Interior Drill Brush Guide Estimated reading: 2 minutes 1788 views Summary: Drill brushes can save time on cleaning some areas, but they aren't meant to be used on many surfaces. Drill brushes are plastic bristles that can be attached to a powered drill chuck to save time on scrubbing. While it’s tempting to go wild with them and use a drill brush on everything, they can cause damage if used improperly. What can I use a drill brush on? Drill brushes are great on hard surfaces such as rubber floor mats and large areas of hard, scratch-safe plastic like truck beds and plastic floors. Use them in combination with an all-purpose cleaner (APC) for a good deep clean. Please make sure the plastic is actually scratch safe! Many automotive surfaces are covered in a foam or soft touch layer or whatever car manufacturers may think of in the future that removes their scratch safety. If it feels soft, don’t use a drill brush on it. If it’s hard, test in a small spot first just to be sure. Using a drill brush on carpet and cloth seats You can use a drill brush on fabrics, but only do it as a last resort. If you already did a pass with a regular fabric brush or a scrub pad and that did not help, the drill brush can be a viable last resort tool for fabric cleaning. The stiff bristles of a drill brush at high speed can damage and wear out fabric, so be cautious. Many drill brush kits come with different bristle options. Always used the softest available – it’s usually white or lighter than the others. Keep the super hard ones for cleaning in your house instead.
