AquaVantage 815 GD
The precision-cleaning benchmark. When the specification says aerospace, medical or critical, this is the aqueous chemistry the industry qualified first — and kept.
Four AquaVantage grades. Same substrate safety across all of them — the difference is the duty.
Degrease, free rinse, corrosion inhibitor
AquaVantage 815 GD does three jobs in one bath, so a part can come out of the machine ready for the next operation instead of going through three tanks to get there.
Degrease
Lifts oils, coolants, buffing compounds, flux, carbon and handling soils off the part. Released oil separates out for skimming instead of emulsifying into the bath, so the tank lasts.
Data sheet: separates oil effectively for easier skimmingFree rinse
The surfactant and builder package is picked so it goes back into solution in the rinse water and sheets off the part, instead of beading up or drying to a film. That sheeting is what a water-break-free surface is.
It matters because of what comes next. Anything left on the surface is an adhesion defect in the paint, the bond, the plate or the coating, and it will not show up until that stage fails.
Data sheet: free rinsing — permits improved adhesionCorrosion inhibitor
Two different jobs, and it is worth keeping them apart. In the tank: the bath is alkaline, so steel sits in its passive range and holds a stable oxide, and the inhibitor package adsorbs a film on the surface. None of that follows the part out of the bath.
Out of the tank: a trace carries through the rinse and holds off flash rust for a short while — indoors and dry. It is a residual film, not a coating. For anything going on a shelf, follow it with a dedicated rust preventative.
Data sheet: in-process corrosion controlGetting the protection to survive the rinse
This is where most people lose it. A freshly cleaned part is the worst case there is — you have just taken off the oil film that was protecting it, and bare steel sitting wet in aerated water goes off in minutes. Four things decide whether it holds.
Three tanks become one. Less floor space, one bath to dose and monitor, one drum to buy, and no transfer between stages for the part to flash over in. Dose and temperature are on the dosage calculator →
Qualification is the product
Any chemistry can claim to clean. What 815 GD carries is different: four decades of aerospace OEMs writing it into their process specifications — Boeing alkaline cleaning, Airbus approved-cleaner listings, Rolls-Royce and Pratt & Whitney overhaul manuals, Lockheed, Sikorsky, SNECMA. When your customer audits your process, the chemistry line is already answered.
The chemistry earns the paperwork. Mildly alkaline (pH 12 concentrate, inhibited), it cavitates superbly and separates oil instead of emulsifying it — released oils rise to the weir, the bath stays clean, and bath life extends accordingly.
Free-rinsing means what it says. Some cleaning chemistries leave a sticky residue film that clings to the part after rinsing — hard to remove, and a real problem when the next step is coating, bonding or inspection. 815 GD rinses away completely: no film, no coating, a genuinely water-break-free surface that the next process meets clean.
And it protects what it cleans. A built-in corrosion inhibitor provides in-process flash-rust protection — parts hold between cleaning, rinse and the next stage without blooming. For longer holds or storage, step up to a dedicated protective; for the normal flow of a production line, the inhibitor carries it.
Compatibility is its quiet superpower: carbon steel to titanium, aluminium to magnesium — the metal most cleaners ban — plus cadmium, chrome and nickel plating, acrylics, painted surfaces and common polymers. One bath serves mixed-material assemblies that would otherwise need three. The single caution: copper alloys may show minor discolouration.
Its home ground is newly manufactured parts: cutting oils and coolants, drawing and lapping pastes, buffing compounds, fluxes and handling soils — the contamination manufacturing puts on, removed before inspection, coating or assembly. Duration typically 3–10 minutes at 60–66 °C.
Doing MRO and rebuild work — service carbon, baked greases, the soils an operating life bakes on? That is heavier duty than GD is built for: its sibling 815 QR-NF carries the same substrate safety with heavy-duty strength, and it is the better pick. Right tool, same family, same paperwork culture.
Foaming tendency is moderate-to-high: run inside the window, degas after make-up, and keep recirculation returns below the surface.
One drum, four working strengths
| General precision cleaning | 7–30%, typically 10% |
| LOX / breathable oxygen service | 7–12% — per NASA oxygen-service cleaning procedures |
| Metal finishing | 7–25% ahead of plate, anodise and bond |
| Repair & overhaul | 7–30% — the MRO workhorse setting |
Rinse to duty as well: <50 µS ultra-clean · <500 µS precision · heated rinse where the OEM spec requires. Keep parts wet between stages to avoid spotting.
Two siblings, one decision
AquaVantage 815 GD
Cutting oils & coolants · drawing and lapping pastes · buffing compounds · fluxes · general contamination. Precision cleaning of parts as manufacturing made them.
AquaVantage 815 QR-NF
Service carbon · baked greases · tenacious operating soils. Heavy-duty strength, same substrate safety — proven in our 70 °C piston ring-groove work.

