How does Subscribe & Save work?

Check the Subscribe & Save 15% box to lock in 15% off every order, shipped automatically on the 1st of each month. Subscriptions run on a 3-month minimum commitment; after that you can cancel anytime from your account. Refunds aren't available on subscription orders.

Can I mix different bottles in one bundle?

Yes. Choose 2 or more bottles, then tap any slot to swap in another 16oz Powell Headz product — Boat Butter, 6 AM Glass, Seat Scrub, Captain's Cologne, and more. You get $10 off every order of 2 or more bottles — mix and match however you like, all the way up to the fully customizable Dock Father Refill Kit (6 bottles).

What's the difference between the 16oz, the gallon, and the Dock Father?

The 16oz is the everyday size. The 1 Gallon jug is roughly 8x the volume for heavy users — the best price per ounce. The Dock Father is the complete kit: every cleaner, microfibers, and an organizer bag, plus 2 free bottles. Add either at checkout above.

What surfaces is it safe on?

Our 16oz cleaners are pH-balanced and safe across the surfaces you'll find on any boat — gelcoat, hull, glass, vinyl, foam decking (SeaDek and similar EVA pads), and carpet — with no bleach and no harsh solvents. Tested by real boaters on Lake Powell's mineral-heavy water.

How does the 30-day guarantee work?

Use it on your boat. If you're not blown away within 30 days, email us — we'll make it right, no questions asked. No restocking fees. Real boaters handle every return.

    Not your average
    marine cleaner.

    Boat Butter Water Spot Remover 16oz is purpose-built for boats — formulated and proven where the grime actually lives, not on a lab bench.

    Tested on the water

    Formulated and proven in real, mineral-heavy lake water — where most cleaners quit. Not a benchtop experiment.

    Safe on your surfaces

    pH-balanced and boat-safe across gelcoat, vinyl, glass, foam, and hardware. No bleach, no harsh solvents.

    One-pass clean

    Spray it on, wipe it off, back on the water. No hose, no bucket, no dilution, no endless scrubbing.

    Why It Works

    Made for the water
    it's used in.

    Powell Headz wasn't formulated in a lab. It was formulated on the water — where mineral-heavy hard water actually lives, where the sun bakes vinyl, and where the margin for error is zero. Then it gets tested every weekend by the boaters who use it.

    I've run through every marine cleaner on the shelf. Powell Headz is the only line I actually reach for every single weekend. Nothing else comes close.

    Why Powell Headz

    Not all marine
    cleaners are equal.

    Most marine cleaners are car formulas in different bottles. We're built for boats — by boaters — in hard water.

    FAQ

    Every question.
    Answered.

    Everything you need to know before you buy.

    How does the 30-day guarantee work?

    Use it. Clean your boat. If you're not blown away within 30 days, email us — we'll refund every dollar. No restocking fees, no multi-step return process, no questions that require explaining yourself. Real humans handle every return.

    Will it work on my boat?

    If your boat has gelcoat, vinyl, glass, foam decking, or carpet — yes. Built and tested for wake boats, pontoons, ski boats, and bass rigs in hard water. And if it doesn't deliver on yours, send it back inside 30 days for a full refund.

    What surfaces is it safe on?

    It's pH-balanced and tested on gelcoat, vinyl, glass, foam decking, chrome, stainless, decals, and vinyl wraps. No bleach, no harsh solvents, no surprises.

    How do I use it?

    Spray directly onto the surface, wipe with a clean microfiber, done. No dilution, no pre-rinse, no bucket. For heavier buildup, give it a few seconds to break down before wiping.

    How long does one bottle last?

    A little goes a long way. Because it's a concentrated, no-dilution formula, a single bottle covers many detailing sessions for most boat owners.

    Are the products made in the USA?

    Every Powell Headz product is formulated, bottled, and packed in the USA. Built for American lakes by American boaters.

    Is my payment information secure?

    100%. Checkout runs on Shopify's PCI-compliant platform with SSL encryption. We never see or store your card details.
