Our multi-step cleaning process restores used IBC totes to food-grade or chemical-grade standards. Every tote is pressure-tested, inspected, and documented. We handle everything from light rinse jobs to full hazmat decontamination.
A garden hose and some dish soap is not IBC cleaning — it is rinsing. Proper reconditioning requires controlled temperatures, specific chemistry, validated contact times, and testing to confirm the job is done. Cross-contamination from a poorly cleaned tote can ruin an entire production batch, trigger a product recall, or create a safety hazard.
Our cleaning process was developed in partnership with chemical engineers and food safety consultants. Every step is documented, every chemical concentration is measured, and every tote is individually tested before release. We do not guess — we verify.
Professional cleaning also extends tote service life. Residual chemicals left in the bottle accelerate HDPE degradation through environmental stress cracking. A properly cleaned tote can serve three to five additional fill cycles compared to one that is simply rinsed between uses.
Each step is performed in sequence with quality checks between stages. Totes that fail any checkpoint are re-processed or routed to recycling.
The tote is positioned over a containment basin and the bottom valve is opened to drain all residual contents. Liquids are captured, identified, and routed to appropriate disposal or recycling. For hazmat residuals, our containment system meets EPA 40 CFR 264 secondary containment requirements. The tote is then inverted briefly to drain the fill port area and any liquid trapped in the valve body.
The bottle interior is flushed with cold water at 40 PSI through a rotating spray head inserted through the top fill port. This initial rinse removes 85–90% of residual product from the walls and bottom. Rinse water is captured and tested — if contaminants are below discharge thresholds, it enters our water treatment system. If above, it is containerized for licensed disposal.
A 160°F alkaline cleaning solution (sodium hydroxide-based, concentration adjusted per contaminant type) is circulated through the bottle for 15 to 30 minutes via a closed-loop spray system. The elevated temperature and alkalinity break down organic residues, oils, surfactants, and most chemical films. For food-grade reconditioning, we use FDA-approved cleaning agents at concentrations specified in 21 CFR 178.
Totes that held mineral-rich products (fertilizers, hard-water chemicals, concrete additives) receive an acid rinse to dissolve mineral scale and calcium deposits. We use a dilute phosphoric acid solution that neutralizes alkaline residue from the previous wash step and removes inorganic buildup that hot wash alone cannot address.
For food-grade and pharmaceutical applications, the bottle is sanitized with a peracetic acid solution — an EPA-registered sanitizer that breaks down to water, oxygen, and acetic acid with no toxic residuals. The sanitizer is circulated for 10 minutes at a minimum of 150 PPM concentration, then drained. No rinse is required after peracetic acid treatment, per FDA guidance.
A final potable water rinse at ambient temperature flushes any remaining cleaning chemistry. The tote is then drained and allowed to air-dry inverted with the valve open. For rush orders, we use forced warm air to accelerate drying to under 2 hours. The fill port and valve are left open during drying to prevent moisture entrapment.
The cleaned tote undergoes visual inspection under high-intensity LED lighting — we check for remaining stains, odors, cracks, wall thinning, and UV degradation. The bottle is then pressure-tested at 2.5 PSI (above the standard UN/DOT test pressure for IBC packaging) and held for 5 minutes. Any tote that fails pressure testing or shows structural compromise is routed to recycling.
Worn or damaged valves are replaced with new 2-inch butterfly valves or cam-lock fittings depending on customer specification. Gaskets are always replaced with new EPDM or Viton seals. The top cap and gasket are replaced if worn. The cage is inspected for bent bars or broken welds, and the pallet is checked for structural integrity. The tote is reassembled, labeled with our reconditioning stamp and date, and staged for pickup or delivery.
Choose the service level that matches your application. Not sure which you need? We assess every tote on intake and recommend the appropriate protocol.
Hot alkaline wash, rinse, inspection, and pressure test. Suitable for non-food industrial applications — chemical storage, agricultural products, industrial fluids, and general bulk storage.
Full wash cycle plus peracetic acid sanitization and FDA-compliant documentation. For totes entering food, beverage, pharmaceutical, or cosmetics supply chains. Includes certificate of cleaning with lot traceability.
