Grout and tile cleaning and sealing
I need a little advice, please! We had tile floors put down about 4 years ago and they are starting to look kind of dirty. It's mostly the grout, but I think the tile could use a good cleaning too.
I have tried to scrub the grout myself, but didn't notice a big difference. Today I called a grout cleaning company and they charge 375 for a cleaning and sealing. I've heard some not so great things about the company, so I don't think I feel comfortable with that.
Any suggestions? I don't think our tile was ever sealed. Is that a DIY kind of thing or do I need to hire someone? I've heard that steam cleaning tile and grout works. Will any old steam cleaner do?
Any suggestions? Thanks!
