Simple Green Pro HD Heavy Duty Cleaner Concentrate 1 Gallon Bottle

This stuff works wonders! It cuts through grease, grime, and buildup like a pro. I use it for tough jobs in my shop and around the house. The scent is light and not overpowering, and it’s super versatile. Definitely a solid go-to for deep cleans.

Had been using citrus-based bicycle degreasers for a while, but wanted something that was less expensive but still worked well. Did some research and found out was supposed to work well with ultrasonic cleaners (which I have) and be safe on aluminum parts. (which I also have)I've never been a fan of the original green Simple Green, but this purple stuff was cheap enough to try it, so I did, and I'm very, very happy with the results. It can be aggressively diluted and maintains excellent degreasing properties, and works amazingly well in the ultrasonic cleaner. Experiments with the full strength cleaner and diluted to 1:3 - 1:4 (cleaner to water) showed no difference in cleaning power, which is excellent as it makes the stuff last even more.The only issue I had is I left a couple short segments of bicycle chain in the degreaser overnight with the full-strength solution, and when I found it the next day, the Shimano chain was pretty heavily discolored. Interestingly enough, the KMC chains in the cleaner were unaffected. Generally, you don't want to leave anything in a strong degreaser for any amount of time, and this confirmed that.Beyond that, I've cleaned a chain that was on a bike that was subjected to REALLY heavy mud, and then pressure washed and greased with whatever was on hand and ridden for the rest of the week with nothing more than reapplication of lube - and the chain came out _spotless_.Very happy with this product, I'll gladly buy another when I finish the first -- but considering how well it cleans when diluted, that might be a while. Far, far more cost effective than small bottles of the citrus based degreaser I had been using previously.

One of those great items.This stuff really works great.Definitely get some

Honestly I love this stuff! I’m not a fan of the original Simple Green because I can’t stand the smell. I originally purchased this degreaser because I run a restaurant and we needed a degreaser that was safe to use on stainless steel, aluminum, tile, epoxy floors, etc. it is not easy finding an effective degreaser that is safe to use on aluminum, usually most chemicals will darken the aluminum and then it’s a real pain in the rear to reverse that chemical reaction.This cleaner is strong, effective, not corrosive and cost effective. It tackles the grease and grime that we have at the end of the day in our restaurant with ease. I’ve purchased this product multiple times and will continue to do so. Thank you Simple Green!

Put a diluted amount in ultrasonic bath. Drop barrel and components in and they come out like brand new in 15-20 minutes. This one won’t strip the finish or ruin the metal. 👍. Compared to the marketed products it’s cheap. Also I get about four cleanings. Awesome stuff.

I found Simple Green when I lived in CT on a lake with a septic system and I wanted to make sure nothing I used in my house would damage the environment if or when it leached into the groundwater. The Green is great - but, for really gross cleaning - this product is a step up! I use it for all my cleaning - diluted by 50% with water - including as a pre-wash spray on clothes for stains. I use it on all hard surfaces like kitchens and bathrooms and it does a great job without the toxicity of other cleaners. I highly recommend this product!

The pro HD simple green works great in my ultrasonic cleaner. Just a couple ounces and warm water. Cleans carburetors almost factory new. Does not etch aluminum like regular SG.
