"What do you do if your blocks get dirty?"
"My baby licked them, is that okay?"
"Can I disinfect them with alcohol?"
If you use wooden building blocks, these questions are bound to come up.
Especially with small children, blocks aren't just for "playing"—they're put in mouths, dropped on the floor, and sometimes touched with food-covered hands.
But don't worry.
With a few simple tips, wooden blocks can be kept clean and used for a long time.
This article will explain everything from how to clean wooden blocks, to disinfecting, mold prevention, and storage methods.
Can building blocks be washed?
In short, "Soaking in water is generally a no-go, but light wiping is fine."
Wood is a natural material, so it tends to absorb water easily.
If left wet for a long time, it can cause:
- Warping
- Cracking
- Deformation
- Mold
Therefore, it's best not to wash them thoroughly with water.
Daily cleaning (basic)
This is enough for daily care.
① Wipe off dust with a dry cloth
If your blocks are just dusty, a light wipe with a dry, soft cloth is all you need.
This also helps preserve the natural texture of the wood.
② If dirt is a concern, use a "firmly wrung-out cloth"
If you're concerned about food stains or grime, it's recommended to gently wipe them with a firmly wrung-out damp cloth.
The key is to avoid making them soaking wet.
After wiping, make sure to dry them thoroughly.
Can I use alcohol disinfectant or alkaline ionized water?
This requires a bit of caution.
Frequent use of alcohol on wooden blocks is not highly recommended.
The reasons are:
- Wood can dry out easily
- The surface can be easily damaged
- The texture of the wood may change
However, in necessary situations, such as during periods of infectious disease, light wiping may be acceptable.
In such cases, the recommended method is:
- Apply a small amount of alcohol to a cloth (do not spray directly)
- Wipe lightly
- Dry thoroughly
* Depending on the coating or finish, discoloration may occur, so if you are concerned, test it in an inconspicuous area.
Also, while "alkaline ionized water" is often considered safe for babies and pets, when untreated wood comes into contact with alkali, the wood fibers can be damaged, leading to discoloration, swelling, and whitening. It is best to avoid cleaning with alkaline ionized water.
* In fact, the blog administrator has already experimented, and the hinoki wood turned yellower than its original color, and the cedar turned blackish, which made me very sad...
Is it okay if my baby licks them?
Babies put everything in their mouths, don't they?
It's actually common for them to "chew" and "lick" blocks.
Many wooden toys are designed with children's use in mind.
However, you should regularly check:
- If the paint and finish are safe
- If it's appropriate for the target age
- If there are any breaks or splinters
Pay particular attention if corners are chipped or the wood starts to crack.
Mold Prevention | Surprisingly Important!
When it comes to wooden toys, humidity is something to watch out for.
During the rainy season and summer, depending on where they are stored, it can lead to mold.
Tips for preventing mold
- Don't seal them too tightly
- Avoid humid places
- Store them dry after playing
- Occasionally take them out of the box and air them out
In particular, never put them in a bag or case while still wet.
How to Store Building Blocks
It's recommended to store them in a well-ventilated place.
For example,
- Cloth bags
- Breathable boxes
- Shelf storage
are recommended.
Conversely, it's safer to avoid:
- Humid places
- Places with strong direct sunlight
- Near water sources
Too much direct sunlight can cause the wood to bleach and change color.
The secret to long-lasting use is not striving for "perfectly clean"
Unlike plastic toys, wooden blocks gradually change their texture.
Small scratches and color changes are, in a way, "proof of play."
As they are used, they can develop a luster, much like leather products.
Instead of trying to keep them perfectly new, it might be just right to maintain a state where they can be used safely for a long time.
By caring for them as you use them, they can be passed down to siblings or kept as cherished memories.
This is a unique charm of wooden toys.
Summary
Caring for wooden blocks is actually very simple.
The basic principle is "dry wiping + light wiping when necessary."
Even this alone is enough to keep them clean.
- Avoid soaking in water
- Use alcohol only when necessary
- Prevent mold with humidity control
- Periodically check their condition
With just a little attention, building blocks can become toys that last a long time.
Please enjoy your favorite blocks for many years to come.
