Take every measure to protect your cement tile from stains until it is sealed and waxed.
Accidents happen and the tiles even after sealing may get stained. Stains should be treated as soon as possible. Soda, wine, salad dressings, food spills, etc. should not be left to sit on the tile as they can eventually penetrate through the sealer and stain the tile. Before attempting to remove the stain take time to understand what the stain is.
NOTE: Never use strong acid cleaners on the tiles.

Poultice is a method used to remove stains by reabsorbing the stain using a medium. This is different than just cleaning with an agent. Simply put, poulticing it is soaking the stain out of the tile using a material such as a paper towel or cotton balls in combination with Miracle Sealant Poultice Plus Powder.
Keep in mind that your stain may just be in the sealant if you used a top-coat type sealant. If that is the case, I'd try drugstore Hydrogen Peroxide first. Same stuff as in teeth whiteners. Soak a papertowel and let it sit on the stain. If that doesnt help, try scraping away a bit of the sealant to see if you can just sand or scrape it off along with the stain. Then re-apply sealant to that one tile.
