Foam cleaners are cleaning products that produce foam when applied to surfaces. They are commonly used for cleaning various surfaces such as upholstery, carpets, rugs, and even certain hard surfaces like countertops and appliances. Foam cleaners typically contain surfactants, which are chemicals that help loosen dirt and grime, making it easier to remove. They can be particularly effective for lifting stains and dirt from fabrics without saturating them with liquid. Foam cleaners come in various formulations for different purposes and surfaces, such as carpet foam cleaners, upholstery foam cleaners, and general-purpose foam cleaners. It's important to follow the manufacturer's instructions when using foam cleaners to ensure effective and safe cleaning.
