Better than the regular simple grain
Crystal simple green is an industrial grade. That’s much better than the standard simple green that you can buy at your local grocery store. I have been using it for years. They only bad part is that it has been more expensive in the recent years. They also have an aircraft simple green cleaner that is simply amazing.

This cleaner prove to be for my bicycle workshop
I use this cleaner to remove grease and stubborn stains from bicycles. So far, I have no complaints, it works great and it has a good value.

Great, when properly used.
Not sure if ‘warmth, thickness, and sheerness’ serve any significance in the superiority of Simple Green Crystal. But…Years ago I was left with using SG Crystal as an alternative to the banned Petroleum Cleaning Solvent. I was so amazed with its capabilities of cleaning greasy, dirty parts, I bought it again. And now, I buying it by the 5 gallon pails. Good stuff.Yes, I find it works much better than the fragrance and color added formula. It’s Clear, so try not to drink or misuse it. That will only cause it to be less available and more expensive, due to a few less brilliant users.

This stuff is amazing. I wish I had found it earlier
This stuff is amazing. I wish I had found it earlier. I used it to clean the dried on grease on my range hood and stove. The range hood had grease built up for at least 5 years. It was pretty disgusting. I've tried to tackle it with vinegar and baking soda before and it did not work. So I always gave up thinking it would break before it became dangerous. However, I couldn't take it anymore. I purchased a bottle of this and I experimented. I was amazed at its cleaning abilities. I literally took off years of built up dried grease in a matter of 2 hours. The range hood is shiny again as is my stove. There is a light scent that is a mix between minty and citrus. It's not a bad scent. It fades very quickly. I'll be back for more. This would make maintenance a breeze now.

Removed axle grease from white car carpeting and headliner
Wow, awesome cleaner. I bought this specifically to clean real axle grease stains from the white carpet inside my Mercedes Benz. Yes, the carpet and headliner is white. The grease was black, and real axle grease, not just dirt and grime (bicycle grease). It was on the both the carpet and the headliner, which is notoriously hard to clean and easy to ruin. This cleaner is clear, only takes a little on a rag (I even watered it down to about 60% strength). It removed the grease and you can't see where I cleaned (compared to using a bleach-based cleaner which would have bleached the carpeting.I'm so happy I found this stuff. The interior of my car looks brand new now.

Works great!
Cuts the grease off of my appliances better than anything I’ve ever used. The smell can be off putting but it’s worth getting used too for the cleaning power. I used it on my stove without having to scrub just spray & wipe! Super easy to use! Only ⭐️⭐️⭐️⭐️ because it is pricey.

biodegradable water-based degreaser that works
I was skeptical that a water-based, biodegradable de-greaser could possibly be effective, but this worked like a charm on a grungy bicycle drive-train that hadn't been cleaned since I quit using organic solvents over a year ago. I wish I'd known about this earlier.By the way, to clean the chain, I used this with the Filzer chain cleaner, which worked much better than the Park chain cleaner which I tried and rejected because it didn't seem to work effectively and lost a lot of bristles.Also, fyi, this product can be diluted with water according to a dilution table that is available from the MFR website. I used about 1:5 for the chain and that seemed to work fine.

Won’t buy again.
The big gallon bottles that you mix with water work like magic. This stuff that’s already mixed must be like 90% water bc it doesn’t work at all. I won’t buy the premixed stuff again.
