Cleaning acoustic foam can be a tricky task, but it doesn't have to be. With the right knowledge and tools, you can easily keep your acoustic foam looking and performing its best. The first step is to take a cloth and dampen it with isopropyl alcohol. Rub the cloth over the acoustic foam to remove any dirt or debris.
Then, moisten another part of the cloth with warm water and rub it over the same area to get rid of the smell of alcohol. Finally, use a hair dryer to dry the foam. If you're cleaning PVC acoustic panels, you can use a low concentration of neutral soap in water. Apply the solution with a sponge or soft cloth by rubbing gently.
Avoid cleaners with abrasives, such as abrasive powders or steel wool, as these can damage the foam. Additionally, don't use cleaning products that contain ketones, kerosene, or petroleum products. For a more thorough clean, you can wipe the acoustic foam panels with a clean cloth in warm water. If they're very dirty, you can also use soap - just make sure it's not too strong to prevent the acoustic foam panels from degrading or damaging.
Lightly vacuuming or dusting is also recommended. You can also disinfect the panels with hydrogen peroxide or alcohol. Applying cornstarch with a toothbrush or other fine-bristled instrument and then vacuuming it is another effective solution. If your acoustic wall panels are wrapped in fabric, such as Guilford of Maine acoustic fabric, you should opt for a washable, acoustically transparent fabric. This will ensure that your acoustic panels remain clean and hygienic - especially if they're used in areas where food is consumed or children are present. Finally, remember that acoustic panels not only absorb sound to improve the acoustics of the room, but they can also be decorative and enhance the overall look of the space.
