Bisakah Spanduk Luar Ruangan Flex Backlit dicuci dengan pancaran air bertekanan tinggi?

Flex Backlit Banner Outdoor can be washed with a high-pressure water jet under certain conditions. These banners are typically made of highly waterproof and weather-resistant flexible materials (such as PVC or polyester-coated fabric), which are inherently resistant to rain and some degree of impact. Using a low- to medium-pressure water jet (recommended pressures not exceeding 1500 psi / 100 bar), along with a wide fan nozzle and maintaining a safe distance of at least 30 cm, can effectively remove dust, bird droppings, and light organic dirt from the surface of outdoor flexible backlit banners, making it an effective routine maintenance measure.

However, high-pressure water jets must be used with extreme caution to avoid damage to Flex Backlit Outdoor Banners. Excessive water pressure or close spray distance can create a strong physical impact, potentially damaging the banner's waterproof coating or even tearing the fabric. Furthermore, direct water impact on frame seams, joints, electronic component interfaces (such as LED light strip mounting areas or power cord inlets), or printed areas can easily cause irreversible damage such as debonding, water seepage, discoloration, or circuit failure. Therefore, high-pressure water jets should never be used as regular cleaning tools.

Overall, Flex Backlit Outdoor Banners can withstand moderate water jet blasting, but this requires significant skill and carries both risks and benefits. The most reliable cleaning method remains manual scrubbing with a soft-bristled brush and a neutral detergent, or gentle low-pressure rinsing with a professional spray system. If a high-pressure water jet is necessary, strictly follow the manufacturer's cleaning instructions, controlling pressure, angle, and distance, and avoiding sensitive areas. For stubborn stains and deep cleaning, it is recommended to seek professional outdoor advertising cleaning services to maximize the lifespan and visual appeal of these high-value advertising media.
