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.

Great for mechanics and kids!
I love using this product. As a home mechanic and I work on a lot of my cars during the weekend my coveralls are an absolute disaster by the end of the day. Simply take this down with all your other grungy junk down to the local laundromat, (why get your own machine dirty when you can ruin somebody else's?) and you will have thoroughly clean spot gree work clothes for your next project.

Bottle leaks (CHEAP BOTTLE CAP). Cleans diesel as advertised.
The cap of this bottle is EXTREMELY thin and cheap. Cracked in transport- same as others have reported. It's not leaking from the threading. I had a pair of elbow pads that had been left sitting in diesel for a day or two. Was unable to get the smell out hand washing, soaking with detergent, and machine washing. I used this product to soak (even though directions say this is unnecessary), then machine wash on hot. Diesel smell is gone. The perfume in this detergent is a bit strong, though I no longer get nauseous when wearing the elbow pads. 5 stars for cleanliness. 3 stars for the super cheap bottle. Guessing I lost a couple of loads of detergent from the leak.

Very good
Works great. Gets the grease out of my work clothes. It doesn't have a fresh smell but i just add a little regular detergent to the water and that helps. As far as cleaning grease and oil out you cant beat it.

It works(ish)
Now that I've used up the bottle, I can give an honest review. First let me say that the bottle is much smaller than anticipated for the price. (No, I didn't Google how to convert measurement). How long does it last? Well... As you can imagine, I bought this for my husband's work clothes. My first load of laundry with this detergant was Aug 26. I used 2 cap fulls for a large load. The bottle lasted me 12 weeks, which was equivalent to 12 loads of laundry (24 caps full) without any type of pre-treating stains. The bottle says "up to 40 loads" and I didn't even get half of that. Very disappointed with that part. All in all, it mostly works and I'd use it again, but I will not pay the prices they're asking for mediocre degreaser. It pulls out the grease, but not the smell. PSA:: Heavy soiled laundry will require a 2nd washing. Because of the price, my first load was washed with this and the 2nd with my regular detergent.

Leakage of detergent through the box it came in
Great detergent ever but will not order anymore! The last three I have ordered have arrived leaking through the box. Tried to return but shipping site would not accept because of wet sticky box. I would like to be refunded for the last three I purchased because a lot of the detergent had leaked out of the bottle. I’m so sorry about this because it is such a great detergent.

It works
This is a the perfect complement for the hand degreaser. I used in my hair and face and I felt clean after a day of work.
