Pristine Extra®
for Swimming Pools. Granular Dichlor shock & oxidizer of organic material, odors, oils, etc.

Pristine Extra® quickly dissolves & helps effectively removes swimming pool odors and organic materials (make-up, suntan lotion, bug sprays, etc), contaminants, and body oils that left untreated build up and cause cloudy or dull water. Pristine Extra® is made with pure dichloro and is formulated with a relatively neutral pH (about 6.0) to work perfectly with your PristineBlue® chlorine free system. 

Weekly or biweekly shocking is recommended for all swimming pools.

Helps prepare the pool for Pristine Blue by really getting rid of organic waste or in a spring opening.
