We recently completed a renovation that included white tile/grout. When we moved back in, the grout was already dirty because the contractor did not cover the floor after finishing it. I didn’t think it was a big deal since I have cleaned a lot of grout in the past. However, no matter what I try, I can’t get the grout clean. I regularly use my steamer and grout brush to no avail. The contractor used Bostik Hydroment Vivid grout. He is offering to either reseal the grout if we can get it to a level of clean we find acceptable or to “paint” the grout with Polyblend Grout Renew.

Does anyone with knowledge of these products have a suggestion? If we go the Polyblend route, will I be able to steam clean the floor? Thanks in advance for your input.
