The Difference Between Sanitizing and Disinfecting in a Louisiana Early Learning Center
Sanitizing lowers germs to a level public health codes consider safe. Disinfecting kills germs on the surface. In a Louisiana daycare, the state Sanitary Code requires disinfecting diaper-changing tables and potty chairs after each use, and toilets and floors daily. Toys children mouth must be washed and sanitized at least daily, and food surfaces follow the food code.
TLDR:
- Sanitizing and disinfecting are different jobs with different products, strengths and contact times.
- Louisiana’s Sanitary Code sets the surface rules. Bulletin 137 adds that cots, cribs and mats are sanitized daily.
- Diaper tables and potty chairs are disinfected after every use. Toilets and hard floors are disinfected daily.
- Mouthed toys are washed and sanitized at least daily. High chair trays need a food-safe sanitizer.
- The state’s disinfecting mix is 1/4 cup of bleach per gallon of water, made fresh every 24 hours.
- Any product you use must carry an EPA registration number and be used as the label directs.
A Louisiana early learning center answers to two rulebooks. The Department of Education’s licensing rules, Bulletin 137, cover the center. The Louisiana Department of Health’s Sanitary Code covers how it is kept clean, and a center needs Office of Public Health approval to get and renew its license.
Neither rulebook uses one product for everything. They sort the building surface by surface. This guide lays out which surfaces get sanitized, which get disinfected, and the bleach strengths written into state code.

Clean, Sanitize, Disinfect: Three Different Jobs
It is easy to treat these three words as one. They describe three different steps, and each one has a job the others cannot do.
The federal childcare standard, Caring for Our Children Basics Standard 3.3.0.1, defines them this way:
- Clean removes germs, dirt, oils and sticky substances with soap or detergent and water.
- Sanitize reduces the number of germs after cleaning, using an appropriate product.
- Disinfect kills remaining germs on surfaces or objects, and the surface must be cleaned first.
The EPA draws the same line. Its page on antimicrobial pesticides says sanitizers reduce microorganisms “to levels considered safe as determined by public health codes or regulations.” Disinfectants “destroy or irreversibly inactivate infectious fungi and bacteria.”
Cleaning always comes first. A sanitizer or disinfectant cannot work through a layer of food, dirt or body fluid, which is why both standards say to clean the surface before you treat it.
Which Louisiana Rulebook Sets the Standard?
Look for sanitizing rules in Bulletin 137 and you will find very little. Most of them live in the health code instead.
Bulletin 137, LAC 28:CLXI, requires that “the cots, cribs and mats shall be sanitized daily” (§1907). It requires cleaning supplies and chemicals to be kept “in a locked cabinet or other secure place.” It does not set a bleach strength or name an EPA product.
Those details are in the Louisiana Sanitary Code, LAC 51 Part XXI, which covers day care centers. The code defines a day care center to include an “early learning center,” so it applies to licensed childcare.
The two connect at licensing. Bulletin 137 §701 lists “Office of Public Health approval” as a condition of the initial license, and §713 requires current OPH approval before renewal. The Louisiana Department of Health’s own day care plan review questionnaire (Rev. 2/2025) asks each center going through plan review which sanitizer or disinfectant it will use.
Surface by Surface: What Gets Sanitized and What Gets Disinfected
Here is where the two rulebooks land on the surfaces that matter most. The Louisiana column is the binding rule. The federal column comes from Caring for Our Children Appendix K and CDC guidance, and adds detail where state code is silent.
