Since the dilution ratios differ, the HD Free Concentrate and the HD Free Pro Concentrate must be two different products.
Or are they?
There seems to be some areas of the dilution recommendations that I am not understanding.
From the HD Web-site:
"HD Free Waterless Car Wash Lotion Concentrate Mixing Instructions.
One 2 oz. bottle of HD FREE Concentrate makes 24 fluid ounces of ready-to-use spray.
Directions:
Empty the complete contents of one bottle of HD FREE Lotion Concentrate into an empty 24 oz. HD FREE spray bottle. If some lotion remains in the bottle, fill 50% with water, recap, shake and empty the contents into the spray bottle.
Next, fill the bottle to 1 inch below the top with pure water. If your water source is hard, use distilled or filtered water for best results."

"HD Free Professional Waterless Car Wash Concentrate Mixing Instructions.
HD FREE Concentrate is a heavy cream that requires proper mixing. Shake Mixed Solution Well Before Each Use. Each stroke of the pump dispenses 1 ounce of concentrate. For use by hand with a high volume trigger sprayer, dispense 3 pumps of HD FREE Concentrate in a clean 32 ounce spray bottle, fill with water, and shake well. For use by pressurized or electric sprayer, dispense 6 pumps into a clean 1-gallon jug, fill with water, and shake well."
Bear with me a little longer.
For a 24 oz. bottle, 2 oz. of HD Free Concentrate makes 24 oz. of finished product.
For a 32 oz. bottle, 3 oz. of HD Free Pro Concentrate makes 32 oz. of finished product.
A little difference, but not all that much.
Then I read that for a 1 gallon jug, 6 oz. of HD Free Pro Concentrate makes 128 oz. of finished product.
That's where I got lost.
2 oz. HDF, 22 oz. water - 11:1
3 oz. HDF Pro, 29 oz. water - About 10:1 (9.66:1)
Pretty close. Probably closer than most of us will measure.
6 oz. HDF Pro, 122 oz. water - About 20:1 (20.33:1)
Now that isn't close at all.
Is that a misprint in the mixing instructions or am I totally missing something?
