I was inspired by the '3 loads a day' washing thread to be a bit more of an 'eco-warrior' so I went on EBay and bought some ecoballs (for £10 less than RRP) and some dryer balls.
We tried them for the first time yesterday on 30 degree wash. I am pretty impressed with the results as I was not convinced that they would work. The only stain that didn't come out was the bright orange satsuma juice from all over DS's bobdysuit, but I'm not sure that those would have come out with normal detergent. I decided not to pretreat with the stain remover to give them a proper trial, so maybe if I had, the stain would have faded a bit. Everything else (mixed coloured of mine, DHs and DSs) came out great, even at the low temp.
The dryer balls also seem to work...not need for softener in wash or dryer sheets (which I am v allergic to anyway)and fluffed up towels nicely, bedlinen also tried and came out really soft and nice. Drying time is reduced by about 1/4.
I think it will take a while to get used to the fact that there is no smell to the clothes, but otherwise I am pretty happy with my purchases. They should do me 1000 washes so 2 years worth of washing approx. I should therefore save my money back by not using powder, softener and using less energy to heat the water and less dryer time...
Hope this is not too dull, but I did have a request (sorry, I forget who from) to post when I had tried them out.
