Cleaning Effect of Laundry Detergents at Low ...

Abstract Lowering the washing temperature of laundry has environmental benefits, but consumers are reluctant to decrease the temperature in fear of not getting clean textiles. The objective of this study was to test eight leading laundry detergents for low temperature washing at 30°C and at 40°C. The cleaning effect was tested by measuring the reflection values of pre-soiled swatches after ...
