Small enough to spray with one hand, these foamers aerate cleaners to create a foam that breaks down dirt and grime. The foam is easier to see than liquid cleaners and clings where liquid cleaners might drip. They can also be used as sprayers. Swap out the included nozzles as needed—go from a fine mist for delicate surfaces to a powerful stream to remove stuck-on material. The polyethylene tank is lightweight and resists impact and chemicals. The Viton® fluoroelastomer seal resists chemicals too, so you can use these foamers with a variety of solvents and acids.
