The MouldLab Mold Surface Test is a fast and simple way to check whether surfaces are properly cleaned after mould contamination. The test detects protein residues and organic material that can act as a nutrient source for mould growth. If residues remain on a surface after cleaning, there is a higher risk that mould may return. This rapid test allows you to verify cleaning quality in just a few minutes. Simply swab the surface, activate the test, and observe the colour change directly in the test device. A purple colour reaction indicates the presence of protein residues, suggesting that additional cleaning may be required. No laboratory analysis or specialised equipment is needed – the test can be performed on-site within minutes. Key Benefits ✔ Rapid indication of organic residues linked to mould growth ✔ Results in 1–10 minutes ✔ Simple swab test – no laboratory equipment required ✔ Ideal for post-cleaning verification ✔ Provides quick documentation of cleaning effectiveness ✔ Suitable for both professionals and private users How the Test Works Swab the surface you want to test. Activate the reagent in the test device. Observe the colour reaction. Purple colour indicates the presence of protein residues that may support mould growth. Faster and darker colour reactions indicate higher levels of organic contamination. Recommended For This test is suitable for: Homeowners checking surfaces after mould cleaning Property managers and landlords Cleaning companies Schools, offices and institutions Maintenance professionals Indoor environment inspections Important Note This test detects protein residues and organic contamination, which may indicate conditions favourable for mould growth.It does not directly identify mould species or confirm active mould colonies. For confirmation of airborne mould contamination, we recommend combining this test with a MouldLab Air Test Kit. MouldLab Recommendation For the best assessment of indoor mould risk, combine this surface test with our mould air sampling kits, which detect airborne mould spores in the indoor environment.
