- Moderate Dirt: It excels at removing “green” algae from siding and standard soap scum from shower glass.
- Heavy Buildup: For ancient, mineralized hard water stains or baked-on grease, the scrubber requires a potent chemical cleaner to assist; the motor alone won’t “sand” away years of neglect.
- Brush Selection is Key: Using the soft brush on grout is ineffective; you must switch to the heavy-duty (black) bristle head for noticeable results on porous surfaces.

Can they clean grout effectively?
Yes, but you must use the pointed or heavy-duty bristle attachments. The standard medium brush included in most kits may be too wide for deep grout lines.
