Detail Factory Synthetic Detailing Brushes vs Adam's Polishes Hand Held Boar's Hair Brush
Which should you buy? Our verdict on both, pulled from our full The Best Detail Brushes: 4 Compared (and One to Skip) comparison.
The synthetic set is the only product here built with no metal in it, which eliminates the ferrule as a scratch risk rather than asking you to be careful. The Adam's is the most informative page, publishing dimensions, naming epoxy set construction and stating which finishes it should not touch.

Detail Factory Synthetic Detailing Brushes
Buy itCompletely metal free, which removes the one part of a detail brush that can actually mark paint.
- Stated as completely metal free to help prevent accidental scratches, which addresses the ferrule directly.
- Ultra-soft synthetic bristles built with chemical-resistant materials, so wheel cleaner and degreaser do not degrade them.
- Aimed explicitly at scratch-prone surfaces: piano black interior panels, instrument clusters, infotainment screens and around badges.
- Ergonomic handle with a textured grip that stays steady wet, balanced at the grip to reduce fatigue.
- No dimensions published for any size in the range.
- Ultra soft means it will not shift bonded brake dust or baked-on grime.
- Sold in two-packs and combos across ten colourways, so working out what you are buying takes a moment.

Adam's Polishes Hand Held Boar's Hair Brush
Buy itA block-style hand brush rather than a round detail brush, and the only page here giving dimensions and anchoring.
- 12 inches long with 4 inch bristles, the only full set of dimensions published in this comparison.
- Epoxy set construction stated explicitly, which is what stops boar hair pulling loose in use.
- Long bristles reach into wheel faces, grille slats and door shuts that a shorter brush cannot.
- Stated as safe on all finishes, with a caveat rather than a blanket claim.
- Adam's says it is not recommended for flawless finishes and points you at a microfibre wash mitt instead.
- A block brush rather than a round detail brush, so it covers area and will not reach into a vent or a badge surround.
- Four inch bristles are long enough to flex a lot, which costs you control in tight spots.
