Pre-paint detergent

+++++++

Can anyone recommend a detergent to be used to wash steel weldments prior to painting? These weldments will be washed with high pressure hot water (150 degrees F)to remove weld fume residue, oil, anti-spatter compound, dirt, loose rust, etc...
Ideally, this detergent would provide some short term rust prevention. And, be environmentally friendly.
Thanks

Hello, John. Just as we have brand-name dishwasher detergents, laundry detergents, and hand washing detergents, each containing a combination of ingredients optimized to the specific purpose, there are industrial cleaning solutions formulated to the purpose, taking into consideration the spraying temperature, the substrate metal, and the type of soils, etc.

We list many suppliers in our Chemicals directory who each offer a whole range of such cleaners: Accu-Labs, Atotech, Chemitall Oakite, Coyne Chemical, CTS Surtec, Electrochemical Products, Heatbath, Luster-On and Macdermid are a few.
