Granite measuring instruments are precision measuring tools, and the cleanliness of their surfaces is directly related to the accuracy of measurement results. During daily use, the surfaces of measuring instruments inevitably become contaminated with oil, water, rust, or paint. Different cleaning methods and maintenance measures are required for each type of contaminant to ensure the long-term high accuracy of the measuring instruments.
Oil stains are one of the most common contaminants and can originate from lubricants or grease in the operating environment. Oil stains not only affect the appearance but can also penetrate into the pores of the stone, interfering with measurement accuracy. Once oil stains are detected, immediately remove the surface grease with a clean, soft cloth. Then, use a neutral or slightly alkaline stone cleaner to clean the surface, avoiding acidic or strongly alkaline cleaners that may damage the stone surface. After applying the cleaner evenly, gently wipe with a soft cloth to dissolve the oil. Rinse with clean water and wipe dry. For stubborn oil stains, repeat cleaning or use a paste cleaner for a deeper clean.
Water stains are typically traces left behind by evaporation of water from the surface. While water stains have a minimal impact on measurement accuracy, long-term accumulation can affect the appearance of the measuring instrument. Keeping the measuring tool surface dry is crucial. Wipe away any moisture immediately. For existing water stains, allow them to air dry before gently wiping with a soft cloth. To further prevent water stains, apply a stone protectant to the measuring tool surface to create a protective film and reduce moisture penetration and residue.
Rust stains typically form when rust or iron-containing materials come into contact with the measuring tool surface. This not only affects appearance but can also interfere with measurement accuracy. To clean rust stains, first remove surface rust with a soft cloth or soft-bristle brush. Then, gently wipe with a specialized stone rust remover or a mild acidic cleaner to dissolve the rust. Rinse with clean water and wipe dry. For stubborn rust stains, repeat the process or use a rust remover paste for deeper treatment.
Pigment stains may be from paint, ink, or other colored substances, affecting both aesthetics and accuracy. To clean, first gently wipe the surface with a soft cloth, then use a stone-specific pigment cleaner or decontamination paste. Chemical solvents may be used with caution if necessary. Apply the cleaner evenly and gently wipe the surface. Rinse with clean water and wipe dry. For particularly stubborn stains, moderate surface abrasion is recommended, but be gentle to avoid damaging the stone.
During the cleaning process, avoid scratching the measuring tool surface with hard objects to prevent scratches that could affect accuracy. Any stains should be cleaned promptly to prevent them from becoming difficult to remove and affecting measurement accuracy. Additionally, regular maintenance of granite measuring tools, such as applying protective agents and light polishing, not only prolongs their lifespan but also maintains their measurement stability.
Through effective stain removal and regular maintenance, granite measuring tools can maintain high accuracy and excellent appearance over time, ensuring optimal performance for precision measurements.
