Frequently Asked Questions

Can I leave vinegar on my floor grout overnight?

Leaving vinegar on your floor grout for an extended period is not recommended. Vinegar is acidic, and if left sitting for hours, it can begin to break down the integrity of the cement-based grout, making it chalky and prone to crumbling. It is best to limit the dwell time to ten or fifteen minutes before scrubbing and rinsing.

Is apple cider vinegar just as effective as white vinegar for cleaning grout?

White vinegar is the preferred choice for cleaning floors because it lacks the added colors and sugars found in apple cider vinegar, which can leave a sticky residue behind.
