Follow these steps for a smooth, perfect finish and avoid common mistakes. Whether you're a beginner or seasoned player, this guide will ensure your walnut is ready for optimal patina development.

The Principle and Importance of Walnut Prepping

What Standard Should You Reach Before You Start Playing with Walnuts?

This is a common question many new walnut players are confused about. The basic standard for preparing your walnut is to ensure that the gaps are free of any flesh residue, and that there's no white alkali residue attached to the surface. The surface and the deep grooves should show light, subtle traces of a ceramic-like coating.

Before explaining why this matters, let’s introduce a key concept—dirty patina. While it’s still a form of patina, dirty patina is mixed with impurities that make the walnut surface look cloudy and murky. Part of the reason for this cloudiness comes from alkali.

So, what is alkali? It’s a water-soluble inorganic salt that comes from within the walnut. Visually, it appears as white powder or blocky deposits on the walnut surface. After the walnut’s green skin is removed, it undergoes a natural drying process. The internal moisture of the walnut evaporates through small pores in the shell, and the dissolved salts are carried to the surface with the moisture. As the moisture evaporates into the air, the dissolved salts lose their solvent and settle on the surface in a solid, white form, creating alkali.

If left untreated, sweat from your hands will dissolve these salts, and combined with the accumulation of oils and dust, a dirty patina layer forms. This is clearly not the ideal patina new players are aiming for. Therefore, properly preparing the walnut is one of the key factors in achieving a beautiful and well-maintained patina later on.

How to Determine if Your Walnut Needs Prepping

Do All Walnuts Need Prepping?

The short answer is no, not all walnuts need prepping. Walnut preparation is a highly flexible choice depending on your preferences and experience.

For beginner players, it’s generally recommended to prepare the walnut when you first get it. This reduces the risk of ruining the walnut later on and ensures that it develops a smooth, desirable patina. For high-quality walnuts, prepping is also advised to maximize the potential of the walnut's skin texture.

However, if you choose to prep your walnut, you should be prepared for the process. Preparing walnuts often requires tools like a wire brush, which can leave scratches on the surface if used improperly by beginners. Additionally, if you're prepping your walnut in winter, be cautious of the walnut cracking due to the cold.

For experienced players, whether or not to prep the walnut is a matter of personal choice, based on your experience. If you have practice walnuts or those with already mature skin, you can start playing with them directly without needing to prep. But for the best results, prepping is still an option.

How to Prep Your Walnut: Step by Step

Proper walnut prepping is essential to achieve a smooth, well-maintained patina. In this guide, we'll walk you through two effective methods for prepping your walnut, including the necessary tools and step-by-step processes

Method 1: Walnut Prepping with Steel Wire Brush

Tools Needed:

• Cotton gloves (and disposable transparent gloves for sweaty hands)

• Small toothbrush

• Hard nanobrush

• Soft nanobrush

• Soft steel wire brush

Step-by-Step Process:

1. Prepare the Walnuts and Wear Gloves:
   Start by selecting a pair of unprepped walnuts. Put on your cotton gloves, and if you tend to sweat, wear a layer of disposable transparent gloves inside to prevent sweat from reaching the walnut surface. This is an important step for ensuring a clean, shiny patina later on. Next, hold the walnut firmly in your hand, placing it between your palm and thumb for stability.

2. Clean with the Soft Steel Wire Brush:
   Begin with the soft steel wire brush. There are three main techniques for using it:

   • First Technique: Gently press the brush into the grooves or areas with flesh residue or dirt. Rub it in circular motions to clean the harder-to-reach areas. This process may take about 3-5 minutes, depending on the walnut's cleanliness.

   • Second Technique: Use the wire brush along the walnut’s surface in the direction of the grain to clean it thoroughly. At this point, you may see white dust and debris coming out from the grooves.

   • Third Technique: Use the wire brush to pick at and clean the deeper crevices, ensuring all dirt and residues are removed. By now, the walnut should start to show a slight sheen, but some white dust may still remain in the grooves.

3. Brush Away Dust with Hard Nanobrush or Toothbrush:
   Next, take the hard nanobrush or a small toothbrush and clean off any remaining dust from the surface and deep grooves. Make sure to brush the grooves thoroughly, pressing the bristles into the lines to dislodge any lingering dust. This process usually takes around 10 minutes and will help brighten the walnut’s surface.

