BENZ RIDER:
I'm going to share with yall a little trick I learned
I agree the Car Soaps don't tell you except- "use 1 oz. per gallon..."
Who in the world has little one ounce measurement cups?
Thinking about this I got an idea.
You know those little cups you receive on the Nyquil Bottles, those little plastic cups attached to it?

Look at it carefully. They have measurements.
I measure out 4 of these cups to 4 Gallons of Water and it cleans wonderfully
No more guessing!

Guess what? When your done, the Nyquil Cup fits PERFECTLY on top of the
Shampoo Bottle.
Check it out. I think you'll be pleasantly surprised.
I quickly learned that in order to make the Cali Gold work it's best, don't add too much water...allow it to suds up real heavy and it works great...but if you follow the instructions it doesn't tell you how much/or less water to make it work the best. I literaly used only 3 big Gulps of water to 3 measured cups of Cali Gold and it works wonders.
