Clean Cloth Nappies review

  • Admin conditions: Front Loader washing machine, water hardness- 90ppm mg/L, heavily soiled laundry
  • Fragrance: Moderate in strength
  • Stain removal power: Great – Good
    Required some additional stain removal methods.
  • Value for money: Good – Ok
    UK powder detergents often include a significant amount of water softener because of how varied the water quality throughout the UK is. In some parts of the UK the water can be very hard, 300ppm/ mg/L + in many areas. Because of this a lot of detergent is needed (and/or the addition of water softeners such as sodium carbonate, or laundry booster/ stain remover powders). For water quality- 90ppm mg/L the amount required was reasonable, but for harder water, a lot more would be needed. For those situations, it would be economical to include sodium carbonate or a laundry booster/ stain remover or some cheaper detergent,  in addition to Persil. 
  • Whites and nappies:
    Pre wash: 50g = 70ml
    Main wash: 150g = 175ml, increase or decrease as required.
    If you are still experiencing stains, add a stain remover. Either laundry booster/ stain remover powder or chlorine bleach as per the Chlorine Bleach calculator to the cycle.
  • Darks and colours:

Final assessment: I would definitely use this again.

Overall the stain removal ability was good, I added 30ml of Vanish because of food stains such as tomato and strawberry which are difficult to remove without additional stain removal assistance. Any remaining food stains after the wash were then removed using the Chlorine Bleach calculator.

To be noted: Some admin have had success with this detergent in the past, and some have not.
