A complete care guide for solid wood (muku) flooring: routine cleaning tips, periodic maintenance schedules, and when and how to refinish or repaint to preserve the floor's natural beauty.

About 2 min read

Solid wood flooring is loved for the natural warmth of real wood. Many people imagine that "it must be hard to take care of," but once you grasp the basics it is not difficult. This article explains daily care, periodic maintenance, how to choose a finish, and how to deal with common problems with solid wood floors all in one place.

What is a solid wood floor and why does it need care?

Solid wood flooring is flooring made from natural timber used as it is. Unlike standard engineered (composite) flooring, it allows you to enjoy the changes that come with age, but is also more prone to dirt and scratches. If sebum from the soles of your feet, food spills, dust, and mold are left unattended, they turn into dark stains and marks that become hard to remove, so regular care is important.

What is the daily care routine?

The basis of daily care is dry wiping. Use a dry cloth, rag, or mop to wipe away dust, and when dirt is noticeable, wipe with a tightly wrung damp cloth. Wiping with a soggy cloth can cause the wood to warp or develop mold, so always wring it out firmly. If you use detergent, use only a neutral detergent. Strong acids or alkaline cleaners damage both the finish and the wood.

How should periodic maintenance be done?

When a solid wood floor dries out, splinters and a rough surface texture appear. Carry out oil maintenance (waxing) once or twice a year. It is efficient to combine cleaning, scratch repair, and refinishing at the same time.

Types of finishes for solid wood floors and how to choose

Type of finishCharacteristicsBest suited for
Chemical finish (urethane coating)Forms a film on the surface. Strong against dirt and scratches with a glossy sheenPrioritizing durability / wanting easy maintenance
Natural finish (penetrating oil)Penetrates into the wood. Preserves the natural texture of the woodWanting to enjoy a natural-material feel / households with small children

How to handle common problems

Splinters have appeared

For small ones, blend them in with sandpaper; for larger ones, cut them off at the base with a utility knife and finish with sandpaper. The finish will be removed where you sand, so consider refinishing the spot.

You spilled coffee or soy sauce

Wipe it dry immediately, and if it does not come off, wipe with a tightly wrung damp cloth. If a stain remains, sand it off and refinish. Treating the floor with wax in advance for water repellency helps prevent absorption.

A dent has formed

  1. Apply a small amount of water to the dent and leave it for 30 minutes
  2. Wipe off the water and place a damp towel over the wound
  3. Apply a heated iron over the towel
  4. Repeat while checking the result

The fresher the scratch, the easier it is to repair, so prompt action is the key.

Frequently Asked Questions (FAQ)

Q. Can I use a vacuum cleaner on a solid wood floor?

Yes, you can. However, move it along the wood grain and avoid settings with overly strong suction. Using it together with dry wiping is ideal.

Q. Is waxing necessary on a solid wood floor?

For natural finishes, oil maintenance once or twice a year is recommended. For chemical (urethane) finishes, use the wax specified by the manufacturer.

Q. Are solid wood floors suitable for households with children or pets?

They scratch easily, but they are also easy to repair, which is one of the advantages of a solid wood floor. The reassurance of a natural material and the warmth of wood are also appealing points.

Q. What is the difference between a solid wood floor and engineered flooring?

Solid wood floors are 100% natural wood and let you enjoy the changes over time. Engineered flooring is processed with wood only on the surface; it offers high dimensional stability and is easier to maintain, but the texture is inferior.
