Carls soap solution
Here you go - Its labled Carl's, but he will tell you he doesn't get the credit, but he put it out there so many times, we now attribute it to him. Carl is Carl Rosner. I also picked up a post to that thread by Behr (RIP)
CARL’S SOAP SOLUTION!
INGREDIENTS
Water
Dish Detergent
Rubbing Alcohol
DIRECTIONS
Fill a gallon jug with water and add one (1) or two (2) tablespoons of dishwashing detergent and one (1) tablespoon of vegetable oil (or Neem oil). Shake up the gallon jug to mix the ingredients.
Fill this solution from the gallon bottle into a spray bottle and just before using add 1 to 2 two caps full (from the rubbing alcohol bottle) of rubbing alcohol and spray immediately. If you do not use the full bottle of spray, I suggest the next time you are going to use the soap/alcohol solution add the same amount of rubbing alcohol again, since the alcohol will evaporate. I store this soap/oil solution in the gallon jug for months on end. It does not seem to go bad.
Spray on plants covering all leaf and stem surfaces. You may have to spray from three to four times with intervals of three days. I have eliminated almost any kind of pest that has attacked my trees, including scale.
I do not wash off the spray and have seen no adverse reaction to the trees from this mixture.

I have modified Mr. Carl’s recipe somewhat for my purposes and like the results...I use 1 table spoon of dishwashing detergent and 2 to 3 table spoons of 'Garlic Oil'...The addition of garlic makes the recipe even more thorough on insects plus many viral and bacterial pests...I have been using it for several years as a first attempt at controlling pests...
