Great for greasy clothes such as mechanic uniforms
Great for washing mechanic uniforms! Leaves the clothes feeling cleaner and smelling better than regular laundry soap. I recommend mixing with your usual soap.

An Essential In Our Laundry Room.
I have been using Fast Orange Grease X for about 4 years. I own two Harley-Davidsons and perform my own maintenance and much of my own service. This stuff is terrific for getting oil and grease and greasy dirt out of shirts and jeans and shop towels and rags. It removes solvents and gasoline and their odors as well. While it will not completely remove a heavy bearing grease stain from a shop rag it will leave it serviceably clean. Most importantly it leaves the washer and dryer clean and decent smelling and that has kept my wife off my back for a long time. I've even used it on her kitchen towels after a round of heavy baking or cooking. It works extremely well on cooking oils and kitchen grease too.

Works true to its claim.
I appreciate this detergent for greasy construction clothing and dirty farm overcoats. Reduces odors, saves wear on my machines. An improvement should be made to bottle pour sour - it drips and splatters.

Works well with dirty automotive mess laundry.
This really works great. My mobile mechanic spouse really gets messy after some jobs and this detergent not only cleans his clothes but cleans the washer too. I do use more than the recommended amount on the label/cap but because the saturation of some of the messes. Motor oil, brake fluid, gear grease, hydraulic fluid, and more break down and come out of the clothing. Considering a drum order if possible.

Not any better than regular detergent, just more expensive.
I tried this when working for a shop that didn't provide uniforms so that I could keep my work shirts looking good. It didn't work any better than regular detergent, and it cost a lot more.

Nice smell
Nice citrus smell. Seems to do its job well. Doesn’t take much in a he washer.

Used and diluted
If I could give zero stars I would, I got this detergent and it was diluted with water and had spilled inside the box. Whoever had this used it previously. Returning it asap.

Clean maintenance uniforms
My wife has been using this on my uniforms for quite sometime and anyone who is a mechanic as I am would appreciate clean non greasy clothes when they put them on. It doesn’t remove all stains but has been great for most of them.
