Refill pellets for your Ecoballs® that will last for up to 1000 washes. These refills can only be used with Ecoballs®. They should not be used on their own. Ecoballs are a replacement for washing powder in your washing machine. They reduce the amount of detergents entering the liquid waste stream and promote energy savings that help reduce carbon emissions. Not only do they save on heavy shopping loads, they are reusable for up to 1,000 washes. Suitable for temperatures up to 60 degrees. How to fit Open the Ecoballs® units by first removing the sponge ring and the screw from the centre of the unit, then unscrew the two halves of the Ecoballs® units. If the unit is difficult to open tap the rim of the unit against a hard surface and try again. Make sure that the units are tightly put back together after you have refilled them.
