Scrubber leaving streaks on painted concrete floor
I am experiencing problems when scrubbing a painted concrete floor. Does anyone have any ideas on how to overcome this?
I scrub a painted concrete floor in a retail trade shop once a month. I use a machine to scrub the floor with water only. The scrubber has a squeegee and a vacuum to remove the dirty water.
When I empty the dirty water from the machine it is almost black! The floor looks OK before scrubbing but it really is dirty. Last night I wet a cloth and wiped the floor and the cloth was black. So the floor does have a lot of dirt.
Before scrubbing I dry mop the floor to remove any debris. Then I scrub moving up and down the isles. When I have finished, there seems to be a white film or white streaks along the floor.
I have tried following the scrubber with a mop and that seems to help a little but it still leaves streaks.
The scrubber works very well on other jobs (e.g. tiled floors) with no such problem. The scrubber is cleaned thoroughly before each job.
I have considered that perhaps we need to scrub more frequently or use a different machine (e.g. one with rollers rather than the rotary scrubber).
Any ideas will be appreciated.
