Electron1100
Sorry to resurrect the thread.
Based on your recommendations electron1100, I bought a small box of Tesco Colour Powder, a 10 wash size for £1.50, but now concentrated & like Ariel advertises 20% more cleaning powder per gram. It smells gorgeous, nicer than Ariel or Persil Colour actually, & I put a load of clothes on with it. Just general weekly school uniform, underwear, socks & other things. I used Hoovers A59' wash cycle at 40c & the washer is modern, it was new last year but I can safely say that wash results in a modern machine as brilliant. It dissolves rapidly & leaves no gunk in the drawer, foams up quite nicely during the wash & also rinses out quickly. Despite the fact it has no bleaching agents my laundry was left smelling fresh & everything was so clean. I'm so pleased with it.
