The Marsh Brush: Nontoxic Silicone Bottle Brush

The Marsh Brush — the best bottle brush you’ll ever own (and the last one you’ll need).

Made from premium nontoxic silicone, this brush is free of BPA, BPS, PVC, Phthalates, Lead, Teflon, and PFAS. No sketchy plastics. No toxic coatings. Just pure, durable materials that keep your Littles safe.

At 10.25 inches tall, it’s the tallest silicone brush on the market — and it’s built to clean everything: baby bottles, snack cups, smoothie pouches, breast pump parts, even your Stanley.

The bristle layout creates a rich, foamy lather. The seamless, one-piece design means no mold, no gunk, and no grime traps. And the wide suction base keeps it upright, dry, and off your countertops.

Dishwasher safe. Built to last for years.

If your current brush is flimsy, crusty, or just plain gross — this is your upgrade.
