Caution: Take care when using this fibre on Perspex or Plexiglass screens especially in hard water areas – this can lead to fine calcium deposits which have a sandpaper effect on the surface and can leave scratch-marks on the surface. In this case treat area with Calcium Dissolver beforehand (1 teaspoon per litre of water), rinse with water and dry using this fibre.
- If cleaning with the white fibre is not enough (in very hard water areas), or when using this fibre for the first time, use the following procedure:
Mix 1 teaspoon of Calcium Dissolver with 1 litre of water and wipe over the areas with the white fibre. Rinse with lots of water and dry off with the fibre.
- In extreme cases diluted Calcium Dissolver can be left on the surfaces for a period of time to take effect. If necessary repeat the procedure.
- Use DAMP to WET.
