Leather Types & Maintenance Guide
1. Aniline Leather (Full grain leather)
Aniline leather refers to leather that retains the complete natural grain layer (the dense fiber structure of the outermost layer of leather), undergoes only slight tanning and dyeing, and has not been polished, embossed, or coated.
Advantages:
1. Natural and Breathable Properties
Aniline leather is made from high-quality embryos of captive castrated bulls, with almost no scars on the surface, retaining intact natural pores and textures. It is not covered by chemical coatings, has excellent breathability, and has a soft and elastic touch.
2. High Durability
Due to the tight fibrous tissue of the skin, with a thickness typically ranging from 1.3-1.6mm, it exhibits excellent tensile and wear resistance, and is not easily deformed after long-term use.
3. Environmental Protection Technology
Adopting direct tanning dyeing to avoid excessive chemical treatment and preserve the natural characteristics of leather to the greatest extent possible.
4. Quality Value
The selection of raw hide materials is strict (high loss rate), the process is complex, and the origin is mainly in Europe /Italy, resulting in a cost price far exceeding that of ordinary leather.
5. Aesthetic Value
Natural textures and scars are considered as "subtle beauty", giving products a unique and primitive texture, often used in high-end furniture.
Process Characteristics:
No artificial modification: Aniline leather is only tanned and dyed on the embryo, refusing deep polishing or chemical covering to preserve the natural state of the cowhide to the greatest extent possible.
Natural trace preservation: The surface allows for slight scars, insect eyes, and other natural imprints, reflecting the "life experience of a cow" without deliberately concealing blemishes34.
Physical Characteristics:
Excellent breathability: Due to the intact pore structure, the breathability is superior to other leather types.
Outstanding durability: The fiber structure is tight, wear-resistant, and has a long service life. During use, it will form a unique "oiliness" and natural patina.
Daily Cleaning: Gentle and gentle, avoid water and chemicals
1. Dust Removal
- Gently wipe along the texture with a microfiber cloth or clean cotton cloth, 1-2 times a week
- Do not use damp cloths or water: Moisture can seep into pores, causing the cortex to harden, swell, or even peel off
2. Minor Stain Treatment
- Oil stains/fingerprints: Use a dry cotton pad or cloth to press and absorb, avoiding spreading after wiping
- Ink/beverage stains: Immediately use a cotton swab dipped in a small amount of specialized leather stain remover to apply (test in an inconspicuous location first), and lightly touch from the periphery to the center of the stain.
Deep Cleaning: Minimalist operation, strict frequency control
1. Step: Only when the dirt is stubborn, use a cotton cloth lightly dipped in warm water (twist until no dripping), gently wipe along the texture in one direction → immediately use a dry cloth to absorb dry → naturally dry in the shade
2. Taboo:
- Prohibit soap, dishwashing detergent, alcohol, etc. (which can damage natural oils and cause cracking)
- Prohibit brushes and sponges (friction damage to the grain surface layer)
Nourishing Care: Less but more refined, simulating natural oils and fats
1. Selection of Nursing Agents
- Must use water-based leather nutrition milk (such as "Lexol" and other brands), preferably containing beeswax and lanolin ingredients
- Prohibit oily care products (clogging pores, accelerating aging)
2. Operating Frequency and Method
- Care once every 3-6 months, and can be increased to every 2 months when the environment is dry.
- Take the size of a soybean and apply it thinly in small circles on the entire skin using a lint free cloth. Let it sit for 20 minutes and then polish it unidirectionally with a clean cloth.
Environmental protection: Avoid light and moisture, prevent physical damage
- Light: Keep away from windows/heating, UV rays can cause leather to fade and become brittle (UV resistant film can be applied)
- Temperature and humidity: ideal humidity of 40%~60%, use a humidifier when it is too dry (avoid direct spraying of leather); Dehumidification is required during the rainy season
- Physical protection:Avoid contact with sharp objects (keys, pet claws), and the seat cushion can be covered with breathable linen pads to distribute pressure.
Regularly change the position of the cushion to reduce local pressure marks.
Absolute Taboo:
These behaviors will permanently damage Aniline leather!
| Behavior | Consequence | Alternative Solutions |
|---|---|---|
| Wash with a damp cloth | Cortical swelling, hardening, and cracking | Use only dry or slightly damp cloth to wipe points |
| Spray perfume/alcohol | Dissolve natural oils and leave white spots | Stay away from leather before use |
| Drying with hair dryer/iron | High temperature causes shrinkage and brittleness | Natural shade drying (24–48 hours) |
| Cover with plastic cover | Dampness breeds mold | Use cotton dust cover (remove weekly for ventilation) |
Repair and Professional Maintenance:
- Scratches/indentations: Gently rub with fingertips to promote oil secretion and repair; Deep scars require leather filling paste and professional repair
- Mold: Immediately treat with leather specific mold inhibitor to avoid spreading
- Every 2 years, please have a leather maintenance institution perform deep cleaning and glazing care to restore the activity of the leather surface
Summary: Core Principles of Aniline Leather Maintenance
- Less intervention, more prevention: daily dust removal+regular nourishment as the main approach, avoiding any violent cleaning.
- Nature first: Preserve the breathability of pores and prohibit chemical coverings.
- Time Appreciation: Slight scars and gradient patina are the medals of natural leather, without the need to pursue perfection and flawlessness
The scarcity of all green leather (only 5%~8% of cowhide meets the standard) determines its collection value - with proper maintenance, a all green leather sofa can be used for more than 30 years, becoming increasingly warm and profound over time, and becoming a inheritable home art piece.
2. Nubuck leather
Nubuck leather: Gently polish the grain layer to create a velvety texture.
Gloss/Touch: Matte, soft, with a touch like velvet.
Advantages:
1. Unique Texture
The surface has been polished and corroded to present a matte frosted effect, with a soft and velvety feel, visually understated and luxurious.
2. Strong Breathability and Durability
Usually, a thicker first layer leather embryo (1.5-2.5mm) is selected, which has good breathability and better tear and wear resistance than ordinary leather.
3. Widely Spplicable Scenarios
Commonly seen in high-end furniture, luxury car interiors, and other high-end products, showcasing a sense of quality.
Daily Maintain:
- Special tools: Use a specialized cleaning brush (soft and fine sandpaper) or eraser .
- Avoid direct use of water: Do not use a damp cloth to wipe the nubuck(suede) leather directly, as this may cause the range of dust to expand.
- Dust treatment: For dust, it is recommended to use a large and soft brush ( soft and fine sandpaper) to lightly brush or bounce the surface, gently removing the dust.
- Stain treatment: For stains that are difficult to remove, you can first use a damp cloth to gently press and dip to remove the stains, or use a soft sandpaper to carefully wipe them off, and then use the corresponding color rejuvenator for refurbishment.
- Oil stains treatment: If it is oil stains, you can use flour to absorb the oil stains, and then gently brush the flour away.
- Water stain treatment: When encountering water stains, it is advisable to avoid drying them with hot air as much as possible. Instead, gently pat them dry with a dry towel and let them air dry naturally.
Maintenance: Keep away from sunlight and damp places.
Natural Air Drying: After cleaning, the nubuck(suede) leather items should be placed in a ventilated and cool place for natural air drying, or a hair dryer should be used to speed up the drying process, and the temperature should not be too high to avoid damaging the leather.
