Cleaning a steel watch: how to do it properly

Stainless steel is one of the most popular and appreciated materials in fine watchmaking for its strength, durability, and timeless elegance. Despite their intrinsic sturdiness, even steel watches require specific care to maintain their shine and ensure a consistently impeccable appearance. Dust, sweat, cream residue, or exposure to particular environmental conditions can, over time, compromise the shine of the case and bracelet.

Understanding how to properly clean a steel watch means not only preserving its aesthetics, but also ensuring its long-term functionality.

Watch Cleaning: Why Does Stainless Steel Require Special Care?

The steel used in watchmaking comes in two main types: 316L and 904L . The former is the most common standard, appreciated for its corrosion resistance and versatility of use. 904L, on the other hand, stands out for its greater resistance to seawater and chemicals, a high brightness and superior surface hardness, which make it less prone to scratches than 316L. Despite these characteristics, both materials can retain residues of dust, humidity and sweat , which over time cause halos and opacity if not removed regularly.

Regular cleaning helps maintain the metal's original shine. Constant care is therefore essential to avoid aesthetic alterations and to preserve the watch's overall integrity, especially when worn daily.

Cleaning a steel watch: how often should you do it?

Determining the correct cleaning frequency depends on the use of the watch and the conditions in which it is worn. In general, a light cleaning with a microfiber cloth can be done after each use to remove sweat and any fingerprints.

A more thorough service , including the case and bracelet links, is recommended every two or three weeks for daily use . If the watch is exposed to more demanding conditions—such as sports, marine environments, or particularly humid climates—it's advisable to proceed more frequently. Professional maintenance , however, should be considered periodically to ensure a complete check of the mechanical as well as aesthetic parts.

How to Clean Steel Watches: Helpful Tools and Methods

Cleaning a steel watch requires the right tools to avoid damaging the surfaces. Some of the most useful tools include:

●       Microfiber cloths : essential for removing dust and fingerprints without scratching;

●       Soft-bristled brushes : ideal for reaching the crevices between the bracelet links;

●       Warm water and neutral soap : a gentle and effective solution for dissolving accumulated dirt.

Before any operation, it is essential to ensure that the watch is waterproof . If not, we recommend avoiding direct contact with water and limiting the external surface to a thorough dry cleaning.

Cleaning steel watches: case and other delicate parts

The case is the most visible part of the watch and the one most likely to attract dirt and fingerprints. Cleaning should be done with gentle movements, using a soft, slightly damp cloth .

Particular attention should be paid to the crown and gaskets , which should never be subjected to excessive pressure to avoid infiltration. In models with a rotating bezel , it is useful to move it during cleaning to eliminate residues that may build up in the sliding mechanism. The bracelet links also require care, as the cracks can trap dust and oily residues that, over time, compromise the shine of the steel.

Cleaning a Steel Watch: How to Treat Surface Scratches

Despite the material's durability, steel watches can suffer from micro-scratches due to daily use. It's important to distinguish between superficial scratches and deeper marks : in the first case, a home repair can improve the appearance, while for more serious damage, it's advisable to contact a specialized workshop . Improper repair could, in fact, compromise the original finish, especially on models that combine polished and satin surfaces.

How to clean a steel watch: glass and cracks

Watch glass , often made of sapphire or mineral, should be cleaned with non-abrasive products to preserve its transparency . Again, using a microfiber cloth is the best solution.

The gaps between the case, buttons, and bracelet are the most critical points, as they easily accumulate dust and dirt. A slightly dampened, soft-bristled brush allows you to reach these areas without damaging them. In more complex cases, using a jet of compressed air can help eliminate stubborn impurities, always taking care not to damage the seals.
