Excellent material: The Antique Brass Thumb Turn is made of stain stainless steel, which has excellent strength and corrosion resistance. In a professional salt spray test, it was placed in a 5% sodium chloride salt spray environment for 720 hours, and only very slight signs of corrosion appeared on the surface, with a corrosion depth of less than 0.05 mm. This is because alloy elements such as chromium and nickel are added to stain stainless steel, which form a dense oxide film on the surface of the steel, effectively preventing the invasion of external corrosive substances. In actual use environments, whether it is a humid bathroom, kitchen, or a high humidity environment in coastal areas, this excellent corrosion resistance can ensure that the thumb knob maintains stable performance for a long time, and will not affect the appearance and use function due to rust, greatly extending the service life of the product, reducing the frequency of replacement, and saving costs for users.
Diverse surface treatments: Various surface treatments are available, such as Black PVD, Matt Antique Brass - PVD, Polished Brass/PVD, Polished Stainless Steel, Satin Brass PVD, and Satin Stainless Steel. Different surface treatments not only give the thumb knob a unique appearance, but also have their own functional characteristics. Take the Matte Antique Brass PVD treatment as an example. It gives the knob surface a retro bronze texture with a warm and low-key color, which complements various retro-style decorations. At the same time, the PVD coating has good wear resistance. In a professional wear test, the PVD-treated knob surface was subjected to 100,000 friction tests using friction equipment that simulates daily use. The coating was only slightly worn, which did not affect the overall appearance and performance. This allows the thumb knob to maintain a long-lasting appearance quality in different usage scenarios, meeting the user's dual needs for beauty and durability.

Regular cleaning: Regularly wipe the surface of the thumb knob with a clean soft cloth to remove dust and stains. This is an important step to maintain its beauty and performance. For minor stains, you can use mild soapy water to wipe, then rinse with clean water and wipe dry with a dry cloth. Avoid using cleaners containing chemical solvents or abrasive particles, as chemical solvents may corrode the surface coating, while abrasive particles will scratch the surface. Perform a comprehensive cleaning at least once a week. During the cleaning process, carefully wipe every corner of the knob, especially the part connected to the door lock, to prevent dust and stains from accumulating. Because the accumulation of dust and stains will not only affect the appearance of the knob, but may also enter the interior of the door lock and affect the normal operation of the door lock. Regular cleaning can maintain the gloss and texture of the thumb knob and extend its service life.
Check the tightness: It is very necessary to check the tightness of the thumb knob every 3-6 months. If the knob is found to be loose, it should be tightened in time with appropriate tools to ensure that it is firmly connected to the door lock. A loose knob may affect the operating feel, resulting in unsmooth operation, and may even cause the door lock to not work properly. When checking, check whether the screws at the connection parts show signs of rust. If so, you can use a rust inhibitor to treat them or replace them with new screws. Rust inhibitors can effectively prevent the screws from rusting further and ensure the stability of the connection. Keeping the knob tight can ensure that it always functions normally during long-term use, avoiding the inconvenience and potential safety hazards caused by looseness.
Avoid collisions: In daily use, be careful to avoid collisions between the thumb knob and sharp and hard objects to prevent surface scratches or deformation. If a collision occurs accidentally, check the condition of the knob in time. For minor scratches, you can use a repair paste similar to the color of the knob to repair it. The repair paste can fill the scratches and make them less obvious; for more serious damage, it is recommended to contact a professional maintenance personnel for replacement. When moving furniture or cleaning indoors, be extra careful to avoid the knob from being hit by external forces. Because collisions will not only destroy the appearance of the knob, but may also affect its internal structure, causing the knob to fail to rotate normally or problems with the connection to the door lock. Protecting the knob from collision can maintain its intact appearance and good performance.
Prevent corrosion: Try to avoid long-term contact of the thumb knob with acidic or alkaline substances, such as lemon juice, vinegar, detergent, etc. If you accidentally come into contact with these substances, rinse it with clean water immediately. In a humid environment, pay attention to keeping the area around the knob ventilated and dry to reduce the possibility of corrosion. You can apply a thin layer of anti-rust oil on the surface of the knob to enhance its corrosion resistance, but be careful to avoid the anti-rust oil from contaminating the surface of the knob and affecting the appearance. The application cycle can be determined according to the use environment, generally once every 1-2 years. Acidic or alkaline substances will corrode the surface coating and material of the knob, destroying its appearance and performance. A humid environment will accelerate the process of corrosion. Applying anti-rust oil can form a protective film, effectively preventing the intrusion of external corrosive substances and extending the service life of the knob.
Reasonable operation: When operating the thumb knob, avoid excessive force, and gently rotate it to complete the opening or closing operation of the door lock. Excessive force may cause damage to the internal structure of the knob or loosening of the connection with the door lock. If you find that the knob is not operating smoothly, you should check whether the door lock is stuck or has other faults, and do not forcefully rotate the knob. You can apply a small amount of lubricant, such as lubricating oil or silicone grease, to the rotating part of the knob to enhance its flexibility, but avoid the lubricant from getting on the surface of the knob. Excessive force will cause the knob to be subjected to excessive stress, which may easily cause damage to internal parts. Reasonable operation and appropriate use of lubricants can ensure the smooth rotation of the knob, improve its service life and operating comfort.
Winter protection: In the cold winter, if the ambient temperature is low, be careful to prevent the thumb knob from becoming brittle due to low temperature. Avoid hanging heavy objects on the knob or applying excessive external force to prevent the knob from breaking. At the same time, pay attention to maintaining the stability of the indoor temperature to avoid the impact of rapid temperature changes on the knob. In the cold northern regions, the temperature difference between indoor and outdoor in winter is large, and the knob may be affected by thermal expansion and contraction, causing the material to become brittle or cracked. Therefore, special attention should be paid to the protection of the knob in winter to avoid damage to the knob due to temperature changes and external forces. Keeping the indoor temperature stable and using the knob properly can ensure its normal use in winter and extend its service life.
