What use are beautiful tiles when the joints are dirty and beyond the help of traditional cleaning methods? We were wondering the same thing which is why we developed the edding 8200 grout marker. You can use the grout marker quickly and effectively in the bathroom or kitchen to restore the shine of your grouting. It’s very easy to use: simply shake the pen a few times, open it and place the nib on a piece of cardboard. Carefully pump it up and down until ink flows into the nib and your grouting will be as good as new! The 2–4 mm wide bullet nib is perfect for normal joint widths. This invaluable DIY pen is available in white or silver-grey and comes with three replacement nibs.
