Fried fish Friday, stirred a scoop in while the oil was still hot, ate dinner, came back and it was a solid caramel disc. Scraped it into the bin. No jar, no funnel, no drips down the cabinet.

I argued with my wife that flour would do the same thing. It doesn't - flour just makes greasy sludge. This actually sets. I was wrong and I'm fine with it.

Apartment, no yard, no disposal. I basically stopped frying because I never knew what to do with the oil. Now it goes in the trash as a block. I've fried three times this month.

Ventra™ GreaseLock is a 100% plant-based powder that turns used cooking oil into a solid block you can lift out of the pan and drop in the trash. No pouring, no funnel, no jar on the shelf, nothing going down the drain.

It works by gelling the oil rather than absorbing it - so unlike flour, oats or cornstarch, you get a firm, liftable disc instead of greasy sludge. Works with vegetable, canola, peanut, sunflower, soybean and corn oil.

One 100g tub covers roughly 48 cups of oil. Two-year shelf life, so it lives in the cabinet until the next fry night.

1. Finish frying. Turn off the heat and remove the food. The oil must still be hot - 170°F or above.

2. Sprinkle & stir. One scoop per cup of oil, straight into the pan. Stir until fully dissolved.

3. Let it cool. Around 30 minutes for a shallow pan, up to an hour for a quart in a deep fryer. Nothing to watch - walk away and eat.

4. Lift & toss. Scrape or cut the solid disc out with a spatula and put it in your household trash.

Does not work on oil that has already gone cold - reheat it first.

100% plant-based, naturally derived, non-toxic and food safe. OU Kosher (Pareve) certified.

It's a gelling agent, not an absorbent or a cleaner - it raises the melting point of the oil so it stays solid at room temperature, then lifts out with the block rather than staying behind in your pan.

Packed in a recyclable paperboard tub with a measuring scoop included. Two-year shelf life.

30-day money back guarantee - try it on your next fry night. If it doesn't do exactly what we say, tell us and we'll refund you.

1 year warranty on every tub.

Karen W.
The pot of cold oil on the back burner was a weekly guilt trip in this house. Now it's handled before I've finished the dishes.
Tony B.
Threw out four old grease jars from under the sink the week this arrived. One tub lives in the cabinet now and that's the whole system.
Alicia M.
Bacon grease was always the awkward one - too much for a paper towel, not enough for a jar. Half a scoop and it lifts out of the skillet.
Dennis K.
Deep fryer, about a quart of peanut oil. Stirred it in hot, left it alone about an hour, came back to one solid puck. Cut it like flan and binned it.
Sofia L.
Skeptical it would do anything to canola, since that never firms up on its own. It did. Pan tipped sideways and nothing moved.
Ray H.
Turkey fryer after Thanksgiving used to be a two-day job in the garage. Scooped, waited, blocks in the bag, done the same night.

The cooking oil question, answered

Don't Pour It Anywhere. Turn It Into a Block.

One scoop per cup into hot oil, stir, wait - then it's "so easy to just scrape into the trash." No jar, no funnel, no drain.

One tub handles 48 cups of oil.

Every fry night ends the same way

The Best Part Of Dinner Leaves The Worst Part Of The Night

A heavy Dutch oven of cooled brown cooking oil pushed to the back of a cold stove, with mismatched grease jars on the shelf behind itstill there Saturday morning

The jar under the sink

deferred · never dealt with

"I've been saving and using old pickle and salsa jars to pour and dump my use cooking oil."

Down the drain, hoping

congeals downstream

"I no longer have to worry about clogged kitchen pipes."

Flour in foil

soaks · still a greasy mass

"Orrrrrr just pour it in foil and add flour to solidify."

Too small for a jar

no move at all

"Not enough to do either of those options but too much to mop up with a paper towel."

Every one of these was a workaround for a problem that never had a proper tool. The pouring step was the flaw, not you.

 
 
The whole method

Sprinkle It In. Walk Away. Throw It Out.

Four steps, and you're already standing in the kitchen for three of them.

1

Sprinkle it in hot

One scoop per cup, straight into the pan. Oil must be 170°F or hotter.

2

Stir until dissolved

It makes an oddly satisfying crackling sound for a minute.

3

Walk away and eat

About 30 minutes for a third of a cup; about an hour for a quart in a fryer.

4

Lift it, toss it

Scrape or cut it out - it cuts just like flan - straight into the trash.

It does not work on cold oil. The oil has to still be hot when you sprinkle - 170°F or hotter.

The block does not slide out on its own. You scrape or cut it out with a spatula or knife, and the pan comes up pretty clean.

 
 
Same oil. Same pan. Same tilt test.

Flour Soaks It. This One Turns It Solid.

Absorbing and solidifying are not the same job. Watch what happens when you tilt the pan.

Flour, oats, cornstarch
A pan of used cooking oil with flour stirred in, tilted so the oily mixture visibly runs and streaks down the sidetilted · still running

Absorbents soak. You get an oily sludge you still have to wrap and carry.

Gelatin and chilling fail outright: "Oils like vegetable or corn or peanut or canola don't solidify no matter how long they sit."

GreaseLock
The same pan of cooled oil after GreaseLock, tilted at the same angle and completely solid, with the caramel-colored disc being lifted out wholetilted · not moving

A plant-based gel-in-oil thickener raises the melting point so the oil stays solid at room temperature.

One scoop per cup - no ratio guesswork, and the scoop is in the tub.
