Keystone Multi-Quat Sanitizer 2 L for Food Service
When the lunch rush is running and you've got a health check in the same week, you don't want to babysit a chemical that fades halfway through service. Keystone Multi-Quat is a quaternary ammonium sanitizer that holds a steady kill concentration on food contact surfaces without the harsh chlorine smell that clings to your prep area. This 2 L bottle is what we send to a lot of our Calgary kitchens, and a single case has carried a 40-seat counter operation through a full week of service without a single cross-contamination complaint.
Keystone Sanitizer Liquid Multi-Quat 2 L/4.1 LBS (2/Case): Professional Grade for Canadian Food Service
Keystone Multi-Quat is a quaternary ammonium compound built for daily kitchen work. It sanitizes stainless prep counters, cutting boards, food bins, and three-bay sinks, with a contact time that matches what Canadian health inspectors expect in a standard inspection. The formula rinses clean with no white film on stainless steel or glass, which is the little detail that separates a pass from a headache at the end of the night.
Stocked by ChickenPieces.com at our Calgary distribution hub. Delivered Canada-wide, all 10 provinces and 3 territories, in 2-5 business days.
Industry Insider Tip: Set your three-bay sink to the dilution ratio printed on the label and verify it with a quaternary test strip at the start of every shift. The fastest way to drop a sanitizer below its kill range is a greasy cloth or a board that drags food debris into the water. In a busy service, flip the bucket mid-afternoon and you won't be chasing a failed swab test at the worst possible moment.

Operator's Tip · Amani - Bulk & Wholesale Specialist
"We've got a caterer in the northeast end of the city who runs 300-plate events most summer weekends. They used to juggle three different bottles to keep their prep tables clean, now they keep one case of the Multi-Quat on the shelf and a single bottle gets them through the entire event. The test strips stay in range and the table finish is dry, clean, and ready for the next tray."
For non-food staff, a sanitizer isn't a line item, it's the backstop that decides how your health check goes. Provincial and municipal inspectors in Canada expect a quaternary or chlorine compound on food contact surfaces at the right concentration, and the Multi-Quat keeps that check box easy. A clean, streak-free bench isn't just about appearance, it's about cutting the risk of a spot check that slows your whole pass. You'll find it alongside the rest of our back-of-house essentials in the non food range, so you can keep the whole chemical shelf sorted from one Canadian supplier.
Quality & Specifications
Keystone Multi-Quat is a quaternary ammonium compound in a 2 L / 4.5 lbs bottle, two bottles per case. It's formulated for food contact surface sanitizing with a low-foaming profile that works well in three-bay sinks and spray bottles. The concentrate stores clean and the bottle tucks into a standard chemical rack without taking up half the shelf.
Professional Applications
Sanitizes prep counters, cutting boards, sink racks, front-of-house service trays, and beverage stations. It's also fine for a quick wipe on milk fridge handles and coffee bar counters. This is the standard for a diner or catering crew that keeps sanitizing cloths rotation on the line through a long service.
Storage & Handling
Store in a cool, dry, well-ventilated area away from direct sunlight and off the floor in any chemical closet. The printed shelf life holds well when the cap stays tight, and once opened you don't need to rush through it. Keep it well away from chlorine bleach, because mixing a quat with chlorine at the same station can produce the kind of cloud that sends your staff to the washroom.
Canadian Sourcing
We stock Keystone Multi-Quat at our Calgary distribution centre, so the product you receive is fresh, not sitting in a remote warehouse. We ship to all 10 provinces and 3 territories coast to coast, with 2-5 business day transit. That's the kind of consistency you need when you can't stock a month of chemicals and you're ordering a restock in the middle of a season.

Frequently Asked Questions
How do I mix Keystone Multi-Quat to the right concentration?
Follow the dilution ratio printed on the label. That's the only way to get into the required quaternary range for food contact surfaces. Mix the dose the label calls out into a clean bucket of room temperature water, then verify with a test strip. Don't reuse a bucket that held a degreaser, any soap residue will pull the quat strength down fast.
Do I need test strips to check the concentration?
Yes. Food contact surface sanitizing requires a verified concentration, usually a few hundred ppm for quaternary, depending on your local health unit. A quaternary test strip is cheap, takes a few seconds to read, and it's the difference between a pass and a fail on a spot check. Keep the strip container near the sink, not in a drawer of the office.
Can I use this on stainless steel prep tables?
Yes, it's safe on stainless and it doesn't leave the white chalky film you see with chlorine. Wipe the table down first to remove food debris, apply the solution at the label strength, leave it on for the full contact time, then let it air dry. It's about the cleanest way to finish a stainless pass at the end of a shift.
How often do I change the sanitizer solution during a shift?
At least every two hours in active service, or sooner if you see debris floating in the bucket. The solution picks up contaminants from each wet cloth, so it loses headroom without any smell change. Swap it at the start of a shift and again mid-afternoon, and it'll handle a full dinner rush without you worrying about a dirty reservoir.
Is this safe for food prep surfaces?
It's made for food contact surface sanitizing, but it's not for applying to food itself. You let the solution dwell for the time on the label, allow it to air dry or wipe with a clean dry cloth, and the surface is good for food work. Keep the concentrate and any mixed solution separate from open food and from shelves holding dry goods.
What's the difference between this quat and chlorine bleach?
Quat has no strong smell, stays stable in solution longer, and won't bleach out a stainless surface or your towels. Chlorine loses strength fast once mixed and leaves that sharper odour hanging in the back. The one quat trade off is a longer contact time, so just follow the dwell time on the label and you'll get the same result.
Can I use this in a spray bottle for the front of the house?
Yes, it works well in a spray bottle for high-touch spots like menu stands, cashier stations, and milk fridge handles. Mix it at the same food-contact concentration, and use a bottle you've clearly labelled so no one confuses it with a window cleaner. It leaves a clean finish and doesn't leave a chemical smell in the dining area.
How long does the bottle last once opened?
With the cap on tight and stored away from sunlight, the concentrate holds its full performance well beyond the date printed on the label for unopened product. For most kitchens a 2 L bottle runs slow because you're using a low dose per batch. Keep it out of a hot chemical closet and it'll stay reliable across several weeks of daily use.
Does this meet a Canadian health inspection standard?
Yes, it's a quaternary ammonium compound designed for food contact surface sanitizing, which is what inspectors in Canada look for. The key is hitting the concentration on the label, which gets you into the required ppm range. Follow the dilution and dwell time, and you'll walk through the inspection without a chemical-related flag.
