濟南氣候多塵且夏季多雨，卷簾門軌道易堆積灰塵、泥沙及油污，若長期不清潔，可能導致門體卡頓、異響，甚影響使用壽命。針對軌道結構特點（凹槽窄深、易藏污），需采用針對性清潔方法，兼顧效果與操作。

　　Jinan has a dusty climate and rainy summers. The track of the rolling shutter door is prone to accumulate dust, sediment, and oil stains. If not cleaned for a long time, it may cause the door to jam, make abnormal noises, and even affect its service life. Based on the characteristics of the track structure (narrow and deep grooves, easy to store dirt), targeted cleaning methods should be adopted to balance effectiveness and operational safety.

　　清潔前的準備工作需到位。準備合適工具：細長毛刷（刷頭寬度 5-8cm，刷毛硬度中等，避免過軟無法頑固污漬）、吸塵器（帶細長吸嘴，口徑≤3cm，便于深入軌道凹槽）、抹布（選用不掉毛的微纖維布，避免纖維殘留）、中性清潔劑（如洗潔精稀釋液，濃度 5%-10%，避免使用強酸強堿，防止腐蝕軌道金屬表面）、小鏟子（塑料材質，邊緣圓潤，用于鏟除凝固的泥塊或膠狀物）。若軌道油污較重，可備專用金屬清潔劑（含檸檬烯成分，去污同時防銹）。清潔前需關閉卷簾門電源（切斷控制箱電源，確保操作），將門體降半開狀態（露出軌道中段，便于清潔），檢查軌道是否有變形（如凹陷、凸起），若有需先簡單修復（輕微變形可用橡膠錘輕敲復位），再進行清潔。

　　The preparation work before cleaning needs to be in place. Firstly, prepare suitable tools: a slender brush (with a brush head width of 5-8cm and moderate bristle hardness to avoid being too soft to remove stubborn stains), a vacuum cleaner (with a slender suction nozzle, diameter ≤ 3cm, easy to penetrate into the track groove), a cloth (using microfiber cloth that does not shed hair to avoid fiber residue), a neutral cleaner (such as detergent diluent, concentration of 5% -10%, avoiding the use of strong acids and alkalis to prevent corrosion of the track metal surface), and a small shovel (made of plastic material with rounded edges, used to remove solidified mud or gel like substances). If the oil pollution on the track is heavy, a specialized metal cleaner (containing limonene component, can be prepared to remove dirt and prevent rust) can be prepared. Before cleaning, it is necessary to turn off the power supply of the rolling shutter door (cut off the power supply of the control box to ensure safe operation), lower the door body to a semi open state (expose the middle section of the track for comprehensive cleaning), check whether the track is deformed (such as concave or convex), and if there is any deformation, it needs to be repaired briefly (slight deformation can be reset by tapping lightly with a rubber hammer) before cleaning.

　　基礎清潔步驟需按順序進行。先表面浮塵：用細長毛刷沿軌道長度方向反復清掃，清理軌道兩端（易堆積灰塵的死角），將毛刷深入凹槽底部，順時針與逆時針交替清掃，使灰塵松動。隨后用吸塵器吸走清掃出的灰塵、碎屑（吸嘴貼近軌道底部，緩慢移動，確保無殘留），若軌道內有較大雜物（如小石子、樹葉），需先用手取出（戴手套防劃傷），避免吸入吸塵器造成堵塞。對于附著的泥沙（濟南雨季常見），可用微纖維布蘸清水（擰半干）擦拭，濕布可吸附細小泥沙，避免揚塵，擦拭時需沿軌道凹槽來回拖動，確保邊角處都能擦到，若泥沙已干結，可先用濕布覆蓋 5 分鐘（軟化后再擦），減少擦拭阻力。

　　The basic cleaning steps need to be carried out in sequence. First, remove surface floating dust: Use a fine long hair brush to repeatedly clean along the length of the track, focusing on cleaning the two ends of the track (dead corners where dust is prone to accumulate). Insert the brush deep into the bottom of the groove and alternate clockwise and counterclockwise cleaning to loosen the dust. Subsequently, use a vacuum cleaner to remove any dust and debris (with the suction nozzle close to the bottom of the track, moving slowly to ensure no residue). If there are large debris (such as small stones or leaves) inside the track, it should be removed by hand (wearing gloves to prevent scratches) to avoid clogging caused by inhaling the vacuum cleaner. For the attached sediment (common during the rainy season in Jinan), a microfiber cloth dipped in water (twisted to semi dry) can be used to wipe it. The wet cloth can absorb small sediment to avoid dust. When wiping, it needs to be dragged back and forth along the track groove to ensure that all corners can be wiped. If the sediment has dried up, it can be covered with a wet cloth for 5 minutes (softened before wiping) to reduce wiping resistance.

