Dear Hiring Manager,
I am writing to recommend Rosa Delgado, who worked for me as an evening office cleaner at Marrowby Facility Services for three years. I was Rosa’s operations supervisor during that time.
Rosa cleaned a four-floor office building of about 50,000 square feet on a crew of six. She emptied trash, vacuumed, sanitized restrooms and restocked supplies from a checklist, and she finished her zones on time on nearly every shift. I trusted her with building keys and the alarm code, and she locked up on her own at least three nights a week.
Rosa is honest, careful and on time, and she followed every safety rule. She is ready for a place on any office cleaning team, and I recommend her without hesitation. Feel free to call me with any questions.
Sincerely,
Paul Henderson

Dear Hiring Manager,
I am writing to recommend Jamal Washington, who worked as the daytime office cleaner at Penrose Hollow Property Group for two years. As the office manager, I worked with Jamal every day.
Jamal kept 30 offices, 4 restrooms and 2 kitchens clean while 80 staff members were at work, and he did it quietly and without getting in anyone’s way. He worked well with our reception, maintenance and security teams and covered for a coworker on short notice more than 10 times. Staff often mentioned how fresh and tidy the building looked.
Jamal is friendly, dependable and easy to work with. He is ready for a daytime or team-based cleaning job, and I recommend him with confidence. You are welcome to reach me by phone or email.

Her attendance was among the best on our team of 24.

Dear Hiring Manager,
I am writing to recommend Tonya Mills, who worked for me as an office cleaner at Kettleby Cleaning Solutions for three years. I coordinated her schedule and reviewed her work each week.
Tonya suggested a switch to refillable concentrate, and the change cut our cleaning supply costs by 22 percent in the first year. She also wrote a simple restroom checklist that her crew of seven now uses on every shift. When two coworkers were out, she trained a new cleaner in one week.
Tonya is dependable, positive and always looking for a better way to do the job. She is ready for a team lead role, and I recommend her without reservation. You are welcome to call me.
Sincerely,

Tips for Supervisors and Managers Writing the Letter
- Be specific. Add at least one real example and one number.
- Stay honest. Use facts you have seen, and decline politely if you cannot give a good reference.
- Skip personal details. Leave out age, health, family and religion.
- Mention trust. Say whether the cleaner had keys, alarm codes or access to private offices.
- End clearly. Give a firm recommendation and your contact details.
Cleaning Job Facts From the BLS
| Fact (BLS, janitors and building cleaners) | Figure |
|---|---|
| Median pay (2025) | $36,840 a year ($17.71 an hour) |
| Typical entry-level education | No formal credential |
| Training | Short-term on-the-job training |
| Jobs (2025) | About 2.43 million |
| Job outlook, 2025 to 2035 | Growth of 2% |
| Projected change in jobs | About 53,600 |
| Openings each year, on average | About 321,800 |
The BLS says janitors and building cleaners keep buildings clean, safe and in good condition. Their typical duties include emptying trash, sweeping, mopping or vacuuming floors, cleaning restrooms and stocking them with supplies, and cleaning and disinfecting frequently touched surfaces. The BLS also lists interpersonal skills, physical stamina and time management as important qualities. Use these as ideas for the strengths in the letter. These are national figures, and pay varies by state and employer.
Mistakes to Avoid
- Using vague praise. “Good cleaner” could describe anyone, so add proof.
- Exaggerating. Claims that cannot be checked hurt the cleaner’s credibility.
- Leaving out dates and title. Give the job title and how long the cleaner worked for you.
- Mixing up names. Check the cleaner’s name, your title and your contact details.
- Typos. Proofread twice and ask someone else to read it.

Frequently Asked Questions
What should an office cleaner reference letter include?
Say who you are and how you know the cleaner, give the job title and dates, and describe two or three strengths with examples and numbers. End with a clear recommendation and a way to reach you.
How long should the letter be?
One page, or three short paragraphs. Short and specific letters are easier for hiring managers to read.
Who can write a reference letter for an office cleaner?
A cleaning company supervisor, a facility manager, an office manager or any manager who worked with the cleaner. A client who hired the cleaning company can also write one.
What strengths should the letter mention?
Honesty, reliability, attention to detail, safe use of cleaning products, working without supervision and good manners around office staff. The BLS lists time management, physical stamina and interpersonal skills as important for janitors and building cleaners.
Should the letter include numbers?
Yes. Square feet cleaned, number of offices, on-time rate and inspection scores make the praise believable.
Should I mention trust with keys and alarm codes?
Yes. Office cleaners often work alone at night, so trust with keys, alarm codes and private spaces is one of the strongest points a writer can make.
What is the difference between a reference letter and a recommendation letter?
They are nearly the same. A reference letter confirms the work the person did, and a recommendation letter adds a stronger personal endorsement. The samples here do both.
How do I ask for a reference letter as an office cleaner?
Ask a supervisor or office manager in person or in a short message. Give at least two weeks, share the job you want and suggest a few things you did well.
What if I cannot give a positive reference?
It is better to decline politely than to write a weak letter. You can confirm only the dates and job title instead.
Can I use the same letter for every job?
You can use one for similar jobs. Ask the writer to adjust it when you apply for a different kind of job, such as moving from night shifts to a daytime role or to a team lead role.
Conclusion
A good office cleaner reference letter is short, honest and full of proof. Name the job, add numbers and end with a clear recommendation. Use the samples and builder above to write one today.
