Food Grade Citric Acid for Cleaning Hard Water Scaling

Usually ships in 24 hours.

This is a naturally occurring acid found in all citrus fruits such as lemons, oranges, and grapefruits. Sourced in Thailand.  

You can clean your water ionizer of all scale by doing a vinegar-wash or a citric acid wash.  

Note: Wait to do a vinegar wash until it's about time to change the  filter, otherwise it might taint the internal filters. In other words, when you're finished with the citric acid wash put a new filter in the machine.
