It's so easily done, you've tiled the wall perfectly, just finished off the final grouting and the door bell goes or the phone rings!

When you eventually return to your handywork the excess grouting has all dried. Don't despair, there's no need to use a scraper which could damage your tiles. Just use some cotton balls dipped in nail varnish remover. This immediately disolves the excess grout. Once the offending grout has been removed wash down with soap and water and polish, to a perfect finish.
