We’re Grease Buster, A Grease Fitting Cleaning Tool Brand

Every gearhead knows the gut-punch. You are deep in the guts of a dozer—sweating, cursing—working the grease gun until your knuckles turn white. You lock onto a fitting. Squeeze. Nothing. The Zerk is dead to you... a clogged scream for help from the machine. Enter the Grease Buster. American-made savior. It flushes the junk and keeps the iron moving.

The Science of Stuck

You gotta respect the lineage. Oscar Zerk invented the fitting in '29 to keep the good stuff in and the grit out. But there is a catch. That same tight seal acts like a tomb, baking old grease into something harder than a politician's heart.

Chemistry of Clogs

Grease isn't just goop. It is a sponge holding oil. Mix the wrong stuff—throw a lithium grease in with aluminum complex—and the matrix collapses. It separates... leaving a waxy brick that your hand pump can't move.

Hydraulic Ram Effect

We are talking brute physics here. A standard grease gun just pushes... static pressure. Boring. This tool strikes. When you whack the piston, you send a shockwave that spikes pressure far beyond your grip strength.

Thixotropic Breakdown

The vibration messes with the grease's brain. The high-frequency shock disrupts the internal structure of that waxy block... making it act like a liquid for a split second so the solvent can creep in.

Do It Right

Gut the tool and pour in real liquid. Kroil or acetone. No aerosols. The bubbles in a spray can act like tiny pillows... killing your shockwave. Snap the heavy-duty coupler on and tap. Don't drive nails—just induce vibration.

Warning: No Sealed Bearings

Seriously. Sealed bearings are a no-go. You will blow the seals out and be worse off than when you started. Stick to open bearings, bushings, pins, and U-joints.

The Solvent Science

Old timers aren't crazy; the acetone and ATF cocktail is legit. The acetone is the mule—thin and fast—carrying the lubricity of the ATF deep into the clog to dissolve binders. It works better. Period.

Grease Buster Bestsellers

Grease Buster Original (GB17)

This is the alpha. American steel that eats hammer strikes for breakfast. It doesn't shatter; it endures. The coupler actually grips—crank it down so it doesn't fly off when you tap. Dual O-rings keep the pressure where it belongs, not on your boots.

Pneumatic Piston Accessory

When grease is basically fossilized rock... bring the noise. This accessory swaps out the manual piston and fits a standard air hammer (.401 shank). Thousands of beats per minute. Vibrational warfare that jackhammers the clog on a microscopic level.

Grease Buster Hose Extension

Machinery is designed by people who never have to fix it. Fittings buried in U-joints or shielded shafts? The rigid tool is useless there. The hose snakes in. Five inches of reach. Just hold the body steady... don't let the flex steal your impact energy.

Why Burn Money?

Why Customers Choose Grease Buster

Do the math. A seized pin costs five grand to fix. This tool costs sixty bucks. It pays for itself the first time you don't have to torch a bushing out.

Stop the Torch

Heating a pin destroys the temper... makes it brittle. Melts the seals. Plus, setting a combine on fire is generally considered bad for business. Fix it in fifteen minutes instead.

Kill Downtime

A mining truck sitting idle bleeds money—five large an hour—just evaporating into the ether. You can't afford that.

Utilitarian

We keep the lineup tight. Utilitarian. Tools that live in chests from Omaha to Odessa.

Grease Buster Reviews

The proof is in the grease. We get photos and letters from guys who were ready to torch their machines. Miracle workers... or at least that's what they tell us.

I've been wrenching on heavy equipment for twenty years. Torches destroy the temper in the steel, drills are a nightmare... I honestly thought this tool was a gimmick. I was wrong. I had a pivot pin on an old Deere that hadn't seen grease since the Carter administration. Filled the Buster with Kroil. Tapped it about ten times. Boom. The black snake of death popped out followed by fresh blue grease. It pays for itself in one use.

Look, it ain't magic. If the line is physically crushed, physics won't save you. But for dried sludge? Yeah. It works. I run a farm, and setting a combine on fire with a torch is generally bad for my bottom line. This thing is safer. Just don't use WD-40 in it, use something real like acetone or transmission fluid.

My husband was ready to scrap the mower deck because of a seized spindle. I bought this. He laughed. Ten minutes later he was mowing the lawn. Who's laughing now? The tool feels heavy in your hand... real quality, not that plastic junk you get these days.
