Highly recommend Eco Balls, I have the Ecozone ones that I have had for years and just buy refills when necessary. Never had any problems with them. Sometimes, depending on stains you may need to add a bit of the stain stuff that comes with it but I usually rely on the sunshine to get rid of any stains as it it the best stain remover and free!

I don't wash as often as previous post, as I find things still come up clean, but that's my experience of using them. I do add essential oils sometimes depending on what I'm washing

forgot to say - they were £23.99

I have ecoballs.

I love them - washing is mostly clean (not food stains from children though unless it's washed the same day.

I had a problem when I first had them - bumped thread for you.

The key is to wash everyday rather than save until end of the week because marks won't come out after a day or two.

I got mine from the above website as they were the cheapest place I could find.

I have used them for about 6 months now and think they are brilliant. All my washing comes out clean and fresh smelling. I even use them for DS's nappies.

You do need to treat stains such as tomato sauce etc but you'd need to do that before using ordinary washing powder anyway.

I really recommend them.

hi does anyone use theses am really intrested in using these instead of washing powder just wondering how good they are on stains ect and weres the best place to get them thanks