4. Polish with Soft Nanobrush:
   Finally, take the soft nanobrush and use it to polish the walnut. Apply gentle pressure and polish each side for a bit longer to achieve a smooth, slightly glossy finish. This step will give the walnut its first "ceramic-like" glaze.

Method 2: Walnut Prepping with a Bench Vice and Brushes

Tools Needed:

• Walnut holder (bench vice)

• Pig bristle brush (with sanding particles)

• Hard nanobrush

• Soft nanobrush

• Pineapple-patterned nanogloves

Step-by-Step Process:

1. Prepare the Walnuts and Secure Them in the Bench Vice:
   Start with a pair of unprepped walnuts. Use the walnut holder (bench vice) to securely fasten the walnuts in place, ensuring they are stable and won't move during the prepping process. Select a pig bristle brush with sanding particles and use it to gently brush the entire surface of the walnut. The pig bristle brush won't damage the walnut surface and allows you to apply more pressure. This brush works by using the friction of the sanding particles to gradually remove the white alkali deposits. This process should take around 10 minutes.

2. Brush the Grooves with the Pig Bristle Brush:
   Next, press the bristles deep into the walnut's grooves. Rotate the brush in circular motions, both clockwise and counterclockwise, about 300 times each direction. This will ensure the deeper parts of the walnut are thoroughly cleaned. Afterward, give the entire walnut another brushing to ensure all surfaces are clean.

3. Clean the Surface and Grooves with the Hard Nanobrush:
   Use the hard nanobrush to remove any remaining dust from the walnut's surface and grooves. Focus on brushing the grooves deeply, pushing the bristles into the lines to dislodge any remaining residue. This step should take about 10 minutes and will help brighten the walnut's appearance.

4. Polish with the Soft Nanobrush:
   Finally, take the soft nanobrush to polish the walnut. Gently apply pressure while polishing each surface for a bit longer to achieve an even, smooth shine. This will give the walnut its first "ceramic-like" glaze, helping to develop the early stages of the patina. Once polishing is complete, wear the pineapple-patterned nanogloves and gently rub the walnut to enhance the smoothness and sheen.

Core Walnut Prepping Mistakes to Avoid

When prepping your walnut for a beautiful patina, it's crucial to avoid common mistakes that can damage the walnut's surface or hinder the patina development. Here are the key pitfalls to watch out for:

1. Avoid Rushing the Process
   Prepping a walnut takes time. On average, the process should take at least 1-2 weeks, and for walnuts with harder skins, it may take up to a month. If you rush and start handling the walnut too soon, the sweat and oils from your hands can mix with impurities on the surface, causing the patina to darken and develop unsightly spots.

2. Don’t Over-Clean
   Repeatedly soaking the walnut in water or using harsh chemical cleaners can strip away the walnut's natural oils, leading to a dry, cracked surface. This damages the walnut’s texture, making it lose its smooth, warm feel.

3. Avoid Scrubbing Too Hard
   Using a stiff brush with too much force can scratch the walnut’s surface and texture. Once damaged, these scratches are difficult to fix, and the walnut might develop visible white spots or uneven textures, which cannot be easily repaired during subsequent handling.

4. Beware of Improper Environment
   During the prepping process, it’s important to keep the walnut away from humid, sun-exposed, or high-temperature environments (such as near heaters or inside a car). Excessive heat or moisture can cause cracks or deformities. Let the walnut dry naturally in a cool, shaded place without using fans or direct airflow, as this could also lead to cracking.

How to Judge if Your Walnut Prepping is Successful

1. Look:
The surface of the walnut should be even in color, free of visible dust or stains. The texture and grooves should be clear and glossy, without any dark or patchy spots.

2. Touch:
When you touch the walnut, it should feel smooth and refined, with no graininess or roughness. It should rotate smoothly without any sticky resistance, and the surface should have a natural "ceramic-like" feel.

3. Smell:
There should be no unpleasant odor. Only the subtle, natural scent of wood should remain, with no trace of chemical cleaners or mixed sweat odors.

Final Thoughts

Prepping a walnut is like polishing jade before carving—it may seem tedious, but it’s an essential process of “harmonizing” with the walnut. Patience in prepping not only ensures a cleaner and more transparent patina in the future but also allows you to experience the calming beauty of traditional craftsmanship in a slower, more mindful process. With the right tools, such as a Wenwan Care Brush Set, this preparation becomes a refined art, enhancing both the walnut’s surface and your experience. As the walnut becomes warmer and its sheen more subtle, you’ll understand: A great patina always begins with a solid prep, and true craftsmanship comes from devoted care and patience.
