Flash Rusting After Cleaning

If your products are experiencing flash rusting immediately after being sent through your cleaning process, you should look into three possible causes.

Possible Cause: Low final rinse temperature

Solution: Raise the temperature of the final rinse or add rinse additives and rust-proofing compounds

Possible Cause: Using an improper rust inhibitor

Solution: You may need to evaluate the rust inhibitor you are using to be sure it is the best product for your process

Possible Cause: Contaminated final rinse

Solution: You may need to increase the rinse stage overflow or completely replace the rinse solutions more frequently than you do now
