A cleaning product's foaming behavior often plays a big role for customers. A cleaner which foams well is considered more effective than a weak foaming cleaner. The Der SITA FoamTester offers customer oriented, scientific testing.
In industrial cleaning it is common to use the weak foaming cleaners. Too much foam prevents effective wetting and thus, the cleaning process. Foam generation can be oppressed with expensive de-foamers. Scientific testing of foam properties enables optimal use of de-foamers.
