How to Clean a SCUBAPRO Scuba Regulator
A scuba regulator must lose salt and sand without letting rinse water enter the first stage. SCUBAPRO's post-dive method begins with the high-pressure inlet closed by its protective dust cap and keeps the second-stage purge from being pressed while the unit is unpressurized and submerged. After rinsing, the regulator dries completely in shade and stores with hoses loosely coiled rather than hanging from fittings. This guide covers SCUBAPRO first and second stages, octopus and common hose assemblies. It does not authorize disassembly, internal cleaning or soaking a regulator with an unsealed inlet. Those tasks require special tools and an authorized technician.

Step-by-step instructions
Before you begin: Inspect and prepare
Confirm whether the first stage is yoke or DIN and fit its correct clean, dry closure before water comes near the inlet. Keep the regulator separate from the BCD rinse so a heavy assembly cannot strike the second stage or press its purge. Grit under a mouthpiece, green corrosion, a cracked hose, unusual breathing effort or suspected water entry requires professional inspection. A freshwater soak removes deposits; it does not replace the performance tests and scheduled service needed for life-support equipment.
Step 1: Depressurize and disconnect correctly
Turn off the cylinder, purge pressure while still connected as trained, then remove the first stage. Keep dust and water away from the high-pressure inlet. Do not start rinsing if the dust cap or sealing surface is wet, dirty, cracked or missing.
Step 2: Seal the first-stage inlet
Dry the protective cap and exterior sealing surface without pushing cloth into the inlet, then secure the cap firmly. Confirm the seal covers the opening. A decorative loose cap is not enough. Water entering the first stage can cause corrosion and requires professional attention.
Step 3: Rinse off loose salt and sand
Use gentle fresh water over first stage, second stages, hoses, mouthpieces and swivels. Let water carry debris away rather than scrubbing sand across finishes. Do not aim high pressure into openings, exhaust tees or hose connections.
Step 4: Soak without pressing purge
Place the sealed regulator in clean fresh water for a brief soak consistent with the exact manual. Do not press a second-stage purge button while an unpressurized regulator is underwater; that can let water travel where it should not. Move the assembly gently instead of sharply bending hoses.
Step 5: Remove surface grime carefully
For sunscreen, algae or visible grime on compatible exterior parts, SCUBAPRO's white-regulator care guidance permits mild soap and a soft cloth. Keep soap out of breathing openings and rinse it completely. Do not use bleach, harsh chemicals, solvent or an abrasive pad.
Step 6: Rinse again with clean fresh water
Use a final fresh rinse to remove loosened salt and any soap. Check around the mouthpiece tie, hose protectors and adjustment controls. If water may have entered a low-pressure hose or the first stage, stop and follow SCUBAPRO's service process rather than attempting to dry the inside with household air.
Step 7: Drain and dry in shade
Lift the assembly while supporting the stages and hoses. Towel exterior water and let the regulator dry completely in a dry ventilated place away from heat and direct sunlight. Do not hang the full weight from a hose or use compressed air through a breathing opening.
Step 8: Inspect before storage
Examine hoses for cracks, blistering and stressed fittings; check mouthpieces, the tank-valve O-ring interface and visible filter condition. Controls should move normally. Corrosion, damaged hose, missing mouthpiece tie or suspected water entry needs authorized service.
Step 9: Coil loosely in a dedicated bag
Store only when fully dry. Coil hoses in broad relaxed curves around the stages and place the assembly in a clean regulator bag. Avoid tight contact with darker gear when protecting a white finish. SCUBAPRO recommends regular technician service, with shorter intervals for heavy diving use.
