Does ultrasonic cleaning PCBs turn liquid damage indicators red?

Metin:

Many repair technicians I’ve read recommend thoroughly cleaning PCBs using an ultrasonic cleaner with Branson Ultrasonic Cleaning Solution mixed with water.  It sounds like good advise, except many Apple PCBs have liquid damage indicators. Wouldn’t the water content in the cleaning solution turn them red?
