In the long list of places we all dread cleaning, scrubbing dirty grout lines in the bathroom likely ranks near the top. Battling gross grout with an old toothbrush and mildew remover always takes longer than you'd expect—and once you think you're done, all of that hard work seems to magically disappear a few showers later. To make your efforts last longer, the next time you finish a serious grout scrubbing, seal it off with an under-$10 grout pen.

What's a grout pen, and why haven't I heard of this sooner, you ask? It's an ink formula in a pen form that you draw over stained (but cleaned) grout lines to give them a fresh white (or gray, or whatever color your grout is) appearance. It's almost as easy as it sounds, but it will take some patience and precision to carefully paint within the lines. Accidentally getting some of the ink on the tile surface will give away your secret trick immediately, so applying the formula carefully is crucial for the finished effect. But if the Instagram evidence below is any proof, taking the time to refresh your grout carefully pays off. And while this trick certainly won't last as long as re-grouting and won't withstand harsh tile cleansers, it's an affordable quick fix perfect for renters or homeowners who want a temporary solution before they commit to a complete grout overhaul.

Miraculous grout pens don't just work on white grout. Instagrammer @_houseofkate proves that a gray grout pen can completely update the look of a tiled shower stall.
