2 reviews for 2.5g NaDCC Chlorine Tablets – 200 per tamper evident tub

  1. nick (verified owner)

    Excellent product. Use it for all sorts of things – disinfecting washing machine – just add a tablet set to rinse/spin. Beer making – sterlise equipment. Surface cleaning – add to 1 to spray bottle.
    Disinfecting clothing – add 1 tab to wash and rinse well. Disinfect dish cloths/sponges.brushes Disinfect salads (see label for dosing). Much better than household bleach as it is non-caustic, food safe (in recommended doses) and does not rot fabrics and is generally much safer. Also stores for months (years ?) in cool dry place in tablet form. I have been using this product for several years. Excellent and prompt delivery.
