- Got this to use with my ultrasonic cleaner based on a recommendation to clean bike cassettes and chains. Normally I use a special chain degreaser to take off the old chain oil but I tried this instead in the ultrasonic and I swear it's like I just pulled the parts from the boxes they came in for the first time. I expected them to be clean, I wasn't expecting them to look almost brand new. I will definitely be buying this again

Simple Green Pro HD works great!
- I have a small engine repair shop and use Pro HD at 3:1 ratio in my ultrasonic cleaner. This stuff is incredible for cleaning any metal and hard plastic parts. I have cleaned literally hundreds of lawnmower, snowblower and weedeater carburetors with Pro HD and they come out like new every time. I'd give it ten stars if I could!!

Very heavy duty cleaner
- Keep in mind this cleaner needs to be diluted, but it is safe for alloy/aluminum surfaces which is very nice. You need to mix it either in a 1:3 up to a 1:13 ratio depending on the cleaning need. I did find it broke up built on grease etc. very well with very little elbow grease. It's really good for cleaning up tool without damaging the surface which is great for people that like to cleanup their tools after every job. Grab a quick spray bottle of this in the shop and you are ready to clean up almost anything. Another use I found for it was using it with my pressure washer on sidewalks and walkways, talk about easy removal of dirt and grime. I have used simple gree products for years, but this was the first time I used their professional grade stuff and it really does make a difference.

Good degreaser thats alloy friendly
- Used to clean and degrease a newly acquired motorcycle. This was the product of choice as it is safe for alloy/aluminum surfaces. Combined with some brushing it worked well for removing the grime and built up chain oil. This will remain my go to cleaner for my power equipment and automotive degreasing.

Strips off the built up machine cutting fluid
- I tried this on an old CNC machine at work to really give it a test. We usually use normal Simple Green and this stuff was Simple Green on steroids. It worked fantastically and I like that I can vary the strength to clean my parts. I tried letting some tools soak over night and they came out oil free.

Will never use another brand
- I first tried this out a couple weeks ago and it did an amazing job. The floors look almost new and the whole house smells better in general. A safe solution that keeps my safer than the harmful chemicals in other brands.

- I have been using this cleaner for about two weeks. It works awesome. It helps break through all the dirt, mud, and food that was on my tile floor. It also smells great. Good quality cleaner.

- This was a sample. I liked that I could determine what strength to mix up depending on my cleaning requirements. Worked every bit as good as the "green" simple green. This works just as well as other more expensive products I've purchased. When this is empty, I will buy the replacement. I was not aware of the ProHD before this survey sample was provided to me. I'm very glad to have found this product. I like how easy it was to mix, just remember to let it sit a few minutes before rinsing.
