Ceramic tile is beautiful and tough with brilliant colors that last for many years, but, as with many good things, there's a catch. That catch is in the grout lines that aren't as tough and durable, and which get dirty or discolored and hard-to-clean. There are a number of special grout cleaners available at tile and hardware stores. But why pay high prices for special cleaners when a number of common household products work just as well, maybe better, and certainly for less cost? For colored grout, vinegar works wonders -? either applied straight or in a strong solution. On white or light-gray grout, liquid bleach or hydrogen peroxide are the cleaners of choice. Which is better? It depends. Hydrogen peroxide costs just a little more, but it's safer to use and it smells better. You also can gargle with it. But, if bleach is what you have or prefer, use it and enjoy all that cash you'll be saving by not buying expensive specialty cleaners. And that's the On The House tip for today.
