If you are wondering if food grade mineral oil is safe for chopping boards, the short answer is yes: properly certified food grade mineral oil is considered safe for wooden and bamboo cutting boards and is widely recommended by professional kitchens and food safety bodies when used as directed every 3 to 4 weeks.
Why food grade mineral oil is safe for chopping boards
Food grade mineral oil is a highly refined, colourless and odourless oil that meets strict purity standards for contact with food. It does not go rancid like many plant oils, so it won’t leave your board smelling odd after 3 to 6 months of regular use.
On a wooden or bamboo board, such as a Deer & Oak Large Bamboo Board 45x35cm or Large Acacia Board 45x35cm, mineral oil soaks into the fibres and helps to:
- Reduce water absorption by up to 50% compared with an un‑oiled board
- Limit cracking and warping over 5 to 10 years of use
- Make the surface less likely to trap food juices and stains
For most home cooks, re‑oiling a board once every 3 to 4 weeks with food grade mineral oil keeps the board in safe, usable condition for years.
How to use food grade mineral oil on cutting boards
To keep your chopping board safe and hygienic, treat oiling as part of your regular kitchen routine. Here is a simple 6 step method that works for bamboo, acacia and other hardwood boards.
-
Clean the board first
Wash with warm water and a small amount of mild washing up liquid. Rinse and dry with a clean towel, then let it air dry upright for at least 4 hours until fully dry. -
Apply a measured amount of oil
Use about 10 to 15 ml of food grade mineral oil for a medium board around 38x28cm, and 20 ml for a large 45x35cm board. -
Spread in one direction
Use a lint free cloth or paper towel. Work the oil along the grain of the wood in long strokes so it penetrates evenly. -
Let it soak
Leave the board flat for 20 to 30 minutes. Very dry boards, such as a brand new bamboo or acacia board, may need a second coat straight away. -
Wipe off the excess
Buff the surface with a clean cloth until it feels dry to the touch. There should be no oily residue left on the surface. -
Repeat regularly
For daily use, oil every 3 to 4 weeks. For occasional use, every 6 to 8 weeks is usually enough.
Mineral oil vs other oils for kitchen boards
You might be tempted to use whatever oil is already in your cupboard. Some are safe, some are not ideal for long term board care.
-
Food grade mineral oil
Stable, does not go rancid, neutral in taste and smell. Recommended for all Deer & Oak bamboo and acacia boards. -
Specialist board conditioners
Often a mix of mineral oil and natural waxes. These give extra water resistance and a soft sheen on boards such as the Carbonised Bamboo Board. -
Vegetable oils (olive, sunflower, rapeseed)
These can oxidise and turn sticky or rancid in 1 to 3 months, which can affect smell and hygiene. Not recommended. -
Nut oils (walnut, almond)
Sometimes used, but not suitable if anyone in the household has nut allergies. They can also go rancid over time.
For most households, a simple bottle of certified food grade mineral oil is the safest and most practical choice for ongoing chopping board care.
How mineral oil protects different Deer & Oak boards
Deer & Oak boards arrive pre‑oiled and ready to use, but regular top ups with food grade mineral oil will keep them in better condition for longer.
- Moso Bamboo boards such as the Large Bamboo Board 45x35cm and Medium Bamboo Board 38x28cm benefit from light, frequent oiling because bamboo is naturally less porous but can dry out at the edges.
- Carbonised Bamboo such as the Carbonised Bamboo Board 45x35cm has a darker finish. Mineral oil keeps the colour rich and helps resist staining from beetroot, turmeric and tomato.
- Acacia boards such as the Large Acacia Board 45x35cm and Medium Acacia Board 38x28cm have a more open grain. They respond very well to oil, with visible improvement in sheen and water beading after just one treatment.
If you prefer to buy a ready matched set, the Bamboo Double Pack combines a 45x35cm and a 38x28cm board that can both be maintained with the same routine.

Is food grade mineral oil safe for all chopping boards?
Food grade mineral oil is ideal for untreated or pre‑oiled wooden and bamboo boards. It is not needed on plastic, glass or stone boards, which don’t absorb oil and rely on different care methods.
On a thick butcher’s block style board such as the 2.1kg Large Acacia Board, oiling both sides and the edges every month helps prevent cupping and splits. On slimmer bamboo boards in the 1.2kg to 1.9kg range, a lighter coat on the top and edges is usually enough.
Always check that the oil you buy is labelled as food grade or food safe. Non food grade mineral oils, such as some machine or lamp oils, are not suitable for kitchen use.
Who this is for
Ideal for...
- Home cooks using wooden or bamboo chopping boards at least 3 times a week
- People who want their boards to last 5 to 10 years with simple care
- Families who prefer neutral, odourless products that don’t change the taste of food
- Anyone using Deer & Oak boards such as the Bamboo Double Pack or acacia sets and wanting to maintain the factory pre‑oil finish
Not recommended for...
- Households that only use plastic or glass cutting boards
- People who want a completely maintenance free board and never wish to oil it
- Anyone who prefers plant based products only and chooses not to use mineral oil
- Commercial kitchens that are required to follow a specific chemical sanitiser regime without oils
FAQ: is food grade mineral oil safe for chopping boards?
Q: How often should I oil my chopping board with food grade mineral oil?
A: For a board used daily, such as a 45x35cm family board, oiling every 3 to 4 weeks is a good rule of thumb. If the surface starts to look dry or water no longer beads on top, that is a clear sign it needs another coat. Boards used only at weekends can often go 6 to 8 weeks between treatments.
Q: Is food grade mineral oil safe for children’s food and baby snacks?
A: Yes, once wiped and absorbed properly, food grade mineral oil is considered safe for contact with all types of food, including baby snacks and children’s fruit. Always allow at least 20 to 30 minutes for the oil to soak in, then buff the surface until it feels dry before placing food on the board.
Q: Can I use food grade mineral oil on both sides of my cutting board?
A: You should oil both sides and all four edges of wooden and bamboo boards to keep moisture movement balanced. For a heavier board like the 2.1kg Large Acacia Board, treating both faces reduces the risk of warping over time. Apply a slightly thinner coat to the underside if it is rarely used for cutting.
Q: Will food grade mineral oil remove stains or knife marks from my board?
A: Mineral oil will not remove deep stains or knife marks by itself, but it will make light marks less noticeable and help prevent new stains from soaking in. For older boards with heavy staining, a light sanding with fine paper followed by 2 to 3 coats of oil can refresh the surface quite effectively.