| Surface | Louisiana rule | Federal guidance |
|---|---|---|
| Diaper-changing tables | Disinfect after each use (LAC 51:XXI.303.C) | Clean and disinfect after each use; air dry |
| Potty chairs | Clean and disinfect after each use (301.B.6) | Clean and disinfect after each use |
| Toilets and fixtures | Clean and disinfect at least daily (301.B.5) | Clean and disinfect daily |
| Hard floors | Mop with a disinfecting solution daily and when soiled (301.B.3) | Clean and disinfect bathroom floors daily |
| Toys children mouth | Wash and sanitize at least daily (301.B.1) | Sanitize before another child uses it |
| Table tops and washable toys | Clean at least weekly (301.B.1) | Classroom toys cleaned weekly |
| High chair trays and food tables | Food code applies (105.I.1) | Clean and sanitize before and after each use |
| Cots, cribs and mats | Sanitize daily (Bulletin 137 §1907) | Disinfect if soiled with body fluids |
| Body fluid spills | Clean immediately, then disinfect (301.B.7) | Disinfect |
The pattern is simple. Anything that touches diapers, toilets or body fluids gets disinfected. Anything that touches mouths or food gets sanitized with a product that is safe for food contact.
Bleach Strengths: Louisiana’s Ratio vs CDC’s
Bleach is the one product Louisiana’s code names, and the strength matters. Too weak and it does not do the job. Too strong and it leaves residue on surfaces children touch.
The Louisiana code writes its ratio into the rule itself. Changing tables are wiped “with an approved disinfecting solution (e.g., 1/4 cup of liquid chlorine bleach per 1 gallon of water made fresh every 24 hours).” Surfaces soiled by body fluids get the same 1/4 cup per gallon mix.
| Purpose | Mix | Source |
|---|---|---|
| Disinfecting (Louisiana code) | 1/4 cup bleach per 1 gallon water, fresh every 24 hours | LAC 51:XXI.301.B.7 and 303.C |
| Disinfecting (CDC) | 5 tablespoons (1/3 cup) per gallon, wet at least 1 minute | CDC, cleaning with bleach |
| Sanitizing (CDC) | 1 tablespoon per gallon, soak at least 2 minutes, do not rinse | CDC, early care settings |
The state’s 1/4 cup equals 4 tablespoons, slightly under CDC’s disinfecting mix and four times its sanitizing mix. For a Louisiana center, the state ratio is the one in the rule the health inspector reads.
CDC’s guidance on cleaning with bleach notes that most household bleach contains 5% to 9% sodium hypochlorite. That range is why the label matters. A concentrated bleach and a regular bleach do not make the same solution at the same ratio.
Mix bleach into water, not water into bleach, to reduce fumes. Make a fresh batch every day, and label the bottle with what it is and when you mixed it. Both steps come from Caring for Our Children Appendix J.

Food-Contact Surfaces Follow the Food Code
High chair trays, snack tables and kitchen counters sit in a different category. Once a center serves food, the food code governs those surfaces, not the general cleaning rules.
The Sanitary Code says that where seven or more individuals are cared for, food preparation and handling must meet Part XXIII, Louisiana’s retail food code. That part sets chlorine sanitizer strength by water temperature and pH, for example 50 mg/L at 100°F, or at 75°F when the pH is 8 or less. It requires a contact time of at least 10 seconds.
It also requires “a test kit or other device that accurately measures the concentration” of the sanitizing solution. In practice, that means chlorine test strips next to the sink, and staff who know how to read them.
At the top end, federal rule 40 CFR 180.940 caps chlorine sanitizing solutions for food-contact surfaces at 200 ppm of available chlorine. The CDC’s early care and education guidance adds the timing: “Wash, rinse, and sanitize highchair trays just before and right after they are used for eating.”
Reading an EPA Label Before You Buy
Every sanitizer and disinfectant sold in the United States is registered with the EPA as an antimicrobial pesticide. That registration number is your first check on any product.
Federal labeling rules require the registration number on the label, preceded by “EPA Reg. No.” Caring for Our Children Appendix J explains why it matters: “A product with an EPA registration number on the label has been tested and is effective in reducing or killing germs.”
Three things on the label decide how you use it:
- The claim. Sanitizer, disinfectant or both. Some products do both at different strengths or contact times.
- The contact time. Appendix J says to let a disinfectant “sit on the surface and be visibly wet for the number of minutes listed on the product label.”
