Orenda Technologies ORE-50-148 36/CS 8 oz SPA-500 Pre-Drain System Scrub

The Orenda SPA‑500 is an enzyme‐based pre‑drain scrub specifically formulated for spas and hot tubs. Its potent CV‑600 enzymes work efficiently to break down non‑living organics and oil accumulations that build up in your spa’s plumbing and internal components over time. By eliminating these residues before a drain and refill, the scrub helps ensure cleaner water and a more streamlined maintenance process. This product is NSF/ANSI Certified to Standard 50, highlighting its safety and efficacy for spa applications

How It Works

The product is intended for one‑time use during a deep cleaning cycle. Its concentrated formulation means just an 8‑ounce dose is used per 500 gallons of spa water. The enzyme action rapidly degrades built‑up residues, making them easier to rinse away from the spa shell, jets, and plumbing. The removal of these non‑living organics prevents the recirculation of unwanted particulates when new water is added.

Application Instructions

For best results, follow these step‑by‑step directions:

Step	Action
1. Preparation	Shake the bottle well to evenly distribute the enzymes. Remove the spa filter and clean it separately.
2. Initial Circulation	Turn on the spa/hot tub circulation and jets.
3. Addition	Pour 8 oz of SPA‑500 directly into the spa water (8 oz per 500 gallons).
4. First Cycle	Run the system with all jets/pumps turned on for 5–10 minutes to mix the solution thoroughly.
5. Pause	Turn off the system for 5–10 minutes to allow the enzymes to begin breaking down the deposits.
6. Second Cycle	Turn the system back on for another 5–10 minutes to further circulate and act on the contaminants.
7. Drain & Rinse	Shut off the system and begin draining the water. Rinse the spa shell and run a hose through the skimmer/suction lines to flush out loosened debris.
8. Refill & Balance	Reinstall the cleaned filter, refill with fresh water, and adjust the water chemistry as needed according to your spa manufacturer’s recommendations.

These steps ensure that any buildup inside the spa is effectively removed before the water is replaced, extending the lifespan of the equipment and maintaining optimal water quality.
