Southern California's industrial real estate market has a new center of gravity: cold storage. Riverside and San Bernardino counties are seeing some of the largest refrigerated warehouse deals in the country, and the trend shows no sign of slowing. For facility managers running these operations, the shift to temperature-controlled space brings a floor care problem that standard warehouse cleaning practices weren't built to solve.
The Inland Empire's Cold Storage Boom Is Real Money
The numbers behind this trend are hard to ignore. Walmart recently paid roughly $223 million for a 507,000-square-foot cold storage facility in Riverside, a deal reported by GlobeSt and Bisnow that signals just how much confidence major retailers have in the region's refrigerated logistics demand. Around the same time, Southwest Traders paid $40.5 million for an Inland Empire facility and is investing another $25 million to convert a 229,934-square-foot conventional warehouse into a refrigerated distribution center, according to Cold Storage List. Industry analysts point to online grocery delivery, meal kit services, pharmaceutical distribution, and fresh food logistics as the demand drivers, and development costs for cold storage space run $250 to $400 per square foot versus $100 to $150 for conventional warehouse construction.
What that means for facility managers in Los Angeles, Orange County, Riverside, and San Bernardino counties: more of the region's warehouse footprint is moving into temperature ranges between 34°F and well below freezing, and floor care programs designed for ambient-temperature space simply don't hold up there.
Why Cold Storage Floors Are a Different Animal
Cold and freezer environments create problems that don't exist in a standard dry warehouse. Water freezes on contact instead of evaporating, which turns routine mopping or scrubbing into a slip hazard if it isn't managed correctly. Standard rubber squeegees, hoses, and seals crack and lose flexibility in sustained cold, and battery performance drops sharply: a battery-powered scrubber that runs at full capacity at 70°F may retain only around 60% of that runtime at 40°F, and can fail outright below 25°F, based on industry data on cold storage equipment performance. That's a serious operational risk if your only scrubber goes dead mid-shift in a freezer aisle.
This is one of the reasons more cold storage operators are moving to lithium batteries for their floor equipment. Lithium cells retain a much higher percentage of rated capacity in freezing conditions than flooded or AGM batteries, and they hold up better to the repeated partial-charge cycles that come with multi-shift cold storage operations. The tradeoff: even lithium-powered equipment should be allowed to warm up in the charging area before being run back into deep-freeze zones, since extreme cold still affects run time and component flexibility.
Equipment That's Actually Built for the Job
Matching the machine to the environment matters more in cold storage than almost anywhere else in a facility. For large refrigerated distribution centers, a rider floor scrubber with a cold-rated battery pack can cover more square footage per charge than a walk-behind unit, which matters when you're racing the clock before condensation refreezes. Smaller freezer rooms and tighter aisles are usually better served by a compact walk-behind unit that can maneuver around racking without sacrificing scrubbing pressure. Whatever the footprint, the equipment needs to be rated for the temperature range it's actually going to run in, not just the temperature of the loading dock where it's stored.
Cleaning chemistry matters just as much as the machine. Standard warehouse soaps and degreasers can thicken, freeze, or lose effectiveness at low temperatures, which is why freezer-rated cleaning chemicals formulated to work in sub-freezing conditions are worth the switch for any facility running cold storage or freezer space.
Cleaning a Freezer Without Shutting It Down
Cold storage operators face a problem dry warehouses don't: you usually can't shut down a freezer to clean it without risking product loss. That's why warehouse floor cleaning services built specifically around freezer cleaning without shutdown have become a priority request for cold storage facilities across the Inland Empire. The work has to happen in tight windows, with equipment and crews that are already prepped for the temperature, rather than improvised on the spot.
Keeping Cold Storage Equipment Running
Cold-duty equipment takes a harder beating than standard warehouse machines, and it shows up first in seals, hoses, and battery connections. Facilities running cold storage space should be on a tighter preventive maintenance interval than a typical ambient warehouse, with someone checking those components before they fail mid-shift rather than after. Our on-site service and repair team works on all major brands and can set up a maintenance schedule built around the realities of cold storage duty cycles, not a generic interval that assumes ambient conditions.
With 30+ years servicing cleaning equipment across Los Angeles, Orange County, Riverside, and the Inland Empire, we've watched this cold storage buildout accelerate in real time. If your facility is moving into refrigerated space, or already running one that's fighting frozen floors and dying batteries, it's worth a conversation before the next shift, not after the next slip-and-fall.
