Grout & Tile Cleaning Expert
I’m Jack Martin, the writer and researcher behind Grout Cleaner. I’ve spent 10+ years working hands-on with tile and grout — cleaning it, repairing it, sealing it, and figuring out why some methods work and most don’t.
What I do here: I’ve personally tested more than 500+ grout and tile cleaning products cleaners, sealers, brushes, steam machines, and DIY solutions under real household conditions. Every guide on this site is based on something I’ve actually tried, not repackaged advice from other sites.
Background: Before focusing on grout and tile full-time, I worked in general home maintenance and cleaning, which is where I first ran into the problem every homeowner eventually hits: grout that looks clean for a week, then goes right back to grey. That problem became the reason this site exists.