　　頑固污漬處理需耐心操作。軌道內的油污（多來自門體潤滑脂或外界油污）可用蘸有中性清潔劑的抹布擦拭，擦拭時稍用力按壓，使清潔劑充分接觸油污，靜置 2-3 分鐘后再擦，重復 2-3 次可去除大部分油污。若油污凝固成塊，可用塑料小鏟子輕輕鏟除（鏟子與軌道呈 45° 角，避免用力過猛刮傷軌道表面），鏟凈后再用清潔劑擦拭。對于軌道與門體連接的滾輪軸附近，需用毛刷蘸清潔劑刷洗，軸上附著的油污（防止滾輪卡頓），刷洗后用干布擦干，避免水分殘留導致銹蝕。若軌道內側有銹跡（濟南潮濕環境易出現），可在除銹后（用細砂紙輕磨銹跡），涂抹一層防銹油（如縫紉機油，用量適中，避免滴落污染地面）。

　　The treatment of stubborn stains requires patient operation. The oil stains inside the track (mostly from the lubricating grease of the door body or external oil stains) can be wiped with a cloth dipped in neutral cleaning agent. When wiping, press slightly to allow the cleaning agent to fully contact the oil stains. Let it stand for 2-3 minutes and then wipe again. Repeat 2-3 times to remove most of the oil stains. If the oil stains solidify into lumps, a plastic spatula can be used to gently remove them (the spatula should be at a 45 ° angle to the track to avoid scratching the surface with excessive force), and then wipe them clean with a cleaning agent. For the area near the roller shaft connected to the track and door body, a brush dipped in cleaning agent should be used to remove any oil stains attached to the shaft (to prevent the roller from jamming). After brushing, dry it with a dry cloth to avoid residual moisture causing rust. If there is rust on the inner side of the track (which is prone to occur in humid environments in Jinan), after rust removal (gently grinding the rust with fine sandpaper), apply a layer of rust proof oil (such as sewing machine oil, with an appropriate amount to avoid dripping and contaminating the ground).

　　清潔后的養護與檢查不可忽視。用干抹布將軌道徹底擦干（尤其凹槽底部，防止積水導致生銹），若環境濕度較高（如雨后），可打開風扇對著軌道吹風 10-15 分鐘，加速干燥。檢查軌道內是否有清潔工具殘留（如毛刷斷毛、抹布纖維），可用吸塵器再次輕吸一遍。隨后測試門體運行：接通電源，操作卷簾門上下運行 2-3 次，觀察是否順暢（無卡頓、異響），若仍有輕微卡頓，可在軌道內側涂抹少量潤滑脂（選用鋰基潤滑脂，涂抹厚度≤1mm，避免過多沾染灰塵）。定期清潔周期建議：濟南春秋季多塵，每 2 周清潔 1 次；夏季多雨，每周 1 次；冬季可每月 1 次，根據使用頻率調整（如商業場所卷簾門使用頻繁，需縮短周期）。

　　The maintenance and inspection after cleaning cannot be ignored. Thoroughly dry the track with a dry cloth (especially at the bottom of the groove to prevent rust caused by water accumulation). If the environmental humidity is high (such as after rain), turn on the fan to blow air onto the track for 10-15 minutes to accelerate drying. Check if there are any cleaning tool residues inside the track (such as broken bristles or cloth fibers), and use a vacuum cleaner to gently suck again. Subsequently, test the operation of the door: turn on the power, operate the rolling shutter door up and down 2-3 times, and observe whether it runs smoothly (without any jamming or abnormal noise). If there is still a slight jamming, apply a small amount of lubricating grease on the inside of the track (using lithium based grease, with a thickness of ≤ 1mm, to avoid excessive dust contamination). Regular cleaning cycle recommendation: Jinan is dusty in spring and autumn, clean once every two weeks; Rainy in summer, once a week; In winter, it can be adjusted once a month according to the frequency of use (such as frequent use of rolling shutter doors in commercial places, the cycle needs to be shortened).