Specialized cleaning protocol for totes that held pesticides, solvents, acids, bases, or other hazardous materials. Includes neutralization, multi-stage wash, residual testing, and disposal documentation. Reclassifies the tote from hazmat to non-hazmat status.
Exterior cage cleaning, rust treatment, label removal, and optional repainting. Does not include interior bottle cleaning — often paired with Standard or Food-Grade Clean for full reconditioning.
Every reconditioned tote leaves our facility with a cleaning certificate that documents the date of service, cleaning protocol used, chemicals applied, test results, and the technician who signed off. For food-grade cleans, the certificate includes lot numbers for all cleaning agents and sanitizers used.
Our rejection rate runs about 8% — meaning roughly 1 in 12 totes that come through our cleaning line get diverted to recycling because they cannot meet our quality standards after processing. We would rather recycle a tote than release one that does not pass. That policy protects your product and our reputation.
If a tote we cleaned fails to meet its specified purpose, we replace it at no charge. We have never had to honor that guarantee, but it exists because we stand behind our work without reservation.
Standard cleaning turnaround is 3 to 5 business days from the time totes arrive at our facility. Food-grade work runs 5 to 7 days due to the additional sanitization and documentation steps. Hazmat decontamination takes 7 to 10 days depending on the contaminant and required testing.
For businesses with regular cleaning needs, we offer standing service agreements with reserved processing capacity and guaranteed turnaround windows. These agreements also include priority scheduling during our peak season (spring and fall, when agricultural and chemical clients ramp up tote circulation).
We pick up dirty totes and deliver clean ones using our own transport fleet. Same-day pickup is available in the Minneapolis metro for loads of 4 or more totes. If you are purchasing reconditioned totes, cleaning is already included in the price — you receive them ready to fill.
Different contaminants require different chemistry. A tote that held corn syrup needs a completely different cleaning approach than one that held epoxy resin or hydrochloric acid. Using the wrong cleaning agent wastes time, water, and money — or worse, creates a dangerous chemical reaction. Our cleaning protocols are matched to contaminant type based on the product SDS and our extensive experience with hundreds of different IBC contents.
All cleaning agents we use are commercially available, EPA-compliant, and documented on the cleaning certificate. For food-grade applications, every chemical is FDA-approved under 21 CFR 178 and listed in the NSF International registry of approved cleaners. We do not use proprietary mystery chemicals — you will know exactly what went into your tote and at what concentration.
Our cleaning team includes a certified hazmat technician who reviews every incoming tote's SDS data and prescribes the cleaning protocol. If a tote held an unusual or highly specialized chemical, we consult with the product manufacturer to confirm the safest and most effective cleaning approach before proceeding.

IBC cleaning is water-intensive — each tote requires 40 to 80 gallons of water across all wash and rinse cycles. At our throughput volume, that adds up quickly. Rather than sending thousands of gallons of wash water down the municipal drain, we operate a closed-loop water treatment system that reclaims and reuses approximately 70% of our process water.
Our treatment system uses a three-stage process: oil-water separation to remove floating hydrocarbons, flocculation and settling to capture suspended solids and dissolved metals, and pH adjustment to bring the effluent to neutral (6.5–8.5 pH). Treated water that meets our internal quality thresholds — which are stricter than MCES (Metropolitan Council Environmental Services) discharge limits — is recycled back into the initial cold rinse stage of our cleaning process.
Water that does not meet recycle quality standards is discharged to the municipal sanitary sewer under our industrial pretreatment permit. We test discharge water weekly for pH, total suspended solids (TSS), biological oxygen demand (BOD), and heavy metals. Test results are reported to MCES quarterly and are available for customer review upon request.
Wash water from hazmat tote cleaning is never recycled — it is captured in separate containment, tested, manifested, and disposed of through licensed hazardous waste haulers per RCRA requirements. We maintain a strict segregation between our hazmat and non-hazmat water streams with separate plumbing, containment, and testing protocols.
Five real scenarios from our cleaning operation showing the contamination level, protocol used, and outcome achieved.

We publish turnaround commitments for each service level and we stand behind them. If we miss our guaranteed turnaround window, you receive a 15% discount on the cleaning charge for that batch — no paperwork, no dispute, automatically applied to your invoice. This guarantee reflects our confidence in our process and our respect for your production schedule.
