1. Put the ball in the washing machine with the clothing, and separate white clothes from color clothes.
2. Leave to soak for 30 to 40 minutes; its no necessary to add detergent or softener: the effectiveness of the ball will be not better and could be reduced.
3. If clothing is over 8.5 kg, you can put 2 balls for a better result.
4. Clean spot marks with your usual detergent before putting with the other clothes.
5. Once a month take the ball in the daylight to maintain its effectiveness.
