Marshalltown 6524: 20-Inch Acid Brush for Mortar, Concrete & Tools | Made in USA

Overview

The Marshalltown 6524 acid brush is a purpose-built long-handle tool designed to help you tackle tough masonry cleanup. With a generous 20-inch reach, it allows you to access mortar and concrete residues on bricks, wood forms, and metal tools from a comfortable distance. The brush combines practical design with durable materials to support cleaner work sites and more efficient maintenance of forms and components.

Key benefits and practical uses

• Designed for use in acid solutions, enabling effective mortar removal on bricks and blocks
• Ideal for clearing concrete residue from wood or metal forms and attached tools
• Sturdy Tampafil plastic bristles build a reliable cleaning surface that resists wear
• Bristles are secured in a high-tensile strength foam plastic block for stable, extended use
• 20-inch length provides leverage and reach in tight or elevated work areas
• Proudly made in the USA with global materials for consistent quality

Real-life scenarios commonly benefit from this brush: you can approach mortar buildup on brickwork from the ground without kneeling, rinse concrete from forms after pours, and refresh tools that have gathered masonry grime. The combination of a long handle and durable bristles supports controlled, steady scrubbing rather than abrasive scrubbing by hand.

Materials, build, and quality you can count on

The Tampafil bristles deliver a robust cleaning action while remaining flexible enough to reach corners and crevices. The foam block provides solid support, helping bristles stay aligned during use. The 20-inch handle is balanced for comfortable handling, reducing hand fatigue during longer cleaning sessions. This brush is manufactured in the USA, reflecting MARSHALLTOWN’s commitment to dependable masonry tools.
