Let’s dive into the steps to effectively Clean Stainless Steel Signs.
Stainless steel signs, especially the popular backlit channel letter variety, are highly sought-after by businesses for their modern and durable signage solution. However, over time, these signs can accumulate dirt and grime, diminishing their visual appeal. Proper cleaning and maintenance are crucial to preserving the pristine appearance and longevity of stainless steel signs. This comprehensive guide focuses on cleaning backlit channel letter signs but can be applied to other types of stainless steel signage as well.
Stainless steel signs, specifically backlit channel letter signs, are illuminated three-dimensional signage consisting of lit letters. These letters are internally illuminated by a light source housed within the sign. Enclosed within a rectangular panel or channel, the letters are commonly made of aluminium with coloured acrylics on the sides and backs, while LED lighting illuminates them from the front.
Stainless steel signs from reputable suppliers like SignsAtelier come without a transparent poly coating. While stainless steel is less prone to staining or corrosion than other metals, regular cleaning is essential to uphold its original shine and corrosion resistance. It is recommended to clean and inspect stainless steel signs every three months to ensure longevity and a pristine appearance.
Stainless steel’s corrosion resistance is due to a thin layer of chromium oxide. Exposure to environmental pollutants or mineral-rich water can compromise this layer, reducing its resistance to corrosion. Therefore, routine cleaning not only improves the signage’s appearance but also maintains the metal’s integrity. Neglecting cleaning can lead to a buildup of dirt and grime, detracting from the sign’s aesthetic appeal and potentially damaging the stainless steel surface over time.
Cleaning stainless steel signs is simple with a mild detergent and warm water. You can use a mild, non-abrasive cleaner or chemical if necessary. Harsh cleaners like Comet or Softscrub should be avoided as they can scratch the surface and contain chloride compounds that may induce corrosion. Following these steps ensures the cleanliness and shine of stainless steel signs.
Additional cleaning may be needed for tougher dirt or stains, using household stainless steel cleaners like “Kleen King.” Always wipe the letter faces in the direction of the grain to avoid streaks or scratches. A high-quality stainless steel polish such as Wenol and a soft cloth can be used for polishing. Protect against fingerprints and smudges by handling stainless steel with clean gloves or clothing and avoid greasy cloths during cleaning. Store signs in a clean, dry area when not in use to prevent dust accumulation. Covering the signs with a soft cloth or plastic wrap adds an extra layer of protection.
Fingerprints and stains can impact the appearance of stainless steel signs but rarely affect corrosion resistance. You can easily remove fingerprints using glass cleaner, white vinegar, or baking soda paste applied with a soft cloth. Rinse thoroughly with warm water. Avoid cleaners with chlorine and opt for acetone, methyl alcohol, or mineral spirits for effective stain removal.
Local pollutants like smoke and airborne dust require more than just cloth wiping. Avoid using abrasive pads or stiff brushes on signage to prevent damage.
No Need for Concentration: Dilute mild soap for cleaning. Essential car shampoos or wax additives are suitable for stainless steel surfaces. Dishwashing detergents should be avoided to prevent damage. Glass cleaner in a spray bottle can be effective for cleaning.
Clean signs section by section to thoroughly tackle dirt and ensure proper drying before moving on to the next section.
By following these cleaning and maintenance tips, you can ensure your stainless steel signs maintain their pristine appearance and longevity, enhancing your business’s aesthetic appeal.
