I have no experience with Dragon Juice,.but I'm sure it's a much stronger product,..I know many guys use it so maybe they will jump in here. PP is just so cost effective and works so well at a very cheap price,..and I don't run into anything it won't work on where that type cleaner is required. We need a cost breakdown (price, shipping dilution rates) of Dragon Juice by someone who uses it regularly. Then we can all benefit from the information.

I am not sure Dragon Juice is a stronger product, it is just the right product. It removes most tiger stripes without the risk of removing the paint. There are instances where the paint will come off, but that is when the paint is fully oxidized and is ready to come off anyway. Some paint will come off with just plain water or the swipe of your finger. Dragon Juice is a concentrate that is shipped without water added. It requires water to activate it, and will not work straight from the jug.
The cost is $55 per gallon plus $15 shipping. So $70. The minimum amount of water that must be added is 4 gallons to the one gallon of Juice. So for the $70, you are really getting at the minimum, 5 gallons of product. I have never had to use it at that concentration. I use it at 10:1, and that where I start. Believe it or not, it works better diluted. I hear people squawking and balking at the $70 for a gallon, when in reality it is $70 for 5 or 10 gallons. Dragon juice is also great on tough algae stains. It's penetration properties are awesome. They re coming out with a dragon juice for flatwork, and I have pre ordered to try it out. Here is a recipe page from the website. Also I believe they sell quarts now, if $70 is too much to test it out.
Some common used Ratios but the list is Growing!
10/1 (pre-spray flat work heavy oil)
15/1 ( gutters)
16/1 (awning )
20/1 (pre-spray flat work med oil)
30/1
40/1 (commercial flatwork maintenance)
50/1 (carpet) (auto detail)
64/1 (heavy soiled window cleaning)
100/1 ÷ (injector ratio ) = downstream mix Flatwork
128/1 (Window cleaning) (carpet)
133/1 × (injector ratio) house washes
200/1 Flatwork
500/1 (roof mixtures)
All have been used the most frequently and reported for different situations, these are all Contractor reported ratios, so try different ones always. When testing always test a small area for color fastness and needed dilutions