Cleaning for LOX and breathable-oxygen systems is the least forgiving specification in industry — hydrocarbon residue in an oxygen circuit is an ignition source. 815 GD is used under NASA procedures for cleaning of systems and equipment for oxygen service, at the dedicated 7–12% dilution, with verification to your specified test method. If you maintain breathing-air, diving, medical-gas or aerospace oxygen hardware, this is the bath.

This is not a single-use chemical
A common misconception treats industrial chemistry like dishwater — used once, tipped out. A defended 815 GD bath works for weeks of production: the oil-splitting formulation sends released oils to the weir instead of into emulsion, filtration removes solids, and in-process corrosion control keeps doing its job cycle after cycle.
Better still, bath condition is measurable. A five-minute titration tells you the working concentration exactly — no guessing, no premature dumping, no under-strength cleaning. Top up to specification and keep running; change out on evidence, not anxiety.
Brulin publishes full aqueous-tank maintenance guidelines — flowchart and step-by-step video — and we set your titration schedule during commissioning.
Concentration check — the actual method
| Kit | Brulin Titration Kit (Prod. No. XTRKIT) |
| Sample | 5 mL of working bath |
| Titrant | 1.0 N HCl · indicator: Bromophenol Blue (2 drops) |
| Concentration % | drops of titrant × 0.81 |
| Alternative | 10 mL sample: mL titrant × 0.42 · burette: to pH 3.8, mL × 1.25 |
Five minutes, a drop counter, and your bath stops being a mystery.
Drum and bath, both looked after
- Store cool, ventilated and sealed, out of direct sunlight — away from foodstuffs, acids and incompatibles
- Non-flammable (flash point none to boiling) — no flammable-store requirement
- Original containers only; label integrity matters for your chemical register
Lid the tank between shifts — holds temperature, limits evaporation, keeps airborne dust out of a precision bath.
Idle periods: a warm, stagnant aqueous bath is a growth medium once its preservative system depletes. Circulate the bath periodically during shutdowns, keep concentration at specification (titrate), and never leave an open tank standing for weeks.
Extended shutdown: drain to sealed, labelled containers — or schedule the changeover for restart day and start clean.
Asked at the tank
815 GD or 815 QR-NF — which one for my work?
Can algae really grow in a cleaning bath?
Prevention: run or circulate the bath periodically even in quiet weeks, keep concentration at specification (the titration check takes five minutes), and lid the tank against airborne spores and dust.
If it happens: do not dose on top of a bloom — drain the bath, clean the tank thoroughly including weir and lines with hot fresh solution, rinse, and refill at specification. Growth is a symptom of an under-maintained bath, and the fix is maintenance, not stronger chemistry.
How do I test the dilution ratio? The titration test, step by step
1. Draw a 5 mL sample of the working bath and let it cool.
2. Add 2 drops of Bromophenol Blue indicator — the sample turns blue.
3. Add 1.0 N HCl titrant one drop at a time, swirling, until the colour changes to yellow.
4. Count the drops used: drops × 0.81 = concentration %.
5. Below target (typically 10%)? Top up with concentrate and re-test. On target? Keep running.
Larger samples improve precision: 10 mL sample → mL of titrant × 0.42; burette method to pH 3.8 → mL × 1.25. Log each result — the trend tells you drag-out rate and predicts top-ups before cleaning fades. We set your titration schedule at commissioning.

Filter bags for this bath
The bag is what keeps the bath working — it takes the soil out before it settles back onto the next load. This is a strong alkaline bath, and that rules the media in and out before micron rating comes into it.
Rated to pH 14. This is what it is for. Start at 25 µm unless something downstream needs finer.
