Glass milk bottles are growing in popularity across UK offices, and for good reason. They’re eco-friendly, reusable, and maintain the freshness of milk far better than plastic cartons. If your team values sustainability and a cleaner office environment, making the switch to glass milk bottles is a smart move.
But with this shift comes responsibility. Properly sanitising and reusing glass bottles is essential to ensure hygiene, safety, and long-term practicality. This guide walks you through the best practices for handling reusable glass milk bottles in a professional workplace setting.
Why Your Office Should Embrace Glass Milk Bottles
Glass bottles offer more than just environmental benefits. They help preserve the taste and quality of milk, stay colder for longer, and reduce exposure to chemicals often found in plastic packaging. Offices using glass bottles also tend to reduce waste and promote a greener brand image.
At Office Groceries, we support sustainable practices through our glass milk delivery service, providing businesses with a seamless way to enjoy fresh milk while reducing single-use plastics.
Rinsing Right After Use is Key
Leaving an empty milk bottle on a counter or fridge shelf might seem harmless, but milk residue can sour quickly. Rinsing the bottle immediately after use prevents build-up and makes full cleaning much easier. It also helps eliminate odours and bacteria before they get a chance to take hold.
Encourage team members to give the bottle a quick rinse as soon as it’s empty, a small but essential office habit.
Thorough Cleaning for Safe Reuse
Once a bottle has been rinsed, it needs a proper wash before it’s ready to be refilled or returned. This can be done manually with hot water and dish soap, using a long-handled bottle brush to scrub the interior. Pay close attention to the bottle’s neck and rim, as these areas are common spots for lingering residue.
If your office has a dishwasher, place bottles upside down on the top rack and run them on the hottest cycle available. This will sanitise the bottles while saving time.
Sanitising Methods That Work
Even a clean-looking bottle may still contain harmful bacteria. Sanitising is a crucial step in the reuse process, especially in a shared office kitchen.
You can sanitise bottles in a few simple ways:
- Fill them with freshly boiled water and leave to sit for a few minutes.
- Use food-safe sterilising tablets (often used for baby bottles), following the manufacturer’s instructions.
Once sanitised, rinse the bottle again with clean water and allow it to dry fully.
Air-Drying – The Hygienic Finish
After washing and sanitising, bottles should be air-dried upside down on a clean drying rack. This allows any water to drain fully and avoids contamination from tea towels or cloths, which may introduce lint or bacteria.
Make sure the drying area is well-ventilated and free from clutter. Bottles should only be stored or reused when completely dry to prevent the growth of mould.
Don’t Overlook Bottle Condition
Reusing glass bottles is only safe if the bottle is in good condition.
Always inspect for signs of wear and tear, including:
- Chipped glass, especially around the rim
- Cracks running through the sides
- Cloudy or stained interior surfaces
Damaged bottles should be removed from circulation immediately, as they can pose both a safety and hygiene risk.
Set Up an Internal Return Process
Offices using glass milk bottles should establish a straightforward return routine. Provide a clearly marked collection crate or tray near your kitchen area for used bottles. Staff should be encouraged to place rinsed bottles here, making collection or reuse easy and organised.
This system also helps you track how many bottles are being used, reused, or need replacing, which is particularly useful for sustainability reporting or stock management.

Supporting a More Sustainable Workplace
Adopting glass milk bottles may seem like a small change, but it contributes to a larger culture of sustainability in your workplace. Alongside reducing waste, it encourages mindful consumption, promotes hygienic habits, and builds environmental responsibility into everyday routines.
Combining this switch with other green office initiatives, like fruit delivery, or ethically sourced coffee, can help your office take meaningful steps toward a more sustainable future.
Hygiene and sustainability go hand in hand when it comes to glass milk bottles. With the right care, or the right provider, your office can confidently reuse bottles without compromising on cleanliness or convenience.
