GT pH Probe Cleaner – Restore Accuracy & Extend Probe Life (250ml, 1L)

A Dirty pH Probe Gives You Wrong Readings — Clean It Properly

Your pH meter is only as accurate as the probe it uses. Nutrient buildup, junction clogs, and dried-out electrodes are the #1 cause of drifting, slow, and inaccurate pH readings in hydroponic systems. GT pH Probe Cleaner is specially formulated to deep-clean your electrode, remove contaminants, restore fast response times, and extend the working life of your probe — protecting one of the most important tools in your grow room.

What GT pH Probe Cleaner Does

• 🔬 Deep-cleans the junction and sensitive bulb — removes nutrient buildup, mineral deposits, and organic matter that cause slow or inaccurate readings
• 🔬 Unclogs the reference junction — prevents the blockages that cause pH drift and sluggish response
• 🔬 Restores electrode integrity — eliminates contaminants that degrade the sensitive glass bulb over time
• 🔬 Brings back fast, reliable readings — a clean probe stabilises quickly and holds accurate readings between samples
• 🔬 Extends probe lifespan — regular cleaning is the single best thing you can do to get more life out of an expensive electrode

How to Clean Your pH Probe

1. Pour enough GT pH Probe Cleaner into a clean container to fully submerge the probe tip
2. Soak the probe for 1–2 hours
3. Gently clean the probe tip and junction with a soft-bristle brush or soft toothbrush
4. Rinse thoroughly with tap water and discard the used cleaning solution
5. Store immediately in GT pH Probe Storage Solution — never plain water
6. Recalibrate using pH Buffer 7 and pH Buffer 4 before your next use

⚠️ Always recalibrate after cleaning. Even a perfectly clean probe needs fresh calibration to give you accurate readings.

Storage

Store GT pH Probe Cleaner in a cool, dark place away from direct sunlight and heat. Keep tightly sealed between uses.

Choose the Right Size

• 250ml — ideal for home growers cleaning one or two probes periodically
• 1L — best value for regular growers, commercial operations, or anyone maintaining multiple meters

Tip: Use GT pH Probe Cleaner alongside GT pH Probe Storage Solution and GT pH Buffer Solutions as part of a complete probe maintenance routine — your readings will thank you.
