Yes, rubberwood is a good material for a cutting board, as long as you treat it like the softer wood it is. It is gentle on knife edges and light enough to move around, but it has little natural resistance to rot, so it has to be washed by hand, dried standing up, and oiled.
Rubberwood comes from the rubber tree, Hevea brasiliensis. According to The Wood Database, the lumber is usually taken from plantations where the trees were tapped for latex, and the trees are cut at the end of their useful life, typically after about 30 years. That is why it shows up in so much kitchen woodenware.
This guide covers how hard rubberwood is compared with maple, walnut, and bamboo, what that means for your knives, how to look after it, and what the evidence says about latex allergy.
| Rubberwood | Hard maple | Black walnut | Bamboo | |
|---|---|---|---|---|
| Janka hardness (lbf) | 960 | 1,450 | 1,010 | 1,410 to 1,610 |
| On your knife edge | Gentle | Firmer | Gentle | Firmer |
| Dishwasher | No | No | No | No |

What Rubberwood Is
Rubberwood is the timber of Hevea brasiliensis, the tree tapped for natural latex. The Wood Database lists it as native to Brazil but widely grown in tropical regions, especially in Asia. Most of it is not exported as lumber. It is made into furniture and household goods first, then shipped, which is why you see it on so many store shelves.
Where the sustainability claim comes from
Brands often describe rubberwood as eco-friendly. The fact behind that claim is that the trees are typically cut after their latex-producing years are over, rather than grown only for timber. The Wood Database also notes the species is not listed under CITES.
Other names you may see
The Wood Database notes rubberwood is sometimes sold as plantation hardwood or Malaysian oak. It is not related to true oak. If a board's label is vague about the species, those names usually mean rubberwood.
How the boards are built
Most rubberwood boards are made from narrow strips glued together side by side, with the long edge of each strip facing up. This is edge-grain construction. The Wood Database says rubberwood glues well. USDA guidance warns that laminated boards may crack and split in the dishwasher, which is one reason glued boards should always be washed by hand.
How Hard Rubberwood Is
The Janka test measures the force needed to press a steel ball halfway into a piece of wood. The Wood Database lists rubberwood at 960 lbf, which puts it close to black walnut at 1,010 lbf and about a third softer than hard maple at 1,450 lbf. Bamboo, which is a grass, comes in at 1,410 to 1,610 lbf depending on which part of the stalk is tested.
What that means for knives
A softer surface gives slightly under the edge instead of pushing back against it. That makes rubberwood a comfortable board for daily chopping, and it is one reason testers such as Wirecutter prize wood for being gentler on knife edges than plastic.
What it means for the board
The trade-off is that a softer board shows knife marks sooner. The Wood Database describes rubberwood's texture as somewhat coarse and open. Expect visible scoring after a few months of use. Light scoring can be sanded out.
Stability
The Wood Database notes that rubberwood tends to warp and twist while it is being dried, but is fairly stable once seasoned. Leaving a board soaking or lying flat on a wet counter is what undoes that.
Rubberwood and Latex Allergy
This is the question we found the least solid information on, and it is worth being plain about that. The Wood Database says people with natural latex or rubber allergies may react to rubberwood. Its guidance is written mainly for woodworkers handling the wood and its dust.
What testing exists
A 2004 Danish Environmental Protection Agency survey of consumer products made from exotic woods examined one rubberwood product and concluded that, with the proviso that only one product was examined, products made of this wood do not seem to present risks for people allergic to natural rubber latex.
What that leaves you with
One product in one survey is thin evidence either way. If you or someone in your home has a latex allergy, ask your doctor or allergist before using a rubberwood board, or choose maple, walnut, or plastic instead.
Is Rubberwood Food Safe?
Rubberwood is widely used for kitchen woodenware, and USDA guidance says consumers may choose either wood or a nonporous surface for cutting boards, including for raw meat and poultry. The wood itself is not the main question. The finish and how you clean it matter more.
Check the finish
In the Danish survey, the only notable chemical emissions from the rubberwood product were traced to its surface treatment, not the wood. For a cutting board, look for one sold as food safe and finished with mineral oil or a board wax, not a lacquer or varnish.
Clean and sanitize it the USDA way
Wash with hot, soapy water after each use, rinse, and air dry or pat dry. To sanitize, USDA suggests 1 tablespoon of unscented liquid chlorine bleach per gallon of water, left to stand for several minutes, then rinsed.
Keep raw meat separate
USDA suggests one board for produce and bread and a separate one for raw meat, poultry, and seafood. A rubberwood board makes a good produce and bread board.
How to Care for a Rubberwood Board
Because rubberwood has very little natural resistance to decay, care matters more than it does for walnut. The routine is simple.
Hand wash, then dry on edge
Wash it by hand, never in the dishwasher, and never leave it soaking. Dry it standing up so air reaches both sides.
Oil it when it is new
Serious Eats recommends saturating a new board with food-safe mineral oil or board cream, letting it absorb, and repeating about three times to cover any thirsty spots.
Re-oil when water stops beading
Sprinkle a few drops of water on the board. If they bead up, the oil is doing its job. If they spread and soak in, apply a thin coat and let it rest overnight. Serious Eats says home cooks can often get away with oiling two to three times a year, more often with heavy use.
What to Look for in a Rubberwood Board
Rubberwood boards vary a lot in quality. These checks separate a good one from a board that will crack or warp.
Tight, even glue lines
Run a finger along the joints. They should be flush and tight with no gaps where water and food can collect.
A food-safe oil finish
Look for mineral oil or a board wax. Avoid boards with a glossy lacquer or varnish on the cutting surface.
At least 3/4 inch thick
Thicker boards resist warping better and have enough weight to sit still on the counter.
The species named on the label
A clear rubberwood or Hevea brasiliensis label is better than vague terms like plantation hardwood.
A size that fits your sink
You will be washing it by hand, so pick a board you can turn and rinse easily.
A plan for raw meat
Pair it with a separate board for raw meat, poultry, and seafood, as USDA suggests.

