No scientific proof at all but it feels like washing powder does a much better job at removing stains than washing liquid.
It also seems more and more difficult to find washing powder in store as manufacturers are moving to liquid and even more a rip off - pods. Don’t get me started on these money spinners.
What is your experience and what works best?
Haven’t used dishwashing liquid, just powder and pods, and the powder works a lot better. But maybe only because the powder also goes in the pre-wash section.
For clothes, I’ve used liquid and sheets, and the liquid works better than the sheets.
