San Diego campuses reopen in late August, and the condition a building is in on day one sets the tone for the entire term. Parents notice. Staff notice. And the surfaces that get missed in the pre-opening push are usually the same ones that drive the first wave of illness in September.
This guide covers what a back-to-school cleaning program should include for schools, preschools, and childcare centers in San Diego, and how to build a schedule that holds up once the year is underway.
Start with a pre-opening deep clean
Summer is the only window in the year when a school building is empty enough for real deep work. Anything that requires furniture moved, floors stripped, or rooms closed has to happen now.
A proper pre-opening scope includes:
- Full classroom reset with desks and furniture moved, floors cleaned underneath, and all surfaces wiped down
- Hard floor stripping, refinishing, and sealing in corridors, cafeterias, and gyms
- Carpet deep extraction in libraries, offices, and carpeted classrooms
- Restroom deep clean including grout, partitions, and fixtures rather than surface wipe-down
- Vent, ledge, and high-surface dusting to clear a summer of settled dust
- Window and glass cleaning inside and out
- Cafeteria and kitchen deep clean ahead of food service inspection
- Locker and cubby cleanout and disinfection
PBS handles floor stripping and waxing and commercial floor care across San Diego County, which for most campuses is the single largest piece of the summer scope.
Classroom standards once term begins
Daily classroom work should focus on the surfaces that transmit illness rather than the ones that look untidy.
Daily: trash removal, desk and table disinfection, door handles and light switches, shared technology including keyboards and tablet carts, pencil sharpeners and supply stations, sink and drinking fountain areas, and floor vacuuming or sweeping.
Weekly: full dusting including shelving and window sills, chair legs and undersides of desks, whiteboard trays, and detailed floor work including edges and corners.
Monthly: vents and high surfaces, wall spot cleaning, baseboards, and a deeper reset of storage and supply areas.
Restrooms drive more complaints than anything else
In every school facility survey, restrooms are the number one source of student and parent complaints, and the number one reason students avoid drinking water during the day. They deserve more than a single daily pass.
For a campus of any size, restrooms need scheduled checks during the school day, not just an end-of-day clean. That means restocking, spot cleaning, and a quick fixture wipe at set intervals. A restroom that is serviced once at 4pm will be in poor condition by 11am the next morning.
Cafeteria and food service areas
Cafeterias combine high traffic, food residue, and health department oversight. Daily requirements include table and bench disinfection between lunch periods where possible, floor scrubbing rather than dry sweeping, trash and recycling management, and serving line surfaces coordinated with kitchen staff.
Grease and food residue on hard floors is also the leading slip hazard on a school campus, which makes cafeteria floor care a safety item, not a cosmetic one.
Gyms and hard floors
Gym floors take the heaviest wear of any surface in a school and are the most expensive to replace. The summer window is when refinishing happens, but the maintenance schedule during the year is what determines how long the finish lasts. Daily dust mopping and prompt spill response do more for a gym floor than an annual refinish alone.
Childcare and preschool: a higher bar
Preschools and daycare centers in San Diego are held to stricter standards than K-12 facilities, and for good reason. Children under five put surfaces and objects in their mouths, and the illness transmission rate is far higher.
A childcare cleaning program should add:
- Daily toy and manipulative sanitization on a documented rotation
- Cot, mat, and nap area disinfection
- Diaper changing station protocols separate from all other cleaning
- Low-surface focus, because everything below three feet is a touch point
- Products selected specifically for safety around young children
PBS provides daycare and preschool cleaning alongside its school cleaning services throughout San Diego County.
Plan for illness season before it arrives
The heaviest absence weeks in a San Diego school year typically fall between late October and February. Build the response into the contract now rather than negotiating it mid-outbreak.
That means agreeing in advance on what an elevated disinfection protocol looks like, which surfaces get additional daily passes, how quickly the provider can add hours, and what triggers the escalation. A provider who can scale up within 24 hours is worth more than one who is slightly cheaper.
Product safety around children
Ask any provider which products they use in classrooms and childcare rooms, whether those products are appropriate for use around children, and how residue is managed on surfaces children touch directly. Strong disinfectants have a place in restrooms and food areas. They are not automatically the right choice for a toddler room floor.
Building a schedule that holds
Most schools do not need more cleaning hours. They need the right hours in the right places. A provider should walk your campus, map traffic patterns, and build a scope that puts daily attention on restrooms, cafeterias, and high-touch classroom surfaces while handling everything else on a defined weekly and monthly cycle.

Frequently Asked Questions
When should a school schedule its deep clean?
Summer is the only practical window for work that requires empty rooms, including floor stripping and refinishing, carpet extraction, and full classroom resets. Most San Diego campuses complete this in July and early August ahead of a late-August start.
What should be cleaned in a classroom every day?
Trash removal, desk and table disinfection, door handles and light switches, shared technology, supply stations, sink and drinking fountain areas, and floors. Weekly and monthly work covers dusting, high surfaces, and detailed floor care.
How is childcare cleaning different from school cleaning?
Childcare adds daily toy and manipulative sanitization, cot and nap area disinfection, diaper station protocols, and a focus on low surfaces, along with products selected for safety around young children.
How often should school restrooms be cleaned?
Once daily is not enough for a campus of any size. Restrooms need scheduled checks during the school day for restocking, spot cleaning, and fixture wipe-downs, plus a full clean at the end of the day.