How Rubberwood Compares
Rubberwood sits in the middle of the wood options. Here is when it makes sense and when another wood suits you better.
Rubberwood board
At 960 lbf on the Janka scale, rubberwood is soft enough to be kind to your knives and light enough to carry to the sink. It needs steady care because it has little natural rot resistance.
Look for
- Tight edge-grain glue lines
- A mineral oil or wax finish
- At least 3/4 inch thick
Watch out for
- Shows knife marks sooner than maple
- Ask a doctor first if you have a latex allergy
Hard maple board
Hard maple is about a third harder than rubberwood at 1,450 lbf, so it resists scoring longer while still being gentle on edges. Wirecutter's top wood pick (updated March 11, 2026) is a maple end-grain board.
Look for
- End grain or thick edge grain
- At least 1 inch thick
- Rubber feet or a flat, stable base
Watch out for
- Heavier to lift and wash
- Still needs regular oiling
Upgrade Your Prep: Get the ROO Bundle
ROO is a silicone mat that sits under your cutting board. It grips smooth countertops so the board never slides, and its built-in 7-cup pouch catches peels and trimmings as you cut. The Bundle includes the mat, a rubberwood board, and a reusable storage bag. $64.99.
Shop the ROO Bundle →Black walnut board
Walnut is almost as soft as rubberwood at 1,010 lbf, so it feels similar under the knife. The Wood Database rates it as very durable against decay, which makes it more forgiving if it occasionally stays damp.
Look for
- Solid or tightly glued strips
- An oil finish
- A size that fits your sink
Watch out for
- Dark wood can hide stains you want to see
- Still hand wash only
Upgrade Your Prep Workflow: The ROO Bundle
A light board like rubberwood is easy to carry to the sink, but that same lightness means it can skid on a smooth counter. The ROO Mat sits under the board and grips the counter so it stays put, and its built-in pouch hangs over the edge to catch up to 7 cups of peels and trimmings while you chop. The ROO Bundle pairs the mat with a rubberwood cutting board that fits it.

Frequently Asked Questions
Is rubberwood good for cutting boards?
Yes. It is a softer hardwood (960 lbf on the Janka scale), so it is gentle on knife edges and light to handle. It needs hand washing, drying on edge, and regular oil because it has very little natural resistance to rot.
Is rubberwood softer than maple?
Yes. The Wood Database lists rubberwood at 960 lbf and hard maple at 1,450 lbf, so rubberwood is about a third softer. It is close to black walnut at 1,010 lbf.
Can people with a latex allergy use a rubberwood cutting board?
The evidence is thin. The Wood Database says people with latex allergies may react to rubberwood, while a 2004 Danish EPA survey of one rubberwood product found no apparent risk. If you have a latex allergy, ask your doctor or allergist first.
Is rubberwood food safe?
USDA guidance allows wood cutting boards, and rubberwood is widely used for kitchen woodenware. Choose a board finished with mineral oil or wax rather than lacquer, and wash and sanitize it as USDA recommends.
Can a rubberwood cutting board go in the dishwasher?
No. Most rubberwood boards are glued from strips, and USDA notes that laminated boards may crack and split in the dishwasher. Wash it by hand and dry it standing up.
How often should I oil a rubberwood board?
Saturate it a few times when it is new, then re-oil whenever water stops beading on the surface. Serious Eats says two to three times a year is often enough for home cooks, more if you use it heavily.
Rubberwood is a sensible everyday board: easy on your knives, light enough to wash, and widely available. Keep it dry, keep it oiled, and keep a separate board for raw meat. If anyone at home has a latex allergy, check with a doctor before you buy.
