A traditional brush used in everyday Japanese kitchens.
Cooking with cast iron is simple, but cleaning can be a little confusing. Food can stick, using metal scrubbers can damage the surface, and using a sponge on a hot pan can cause it to burn, melt, or release a chemical smell.
That’s where a brush like this becomes useful.
What is a Karukaya brush?
A karukaya brush is made from the roots of a grass plant and shaped into a slim, stick-like scrubber.
Because the fibers are firm but not abrasive, it removes residue without stripping the seasoning too aggressively.
Since it doesn’t absorb oil, it works well for cleaning and doesn’t feel sticky after washing.
It also dries quickly after use, making it clean and easy to handle.
Size and Design
Two sizes are available, both comfortable to hold even for smaller hands.
As the tips wear down or start to feel worn, the wire binding can be removed and the fibers can be trimmed slightly to continue using it.
It also has a loop, so it can be hung to dry — a small detail that keeps it clean.

A few small notes on using it
For cast iron, I mostly just use water and the brush — soap only when I really need it.
One of the biggest advantages is that it can be used while the pan is still hot. Unlike a sponge, it doesn’t burn, melt, change shape, or release strange smells. The stick shape also keeps hands at a safe distance from the heat.
At first, some fibers may come loose, but this settles down over time.
After use, I usually rinse it in warm water, shaking it lightly to release anything caught between the fibers.
