Photocopy cartridge dropped on your carpets?
First take a deep breath- DON’T PANIC! The most important thing to do is minimise the spread of the ‘black stuff’ (carbon). Use a dust pan and hand broom and lightly sweep as much as you can onto the pan. Vacuum lightly using the hose to directly vacuum, don’t use the head. Now stop. Call your carpet cleaner.
This is one stain that must be treated with the utmost care to prevent spreading or damage to your clothes or skin – Good luck.
