Yes, for my birthday in June, I held fast to my pledge to not add any stuff to my house this year - only buying food and experiences! So I told my husband what I wanted was the grime removed. We just had our grout cleaned and resealed. First time in 16 years that someone besides myself cleaned the floor! I don't know if you can tell from the pictures, but it is so nice - like brand new! It wasn't cheap but totally worth it!
Before - with tape marks from rug tape
Before - more tape marks from run tape
Pretty happy with the result! I may never scrub floors again! :)