- Food-contact directions. For toys and high chair trays, choose a product with directions for food-contact surfaces.
Federal rules also require every pesticide label to carry the same warning: using the product “in a manner inconsistent with its labeling” violates federal law. Wiping a disinfectant dry after a few seconds, when the label says ten minutes, is a label violation.
Chemical Storage and Timing Around Children
The safest product still becomes a hazard in the wrong place. Both Louisiana rulebooks address storage directly.
The Sanitary Code requires cleaning materials to stay “in their original labeled containers” and, when not in use, “in a locked place inaccessible to children and stored separately from medications and food.” It also says open containers such as mop buckets “shall not be left unattended.”
Timing matters too. Caring for Our Children Basics says staff “should not use cleaning, sanitizing, or disinfecting products when children are nearby.” Heavier disinfecting work fits best before children arrive or after they leave.
Building a Posted Sanitize-and-Disinfect Schedule
A posted schedule turns the code into a routine staff can follow and inspectors can see. Caring for Our Children Basics recommends that programs “post cleaning schedules” for staff and families.
A workable schedule for a Louisiana center groups tasks by timing:
- After each use: disinfect diaper-changing tables and potty chairs. Sanitize high chair trays and food tables before and after meals.
- Daily: sanitize mouthed toys, and cots, cribs and mats. Disinfect toilets, fixtures and hard floors.
- Weekly: clean table tops and washable toys. Launder sheets at least weekly.
- Immediately: clean and disinfect any surface soiled with urine, feces, vomit or blood.
One more rule belongs on the list. If a child is suspected of having a communicable disease, the Sanitary Code requires that “all equipment used by the child shall be cleaned and sanitized after use.” During illness outbreaks, Caring for Our Children Basics notes that staff may need to sanitize or disinfect more often. Our flu and norovirus cleaning protocol for schools covers outbreak cleanup step by step.
Common Questions About Sanitizing and Disinfecting in Louisiana Daycares
These are the questions early learning center directors ask most when they set up or review a cleaning plan. Each answer points back to the Louisiana rule or federal standard behind it.
What is the difference between a sanitizer and a disinfectant?
A sanitizer reduces germs to a level public health codes consider safe. A disinfectant kills germs on the surface. Sanitizers fit surfaces that touch food or mouths, like toys and high chair trays. Disinfectants fit surfaces tied to diapering, toileting and body fluids, such as changing tables and potty chairs.
What bleach ratio does Louisiana require for daycare disinfecting?
Louisiana’s Sanitary Code gives 1/4 cup of liquid chlorine bleach per 1 gallon of water, made fresh every 24 hours, for changing tables and for surfaces soiled by body fluids. The code allows another approved disinfecting solution in its place. The product’s EPA label directions still apply.
How often do daycare diaper-changing tables need to be disinfected?
After every use. The Louisiana Sanitary Code requires changing tables to be washed to remove visible soil and then wiped with an approved disinfecting solution after each diaper change. Disposable paper liners approved by the health department may be used, but each one is discarded right after the change.
How often must daycare toys be sanitized in Louisiana?
Toys children may put in their mouths must be washed and sanitized at least daily under the Louisiana Sanitary Code. Washable toys and table tops that are handled but not mouthed must be cleaned at least weekly. Soft toys that cannot be washed are limited to personal items from home that are not shared.
Can a daycare use one product for everything?
Sometimes. Some EPA-registered products both sanitize and disinfect, using different concentrations or contact times for each job. The label decides. For toys and food surfaces, the product needs food-contact directions. Using one mix everywhere, at one strength, usually means one set of surfaces is getting the wrong treatment.
Who inspects cleaning at a Louisiana early learning center?
Two agencies are involved. The Louisiana Department of Education licenses the center under Bulletin 137 and requires cots, cribs and mats to be sanitized daily. The Office of Public Health, part of the Louisiana Department of Health, must approve the center for the license and each renewal under the Sanitary Code.
