Do I have to use DI water with CitriSurf?
No. You may use any type of water you choose for dilution and rinsing. Certain industries have purity concerns and choose to only use DI or another type of purified water. For this reason CitriSurf is produced using DI water. However using tap water has no negative effect on the passivation process. Using purified water for the final rinse bath can help avoid waterspotting issues.
