The results are truly amazing, we have cleaned grout in restaurants that was literally black that has come up like new. You will be amazed. The one concern with extremely soiled grout is that the soiling can cover up permanent staining, that you may not have been aware of. Cleaning may reveal these types stains.
Cracked grout is damaged grout but it can still be cleaned. Be aware that due to the cracking it has the potential to crack further and possibly break right out. We will be extra gentle with our cleaning but the potential for further damage to your grout exists. Extensive missing grout should be re-grouted.
Good question. Staining around toilets is difficult to completely remove as the staining usually has gone very deep in the grout itself. So to answer the question this type of staining is usually fairly permanent, if the stain is fairly fresh and the grout has been sealed more of the discolouration will be removed. The longer you leave it unclean and not sealed the worse it will get. It is recommended to have it cleaned even if the results are not as spectacular as in a typical kitchen.
