    その他In one illustrative embodiment, the pre-polish cleaner is formed

実験手順

In one embodiment, the pre-polish cleaner is formed from citric acid and potassium citrate, and has a pH in the lower end of the above-described range; more particularly it has a pH in the range of 2.5 to 4. In one illustrative embodiment, the pre-polish cleaner is formed by combining, with water, 40 g/l of anhydrous citric acid and 40 g/l of potassium citrate monohydrate. In other embodiments of the present invention, the cleaning solution is formed from a combination of citric acid and potassium citrate wherein the amount of citric acid is in the range of 0 to 40 g/l and the amount of potassium citrate is in the range of 0 to 40 g/l, and wherein the total number of g/l is greater than 0.
