Do try some ultradust guys. Its from s manufacturer that makes simple green products.
It runs around $.50-$.80 a gallon, because its a powdered concentrate.
In addition, it has addition agents, not only for degreasing, but for circuit board and electronic
parts.
All one needs is water, and the ratio that suits the project best.
Nothing I am getting rich on...just a superior product, thats easy to store, and no reason to pay for transport and shelf space for water.
