The detailer's secret

Scrubbing is what wrecks your paint. Thick foam means you never scrub again.

Ask any detailer what separates a proper foam wash from a splash of soapy water & you'll hear two words: dwell time. A wash solution only cleans while it's sitting on your paint, & sprayed on as a liquid it sheets off in seconds. Foamed on shaving-cream thick, it clings for minutes: plenty of time for the active ingredients to break down the salt, lift the grime & encapsulate the grit before you rinse. Follow up with Salt Seal through the same cannon & now every wash leaves another layer of protection behind.

It clingsDense foam grips your panels instead of sheeting straight off. The thicker the foam, the longer the dwell time: & dwell time is cleaning time.= minutes on your paint, not seconds

It liftsWhile it sits there, the active ingredients work under the filth: breaking the salt down, lifting the mud & road grime off your clear coat & locking it up inside the foam.= encapsulated, not smeared around

It sheets awayRinse it off & the foam sheets away, taking everything it captured with it. Nothing scrubbed in, nothing swirled, nothing left behind.= no swirl marks, ever

Foam on · soak · rinse off

The perfect pairing

Pair it with Salt Exterminator & the whole trip comes off in minutes: salt, mud, red dirt & all.

Salt Exterminator is an all-in-1 4WD wash: it lifts & loosens mud & red dirt with its Deep Expansion Technology, cuts through road grime, & dissolves the ionic salt a plain rinse can't touch. Every one of those jobs needs time on your paint to happen properly, & time is exactly what thick foam buys. Sprayed on thin, the wash dries off before it's half done. Foamed on thick, it clings & dwells for minutes: the mud lets go, the grime lifts & the salt dissolves properly instead of being pushed around.

That's exactly what the Foam Thrower PRO was tuned for. The dilution dial & precision orifice lay Salt Exterminator on thick & even, & around 600mL of solution covers your entire 4WD: well under a dollar a wash. Even after you rinse, Salt Exterminator's rust inhibitors keep working on your paintwork.

One canister, one rinse, & everything the trip stuck to your 4WD is simply gone.

Chloride salts are hygroscopic: they drink moisture straight out of the air. So that invisible film left after a beach run doesn't dry out & die, it stays damp through every night, working on your paint edges, seams & every stone chip. Each chip & scratch becomes a tiny corrosion cell with an electrolyte sitting right on top of it. That's why 4WDs that "get rinsed after every trip" still end up with bubbling paint & rust freckles: the rinse moved the salt around, it didn't dissolve it. Salt Exterminator foamed on through the Foam Thrower PRO actually dissolves it: broken down where it sits, then rinsed away for good.

Salt Exterminator being poured into the Snow Foam Cannon canister

One solution, every mess
Salt, mud, red dirt & road grime: the foam gives it the dwell time it needs to work.

Under a dollar a wash
Only ~60mL of Salt Exterminator goes into each 600mL of solution: a 5L lasts 80+ washes.

Keeps working after the rinse
Salt Exterminator's rust inhibitors stay on your paintwork long after the foam is gone.

The old way

A sponge on a dirty 4WD is just sandpaper with soap on it

Come home from the beach or the bush & your paint is wearing a layer of salt crystals, sand & road grit. Rub a sponge over that & you're dragging it all across your clear coat, under pressure, lap after lap. That's where swirl marks come from: the spider-web scratches that light up in every sunset photo. Scrubbing more gently isn't the fix. Not touching your paint until the mess is gone: that's the fix.

Swirls stack. Every gritty wash adds another layer of fine scratches, the clear coat slowly dulls, & the only way back is a cut & polish: real money, & it removes clear coat you never get back. Buyers see it too. Tired, swirled paint tells a buyer it was cleaned rough, no matter what the logbook says. Foam first & the story flips: the foam floats the abrasive layer off before a sponge or mitt goes anywhere near your paint, so if you do run a mitt after, it glides over slick, nearly-clean paint instead of grinding grit into it. Same ten minutes of effort: & five years from now, your paint is the proof.

Touch-free first pass
The Foam Thrower PRO floats the grit off before a sponge ever goes near your paint.

If you still hand wash
The foam lubricates the surface, so the mitt glides instead of grinding grit into your clear coat.

Gets where sponges never have
Bull bar, flares, roof racks, snorkel, mirrors & every gap in between: foamed in one pass.

The pro upgrade

Every cannon makes foam. Very few make foam that actually works.

That foam bottle that came free with your pressure washer? It's watery for a reason: it's built to a price, & that price was zero. Same guts as the $30 clones: big sloppy bubbles, on the ground inside a minute, your wash going with them. Our Foam Thrower PRO is the one worth owning. A machined orifice that maximises pressure & aerates your wash into dense, clinging foam, bolstered high tensile internals & a dilution dial with real range: throwing foam thick enough to still be working when you come back to rinse it off. Detailer tested & approved for everyday commercial use, it turns the washer you already own into a pro detailing rig, for a fraction of the cost of one professional detail.

Every piece above is a stocked spare, so one worn o-ring only ever costs you a part.

How to use it

Fill it. Foam it. Watch the filth slide off.

Ten minutes in the driveway & the one job the kids actually volunteer for. Point the Foam Thrower at it & let the foam do the rest.

Filling the cannon canister to the mL mark

Fill & dial

Fill with your wash up to the mL mark for the strength you're after: Salt Exterminator is the go-to, handling salt, mud, red dirt & grime in one. Top up with water, set the dial around the middle, & the measuring marks mean your perfect mix repeats every wash.

Foam it

Start low & work your way up, wrapping your whole 4WD with the wide fan. Then step back & let the foam do the hard part for a few minutes. One rule: never let it dry on your paint, so find some shade on a hot day.

Rinsing the foam and the filth off top-down

Rinse & admire

Now rinse, working top-down. The foam lets go & takes the salt, mud & grime with it, leaving your paint so clean you can see yourself in it.

✦ WHAT REVIEWERS SAY

Reviewers keep coming back to the same things: the foam is thick & actually clings, the dilution dial makes it easy to get right, & paired with Salt Exterminator the salt film & road grime rinse off without touching their paint. Plenty mention it feels solidly made compared to cannons they've had before, & that one canister does the whole 4WD.
