Works
We have a heating oil delivery truck. My husband constantly gets diesel on his clothes when doing deliveries. THIS IS THE ONLY thing that works. Finally Finally. It dissolves the diesel. Very effective. It is not cheap though worth it because thereโs nothing else Iโve found actually works. I donโt know if itโs skin friendly but itโs momma friendly

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.

Yays & Nays
Unfortunately, there was little to no protection with my order and it had came leaking a little. Not enough to get upset but enough for the box to be wet. Overall the soap is great and has a fresh smell that I love. From other reviews and personal experience, I believe it works well with most oil & grease smells/stains but it doesnโt fully help with hydraulic type oils or the smell of metal from shavings. It definitely helps with the smell not sticking as much or more to the clothes, but doesnโt completely get rid of it.

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.

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.

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.

Good laundry tough stain remover
Works well but itโs replacing Resolveโs Spray N Wash stain stick so nothing compares or is made as a comparable substitute. Gel doesnโt stay on stain as long as stick spread. I have treated yard, mechanic, garage, food stains 47 years. Works better than Tide Sport. I will buy again. Fast Orange and GoJo cherry hand scrub work well on hand grease stains.

Impressed with the results
perfect for removing fuel and diesel smells and cleaning oil staining, seems to take a few washes to removed long term staining but iโm impressed. using 1 cap full per wash on 40 degrees C, on a fuel truck drivers cotton/poly uniform.

Mechanics get this
Was so happy with this product. My partner is a mechanic and I was sick of seeing and smelling oil and fuel. This product says you don't need to soak but I use it yo pre soak his work clothes and the amount of oils it pulls out of the clothes is fantastic. Might just save my washing machine.