Turnaround is measured from the time totes arrive at our facility (or the time we complete pickup, if using our transport service) to the time they are cleaned, tested, documented, and staged for return delivery or pickup. The clock includes all processing, drying, inspection, and certificate generation — not just the wash cycle.
Rush service is available for all cleaning levels at a 30% surcharge. Rush turnaround cuts the standard window in half — 1–2 days for standard clean, 2–3 days for food-grade, and 3–5 days for hazmat decontamination. Rush orders are given priority on our cleaning line and processed ahead of standard- timeline jobs.
15% discount automatically applied if we miss the guaranteed window. Rush surcharge is 30% of the standard cleaning fee.
Every cleaned tote leaves our facility with a documentation package that provides full traceability and compliance evidence. The depth of documentation varies by service level — standard cleans receive a basic certificate, while food-grade and hazmat cleans receive comprehensive packages with lab results and regulatory references.
For businesses subject to FDA, USDA, or EPA audits, our documentation provides the paper trail that inspectors expect. We format our certificates to align with cGMP (Current Good Manufacturing Practice) documentation standards, so they integrate seamlessly into your quality management system. Lot numbers, chemical concentrations, contact times, test results, and technician sign-off are all recorded and traceable.
Documentation is delivered as a signed PDF within 24 hours of cleaning completion. Hard copies are available on request. We retain all records for a minimum of 5 years and can provide duplicate copies or verification letters at any time. For recurring clients, we maintain a searchable archive of all cleaning records indexed by date, tote ID, and service type.
Not every tote needs professional cleaning. If you are reusing a tote for the same product, rinsing between fills, or preparing a tote for non-critical storage, you can handle basic cleaning yourself. Here is our recommended 8-step process for customers who want to do it right without professional equipment.
Safety Warning: Do not attempt DIY cleaning on totes that held hazardous materials, strong acids, strong bases, flammable solvents, or any RCRA-listed waste. These require professional decontamination and may expose you to chemical burns, toxic fumes, or fire hazards. If you are unsure whether the previous contents were hazardous, contact us before proceeding.
Open the bottom valve and let the tote drain for at least 30 minutes. Tip the tote slightly (5–10 degrees) toward the valve to drain the low corner. Capture all drained liquid appropriately — do not pour on the ground, into storm drains, or into waterways.
Unscrew the bottom discharge valve assembly by hand or with a large pipe wrench. This exposes the full 2-inch drain opening for more effective rinsing and allows you to clean the valve body separately. Inspect the valve gasket — if it is cracked, compressed flat, or hardened, replace it.
Insert a garden hose through the top fill port and rinse the interior with cold water for 5–10 minutes. Direct the stream at the walls and corners. Let the rinse water drain out the bottom opening. This removes 80% of loose residue. Collect rinse water if the previous contents require it.
Fill the tote with 10–15 gallons of hot water (as hot as your tap produces — ideally 120°F+). Add a commercial food-grade alkaline cleaner per the product label (typically 1–2 oz per gallon). Swirl by gently rocking the tote or use a long-handled brush inserted through the fill port. Let the solution sit for 15–20 minutes.
Use a long-handled bottle brush (available at brewing supply stores) to scrub the interior walls, bottom, and corners you can reach through the fill port. Pay special attention to the bottom corners where residue settles and the area around the drain opening. For fill port threads, use a smaller brush or rag.
Drain the wash solution through the bottom opening. Rinse with clean water and drain again. Repeat the rinse a second time. Two post-wash rinses are the minimum to remove detergent residue. If the rinse water still shows color, suds, or odor on the second pass, rinse a third time.
Flip the tote upside down (or lean it at a steep angle with the drain opening at the lowest point) and let it air dry completely. Leave the fill port open. Drying time varies from 4 hours in warm, dry conditions to 24+ hours in cold or humid weather. Do not cap the tote until it is completely dry — trapped moisture breeds bacteria and mold.
Reinstall the valve with a new gasket (or the old one if it is still pliable). Hand-tighten plus a quarter turn with a wrench. Fill with 5 gallons of water and check for leaks around the valve and cap. Visually inspect the interior through the fill port with a flashlight — look for remaining residue, staining, or odor. If it passes your visual and smell test, the tote is ready for reuse.
