Zep ZUHFD18 is a specialized aerosol degreaser that creates an expanding foam, specifically designed to cling to vertical surfaces. This "Fast Gasket" foam uses sodium metasilicate to provide a high level of chemical contact on engine blocks, backsplash tiles, or range hoods, preventing the rapid runoff common with liquid sprays. The foam is calibrated to remain stable for several minutes, allowing the surfactants to emulsify grease and carbonized oils effectively.
The high-pressure nozzle is useful for reaching into deep crevices, though users should be mindful of the high alkalinity of the formula. It can be aggressive toward certain plastics and non-anodized aluminum if left to dry, so a 30-second spot test is recommended. Because this is a heavy-duty product with a noticeable odor, it should be used in well-ventilated areas and requires a thorough water rinse rather than a simple wipe-off.
If you prefer a concentrated liquid that you can dilute yourself for various tasks, the Zep Heavy-Duty Citrus Degreaser is a high-yield alternative.
