We typically suggest a mixture of water and mild dishwashing soap, maintaining a ratio of 1 ounce of mild soap per gallon of water (approximately a 1:100 ratio). Apply this mixture with a soft, non-abrasive microfiber cloth, delicately rubbing the surface to eliminate dirt and stains. After cleaning, rinse the area thoroughly with clean water and gently wipe it dry. If disinfecting is necessary, you can incorporate up to one cup of bleach per gallon of water (a 1:16 ratio) or utilize a quaternary ammonium-based disinfectant such as Ecolab A-456-II.

When choosing a gentle detergent, opt for products labeled as "dishwashing" or "hand" soap in liquid form. Remember that the terms "soap" and "detergent" are often used interchangeably. Carefully review the recommended usage for each cleaner. An appropriate soap for wallpaper cleaning typically indicates mildness, safety, and gentleness, and may highlight qualities such as being non-toxic, eco-friendly, phosphate-free, additive-free, or skin-friendly.

Avoid the use of dishwashing tablets or detergents intended for dishwashing machines, as they may contain harsh abrasives that could harm your wallpaper. Additionally, refrain from common household cleaners, laundry detergents, solvent-based agents (such as lacquer thinners, nail polish remover, pine oil, or mineral spirits), and multi-surface cleaners, which often contain potent solvents that could strip wallpaper of its color.

As a general rule, if a cleaning product is in spray bottle or powder form, it's best to refrain from using it on your wallpaper to prevent potential damage.
