How to Deep Clean an Office: The Ultimate Checklist To Keep Your Office Spotless

Your office is more than just a place to work; it’s where ideas form, connections happen, and productivity grows. But many offices are hiding something less obvious: poor hygiene. In a UK survey of 650 office workers, 28% of telephones, 31% of keyboards, and 36% of computer mice were never cleaned at all. 

That tells us a lot. Even in spaces that look clean, dirt, germs, and allergens can go unnoticed. In this post, we’ll walk you through how to deep clean an office properly, including a checklist, tools, steps, and tips to get your workspace truly spotless and healthier.

Why is Office Deep Cleaning Important?

A deep clean goes further than routine dusting and vacuuming. It tackles hidden dirt, germs, and allergens that build up in desks, carpets, kitchens, and bathrooms. Over time, these can affect air quality and even cause staff illness.

Regular office deep cleaning helps reduce the spread of germs and viruses, lower employee sick days, and keep your workspace organised and productive. It also helps you maintain a professional image for clients and visitors, showing them that your business values cleanliness and care. Deep cleaning keeps your business running smoothly and demonstrates that you care about your team.

How Often Should Offices Be Deep Cleaned?

The frequency of deep cleaning depends on your office size and how busy it gets. Small offices with up to ten people should ideally have a deep clean every four to six months. Medium-sized offices with ten to thirty people should schedule one every three to four months. Larger offices or high-traffic workplaces might benefit from a deep clean every one to two months.

No matter the size of your space, you should still carry out routine cleaning daily or weekly to keep dirt and dust under control between deep cleans.

Daily Office Cleaning

Daily cleaning stops dirt and bacteria from building up and keeps the environment hygienic and easier to maintain. Every day, surfaces like desks, door handles, phones, and light switches should be sanitised to reduce germs. Shared areas such as kitchens and coffee machines should be wiped down regularly to prevent spills and stains.

Bins should be emptied and recycling taken care of daily to prevent bad smells. Toilets should be cleaned and restocked with essentials like paper and soap, while high-traffic floors should be vacuumed or mopped. Doing these tasks every day means that grime does not build up and deep cleans take less time later on.

Weekly Office Cleaning

Weekly office cleaning goes a step further, targeting areas that do not need daily attention but can quickly collect dust and dirt. Each week, spend time vacuuming and wiping down office chairs, soft furnishings, and carpets. Clear out shared fridges and throw away any expired food.

Kitchen appliances such as microwaves and kettles should be wiped clean, and cupboard doors should be dusted. It is also a good idea to clean windowsills, blinds, and doorframes, which can gather more dust than you might expect. Keyboards, mice, and other shared tech should be sanitised, and workstations should be organised for the week ahead. Keeping up with these tasks ensures your office always looks fresh and professional.

Monthly Office Cleaning

Monthly cleaning goes deeper than your weekly routine. This is when you focus on areas that slowly accumulate grime and need extra attention. Take time to clean windows, both inside and outside, and polish mirrors to make them shine. Floors should be polished or carpets shampooed to remove any lingering stains or wear.

Radiators, vents, and light fixtures should be wiped down, as they can easily collect dust that impacts air quality. Communal kitchens and bathrooms should be deep cleaned, including dishwashers and sinks. Cleaning air vents and HVAC systems once a month helps maintain a healthier office environment, improving ventilation and air freshness. Regular monthly cleaning prevents wear and tear, helps maintain air quality, and keeps your workspace feeling like new.

Cleaning Supplies and Equipment Checklist

Before starting any office deep clean, it is important to make sure you have all the right supplies. A deep clean requires more than a few wipes and a bottle of spray. You will need reliable tools such as a vacuum cleaner, mops, and buckets for different floor types. Stock up on microfibre and lint-free cloths for dusting and wiping, as well as disinfectant sprays and all-purpose cleaners for desks and high-touch areas.

You will also need separate bathroom and kitchen cleaners, glass and mirror sprays for a streak-free finish, and gloves to protect your hands while working. Do not forget basics like dustpans, brushes, rubbish bags, and bin liners. If your office has carpets or large floor areas, you might also want to invest in or hire a carpet cleaner or steam cleaner to make sure every area is covered.

Steps

1. Clear Out the Clutter

Start by tidying up desks, shelves, and storage spaces. Remove unnecessary papers, office supplies, and general clutter that has built up over time. Throw away rubbish and recycle old paperwork or materials you no longer need. Clearing surfaces will make it much easier to clean properly later. If you have an office fridge, empty it completely and dispose of any out-of-date food or drink before you begin.

2. Move the Office Furniture

Once everything is tidy, move desks, chairs, and cabinets away from walls. This allows you to reach those hidden corners where dust and dirt often gather. You might be surprised how much grime collects behind large pieces of furniture. Moving items also makes vacuuming and mopping far easier and ensures every part of the office gets attention.

3. Dust and Disinfect

When it comes to dusting, always start from the top and work your way down. Dust light fittings, shelves, and window frames before wiping desks, doors, and walls. Use microfibre cloths and gentle, streak-free cleaning products. Once you have dusted everything, disinfect shared surfaces like keyboards, phones, and door handles.

For electronic devices, use tech-safe cleaning sprays and lint-free cloths to avoid water damage. Kitchens and bathrooms need extra care at this stage. Wipe down appliances, clean sinks and taps, and polish mirrors. Always use separate cloths for bathrooms to avoid spreading bacteria to other areas.

4. Clean the Floor

After dusting and disinfecting, focus on the floors. Start by vacuuming thoroughly, including under desks, chairs, and in corners. If you have carpets, you might want to schedule a professional hot-water extraction to remove deep dirt and bacteria. For hard floors, mop using a suitable cleaner for the surface type, whether it is tile, vinyl, or wood. Use a separate mop for bathrooms to maintain good hygiene.

5. Reorganise

Once all the cleaning is done and surfaces are dry, put everything back in place. Reconnect computers, printers, and other equipment. Restock cleaning products and supplies so they are ready for next time. Finally, do one last walk around to make sure the office is tidy, clean, and ready for use.

What Are the Benefits of Hiring a Professional Office Deep Cleaning Service?

Hiring a professional office cleaning company can make a big difference. It saves you time, guarantees better results, and lets your staff focus on their work instead of worrying about cleaning duties. Professional cleaners use industrial-grade equipment and eco-friendly products to achieve a higher level of cleanliness.

They also work flexibly, often outside office hours, so your workday is not disrupted. Another benefit is compliance, as professional cleaners understand health and safety standards and make sure your workplace meets them. They can also help spot early maintenance issues, saving you from expensive repairs later.
