Deep Cleaning: Our Gap Brush features ultra-fine PET bristles that are much harder than a toothbrush. The thin, long construction of the brush head makes it convenient for reaching deep into crevices and thoroughly cleaning corners such as the toilet bowl and shower door track. Whether it's the gaps around your kitchen sink, bathroom tub tile, shower door, or toilet seat, the Gap Brush can tackle them all. Premium Quality: The hard bristle scrubbing brush is made from high-quality plastic and stainless steel, ensuring durability and rust resistance for a long service life. Each package includes 3 of these handy cleaning tools, allowing you to keep one in the kitchen and one in each bathroom. Ergonomic Design: With its ergonomic handle, the flat Crevice Cleaning Brush is comfortable to hold and easy to use. It also features a small hole for easy hanging to save space and allow for quick drying.
