Dirty grout in kitchen

About 10 years ago we had Corian counter tops installed and a new tile floor with the grout tinted to match the blue Corian counter tops Now the grout is inbedded with crap and has faded and nothing I use will get it out. I want to clean it all and paint it with acrylic paint we have that also matches the Corian blue, and then put a GOOD SEALER ON. Any ideas for help?
