In one paragraph
Every container is drained and classified by prior-product family, then routed to one of three programmes: a three-stage ambient rinse for benign water-miscible residues, a hot-detergent cycle for oils and fats, or a hot caustic clean-in-place at 160–180°F with a 360° rotating lance for the stubborn and the polymerising. Everything that comes out of a bay is leak-tested at pressure, re-valved, re-gasketed and re-marked. Containers that fail a wash twice are rebottled or granulated — never re-graded upward to clear them.
Pre-drain and residue classification
Heel is drained to one of four segregated tanks — aqueous neutral, aqueous caustic-compatible, oil/fat, and quarantine. Classification comes from the signed prior-contents declaration, confirmed on the sniff bench. Anything that cannot be classified goes to quarantine and the unit is routed to rebottling or scrap.
Stage 1 — ambient flood rinse
70–90 gallons of recirculated process water through a fixed spray ball at 45 psi for 90 seconds, drained to coarse settling. This alone clears the majority of water-miscible residues: liquid fertiliser, glycols, surfactant dilutions, most food concentrates.
Stage 2 — hot detergent, 140°F
Alkaline detergent at 1.5–2.5% through the rotating lance for 3 minutes at 160 psi. This is the programme for oils, fats, waxes and anything that films. Temperature matters more than pressure here; below about 130°F animal fats simply re-deposit on cooling.
Stage 3 — hot caustic clean-in-place, 160–180°F
Sodium hydroxide at 2–4% with a surfactant package, 360° rotating lance, 6–9 minutes depending on prior-product family, followed by two fresh-water rinses and a pH verification on the final rinse. Reserved for pigments, resins, adhesives, heavy agricultural concentrates and anything that has begun to plasticise into the bottle wall.
Dry, inspect, backlight
Forced-air dry, then a second backlight inspection looking for ghosting, crazing, stress whitening at the lower radius and any residual haze. A unit that still ghosts after Stage 3 is not washed again — it is rebottled or granulated.
Leak and pressure test
Air test to 3 psi held for 5 minutes with a soap-film check on the valve boss, the lid seat and the lower seam; hydrostatic verification on a sampled basis and on 100% of food-line units.
Re-valve, re-gasket, re-lid
New 2" butterfly or ball valve to order, new EPDM or Viton gaskets selected for the customer's product, new lid with a fresh foam or EPDM seal, and a tamper-evident dust cap. The old valve is harvested for parts, never refitted.
Re-mark and photograph
Reconditioner mark applied under 49 CFR 178 with our code and the month and year of reconditioning, grade stencilled on the cage, unit photographed on the rack. The photo set is what travels with the quote.

This matrix is a summary of an internal list covering about 140 named prior products. If yours is not obviously in one of these families, send it on the form and we will tell you which row it lands in — including when the answer is “we will not take it”.
Four things we will not wash
- Unknown mixed residue. Two chemistries we cannot identify in one bottle is a safety problem for the operator on the lance, not a commercial judgement call.
- Acutely hazardous waste residues. RCRA P-list and similar. These belong with a licensed treatment facility, not a container reconditioner.
- Pesticide concentrates outside the labelled rinse programme. If the label prescribes triple-rinse-and-puncture, the container's service life is over by regulation, whatever its condition.
- Anything radiological. No exceptions, no testing, no discussion.
Refusing roughly one inbound load in twelve is a feature of the model. The 2015 entry in our history explains the load that taught us to do it.

The water train
Five stages, and the sludge nobody talks about
A wash cycle moves roughly 90 gallons; fresh make-up is about 31. The difference is the train below.
| Stage | What it removes | Mechanism | Residence / detail |
|---|---|---|---|
| 0 — Pre-drain and segregation | The concentrated heel | Gravity into four classified tanks | By prior-product family |
| 1 — Coarse settling | Solids, fibre, heavy emulsified fraction | Gravity, three baffled chambers | ≈ 40 min combined |
| 2 — Dissolved air flotation | Fine suspended solids and oils | Micro-bubble lift, surface skim | Temperature-sensitive |
| 3 — Cartridge polish and re-dose | Residual fines; restores concentration | 25 µm filtration, pH correction, titrated dosing | Returns to the lance header |
| 4 — Heat recovery | n/a — recovers energy | Plate exchanger off outgoing rinse | 62% recovered, feed ≈ 110°F |

What a finished batch looks like
Uniform clarity across a row is the visible sign of a programme that ran correctly. Where you see variation — a hazier unit beside a clear one — it is almost always a prior-product difference rather than a wash difference, which is why the routing matrix above matters more than the pressure on the lance.
Each of these carries a wash record indexed to its serial: bay, programme, temperature, chemistry concentration, cycle time, final-rinse pH and conductivity, backlight result, leak test outcome, components fitted and marking date.
