How was limescale removal tested?
Sara IdenforsShort answer
To evaluate the cleaning performance of VästerbottensSåpa Fragrance-Free Limescale Remover, a laboratory test was conducted at Center For Testmaterials BV in the Netherlands. The product was tested against a standardized test material with dried limescale and soap deposits (DC-30). Water was used as a negative control. The cleaning effect was reported as the Soil Release Index (SRI), together with photographic documentation of the test surfaces.
Purpose of the test
The aim of the laboratory test was to document how effectively VästerbottensSåpa Limescale Remover removes standardized limescale and soap deposits under controlled laboratory conditions.
Water was also used as a negative control for comparison.
Testing laboratory
The test was conducted by:
Center For Testmaterials BV The Netherlands
The laboratory specializes in standardized testing of materials and cleaning products.
Tested product
The laboratory tested: VästerbottensSåpa Limescale Remover Fragrance-Free
The following was used as a negative control: water
The purpose of the control was to show how much cleaning is achieved without an active cleaning agent.
Test material
The laboratory used a standardized test material designated DC-30.
The test surface consisted of black ceramic with a defined deposit of:
- limescale
- soap residue ("soap scum")
This type of deposit is used to create reproducible laboratory tests.
This is how the test was conducted
Step 1
A standardized limescale and soap deposit was applied to the test surface.
↓
Step 2
VästerbottensSåpa Limescale Remover was applied to the test surface.
↓
Step 3
For comparison, a corresponding test surface was treated with water.
↓
Step 4
After cleaning, the proportion of the soil that had been removed was analyzed.
↓
Step 5
The result was documented using both:
- Soil Release Index (SRI)
- Photographs taken before and after cleaning.
How was the result assessed?
The laboratory used Soil Release Index (SRI).
SRI describes the proportion of the test soil that was removed.
- 100 % corresponds to complete cleaning.
- Lower values correspond to lower cleaning effectiveness.
Results
The laboratory reported the results in the form of:
- Soil Release Index (SRI)
- chart
- photographs of the test surfaces before cleaning
- photographs after cleaning with VästerbottensSåpa's limescale remover
- photographs after treatment with water as a negative control.
What does the laboratory test show?
The laboratory test demonstrates the cleaning performance of VästerbottensSåpa's limescale remover on a standardized limescale and soap test material under controlled laboratory conditions.
The report does not describe how the product works on all types of limescale deposits or in all usage environments; the results apply to the test conditions reported in the report.
Frequently asked questions
Where was the test conducted?
At Center For Testmaterials BV in the Netherlands.
What was tested?
VästerbottensSåpa's fragrance-free limescale remover was compared with water as a negative control.
What is DC-30?
DC-30 is a standardized test material consisting of a limescale and soap coating on a black ceramic surface.
What does Soil Release Index mean?
The SRI is a measure of the proportion of the test coating removed during cleaning. 100% corresponds to complete cleaning. VästerbottensSåpa's Limescale Remover removed 98%.
Were photographs included in the report?
Yes. The report includes photographic documentation of the test surfaces before cleaning and after treatment with VästerbottensSåpa's limescale remover and water.
Did the laboratory compare different brands?
No. The report covers only VästerbottensSåpa's limescale remover and water as a negative control.
Were both limescale and soap residue tested?
Yes. The test material consisted of a standardized coating of limescale and soap residue ("soap scum").
Conclusion
The laboratory test was conducted according to a defined method in which VästerbottensSåpa's fragrance-free limescale remover was tested against a standardized limescale and soap test material. The result was documented using the Soil Release Index (SRI) and photographic documentation, providing a transparent account of both the method and the results under controlled laboratory conditions.
