot soak tank or hot spray machine. Compared to litmus paper and other methods of checking acidity, the PH Checker is easier to use and more accurate. It features a large digital display that is easy to read and calibration is simple.

Remember, cleaning depends on the chemical's ability to act as a wetting agent and form micelles. The table below shows you the Basic Concentration Levels to keep in mind when using detergents.

If your solution strength is weak, you can add more chemicals to restore it. If you have any trouble with solution foaming, add D-FOAM Defoaming Agent from Goodson. Start out with 1 oz. per 50 gallons and go from there. You should check the strength of your hot tank frequently, because the chemical will evaporate from a solution quite rapidly due to the heat. And, as always, remember to wear proper safety gear.
