What happens if you leave the metal part of the brush in water for too long?

Short answer: it can damage the brush. Leaving the metal ferrule/metal parts sitting in water for long periods commonly causes corrosion, loosening of the bristles, and finish/handle damage.

Details and why it matters
- Rust/corrosion: ferrous metals (plain steel, iron) will oxidize and rust. Other metals (nickel‑plated, brass, aluminum, stainless) resist it to different degrees but can still tarnish or corrode in harsh conditions.
- Glue failure and bristle loss: water wicks into the ferrule and softens or dissolves the adhesive holding the hairs, so the brush sheds or the ferrule loosens.
- Handle damage: water wicking under the ferrule can swell or crack wooden handles and blister painted finishes.
- Mold/odour and staining: trapped moisture can encourage mildew and leave stains on the ferrule, handle or surfaces you put the brush on.

What to do if it’s already been soaked
- Rinse and dry thoroughly: towel off and dry bristles and metal; let the brush air‑dry completely (bristles pointing down or flat so water leaves the ferrule).
- Remove light rust: try white vinegar or a baking‑soda paste, scrub gently, then dry and oil lightly. For heavy corrosion replacement is usually best.
- If bristles are loose: you can sometimes reglue the ferrule with epoxy, but replacement is often cheaper and more reliable.
- Disinfect if needed (especially toothbrushes or makeup brushes)—replace if metal is pitted or shedding.

Prevention tips
- Don’t soak the whole brush—clean only the bristles.
- Rinse quickly and dry with bristles pointing down or lay flat so water doesn’t collect in the ferrule.
- Store brushes upright with bristles up or hang to dry after washing.
- Wipe metal parts dry after cleaning; oil lightly (mineral oil) if it’s plain steel and you want extra protection.
- Replace brushes that show heavy rust, loose ferrules or persistent odor.

If you tell me what kind of brush (paintbrush, makeup brush, toothbrush, etc.) I can give more specific cleanup and prevention steps.
