In the old days there were cans of spray solvents that would clean PCB 100% clean. EPA squashed them and the products to replace them would leave a chalky film on the boards.
The technique I developed was to use a baking pan large enough to accommodate the size of the board. I put about a 1/8" deep bath of acetone in and placed the PCB in it solder side down.
It did a great job of dissolving resin and gum, dirt, grease, etc. Acetone will dissolve soft plastic so you have to be careful.
