Conclusions

What the laboratory test shows

✓ The soap produced a clear cleaning effect on old, dirty treated wood. After the second treatment, the laboratory assessed the cleaning effect as more significant than after the first treatment.

✓ Old wood was perceived as significantly softer after treatment. In the panel test, the treated wood surface was assessed as significantly softer than the untreated reference sample.

✓ Only minor differences were observed on newly treated wood. This is an expected result because new pressure-treated wood already has an intact surface layer and residual treatment agents from the factory, giving it a relatively even and smooth surface. This is a technical interpretation of the result—the report does not analyze the cause.

✓ The results are based on controlled laboratory experiments. All samples were treated using the same method, with a defined soap concentration, temperature, scrubbing process, and drying time before evaluation.

✓ The wood surface was assessed both visually and through a panel test. Because the wood’s natural structure made instrumental color measurement unsuitable, the cleaning assessment was based on visual comparisons, while the feel of the wood surface was assessed by five panel participants.

Important to know

• The report does not compare the soap with other cleaning products.

• The report does not investigate the chemical mechanisms behind the cleaning or softening effects.

• The report contains observations from a laboratory test and a panel test, but presents no statistical significance analysis or comparison between different products.
