It's likely that mineral build up is causing this. Put some white vinegar in the reservoir with your water.Allow it to sit a bit, working the trigger. Then put your mop in the bath tub or somewhere that you can allow it to steam without concern. Steam the entire contents of vinegar/water through. The vinegar should clear out the mineral deposits.
