High-quality materials and surface treatment: The Black Bathroom Thumb Turn Lock is made of brushed stainless steel, which has excellent strength and excellent corrosion resistance. In a professional salt spray test, the lock was placed in a 5% sodium chloride salt spray environment for 720 hours, and only very slight signs of corrosion appeared on its surface, with a corrosion depth of less than 0.1 mm. This is due to the reasonable ratio of alloy elements such as chromium and nickel in brushed stainless steel. These elements form a dense and solid oxide film on the surface of the steel, effectively preventing the invasion of external corrosive substances. The black PVD surface treatment further improves the performance of the lock. The PVD coating has good wear resistance. In a professional wear test, the surface of the lock was subjected to 100,000 friction tests using friction equipment simulating daily use. The coating was only slightly worn and did not affect the overall appearance and performance. This combination of high-quality materials and advanced surface treatment ensures that the lock can maintain a stable appearance and quality during long-term use, whether facing the high humidity environment of the bathroom or the friction and collision in daily use, greatly extending the service life of the product.

Clean the surface regularly: Wipe the surface of the lock with a clean soft cloth every week to remove dust and stains. For minor stains, wipe with mild soapy water, then rinse with clean water and wipe dry with a dry cloth. Avoid using cleaners containing chemical solvents or abrasive particles to avoid corroding or scratching the surface coating. Because chemical solvents may react chemically with the black PVD coating on the surface of the lock, destroying the structure and performance of the coating, and abrasive particles will leave scratches on the surface of the lock, affecting its appearance. When cleaning the indicator logo on the external panel, be especially careful not to use too much force to avoid damaging the logo. The indicator logo is usually delicate, and excessive force may cause the logo to fall off or become blurred. Regular cleaning can keep the black appearance of the lock as bright as new, extend its service life, and keep the lock in good visual effect at all times.
Check the mechanical parts: Every 3-6 months, check whether the thumb knob rotates smoothly and whether the bolt retracts and retracts normally. If you find that the rotation is stuck or the lock tongue is not flexible, you can apply a small amount of lubricant, such as lubricating oil or silicone grease, to the active part of the lock, but be careful to avoid the lubricant from getting on the surface of the lock. Too much lubricant may absorb dust, causing the surface of the lock to become dirty and affecting the appearance. At the same time, check whether the connection between the lock and the door is loose. If it is loose, use appropriate tools to tighten it in time to ensure the stability and reliability of the lock. Loose connection parts may cause the lock to move when it is stressed, affecting its locking and unlocking functions, and may even cause damage to the lock. Regular inspection and maintenance of mechanical parts can ensure the normal operation of the lock and reduce the probability of failure.
Avoid impact and scratches: In daily use, be careful to avoid impact and scratches on the lock. Inform users not to touch the lock with sharp and hard objects, and be careful to avoid them when carrying items. Sharp objects may scratch the surface coating of the lock, and the impact of hard objects may cause the lock to deform or damage the internal mechanical structure. If an impact or scratch occurs accidentally, check the appearance and function of the lock in time to see if it is damaged. For minor scratches, you can use a repair paste similar to the color of the lock to repair it; for more serious damage, it is recommended to contact a professional maintenance personnel for replacement to ensure the normal use and beauty of the lock. Timely treatment of damage caused by scratches and impacts can prevent further damage and extend the service life of the lock.
Prevent contact with corrosive substances: Try to avoid long-term contact of the lock with acidic or alkaline substances, such as lemon juice, vinegar, detergents, etc. If you accidentally come into contact with these substances, you should immediately rinse them with clean water. Acidic or alkaline substances will react chemically with the material of the lock, corrode the surface and internal structure of the lock, and affect its performance and life. In a humid environment, pay attention to keeping the area around the lock ventilated and dry to reduce the possibility of corrosion. A thin layer of anti-rust oil can be applied to the surface of the lock to enhance its anti-corrosion performance, but be careful to apply it evenly to avoid oil accumulation affecting the appearance. The period of applying anti-rust oil can be determined according to the use environment, generally once every 1-2 years. Anti-rust oil can form a protective film to prevent external corrosive substances from contacting the lock and protect the material of the lock from erosion.
Winter protection: In the cold winter, if the ambient temperature is low, be careful to prevent the lock from becoming brittle due to low temperature. Avoid hanging heavy objects on the lock or applying excessive external force to prevent the lock from breaking. Low temperature will make the material of the lock brittle, reduce toughness, and easily break when subjected to external force. At the same time, pay attention to keeping the indoor temperature stable to avoid the impact of rapid temperature changes on the lock. In extremely cold areas, you can wrap a layer of soft insulation material, such as insulation cotton, on the surface of the lock to play a certain role in insulation and prevent the lock from being damaged by freezing. Rapid temperature changes may cause stress inside the lock, causing problems such as cracking. Keeping the temperature stable can reduce this risk.
Maintenance when not in use for a long time: If the lock is not used for a long time, such as the house is vacant or the bathroom has not been used for a long time, the lock should be unlocked and a simple operation should be performed regularly (every 1-2 months) to move the thumb knob and the lock tongue to prevent the internal mechanical parts from rusting or getting stuck due to long-term inactivity. Mechanical parts that are inactive for a long time are prone to rust, causing the lock to fail to work properly. At the same time, you can apply a layer of anti-rust oil on the surface of the lock to form a protective film to further protect the lock. Before reusing the lock, clean and inspect it to ensure that it functions normally before putting it into use. Cleaning can remove dust and stains that may have accumulated on the surface of the lock, and inspection can find out whether the lock has been damaged or malfunctioned during long-term idleness, ensuring that the lock can be used normally and safely.
