How do I deep clean and reseal saltillo tile floors?

I live in a 30+ year old home that has Saltillo tiles in the kitchen. They are stained and needs resealing. We recently tiled the remainder of the house and there is a big difference in the two colors even though I know they are the same tiles. I think that if I can deep clean the old tiles and then seal the entire house with a darker colored sealant it will bring it all together. HELP!
q how is the best way to deep clean and reseal saltillo tile floors
