The product is diluted with water depending on the application and degree of soiling. An optimum effect is achieved at a pH value between 10.0 and 11.5.
The product can also be used for neutralisation after the application of acidic paint stripping products. To do this, first remove all dissolved paint residues from the surface with a brush and then spray it with water. The neutralising product is then sprayed on at 3 - 5 % by volume. After a short exposure time, rinse with fresh water.

By titration: 10 ml of the cleaning bath are added to a 250 ml Erlenmeyer flask and diluted with 50 ml of demineralized water. 5 drops of indicator solution methyl orange is added. Titration will be done with 0.1 M hydrochloric acid solution (HCl) until color change from yellow to red.
Concentration (vol.%) = [volume 0.1 M (HCl) in ml] x 1,32
If the pH and concentration are within the specified values, but the cleaning effect is no longer sufficient, the cleaning bath is exhausted and should be changed.
