Getting out that damned spot with new iPhone app from Tide

Now there's an iPhone/iPod Touch app for just about every stain.

The new Tide Stain Brain app from Proctor & Gamble, one of the latest home-related iPhone/iPodTouch applications, allows you to find and share stain-fighting solutions for all kinds of messes. If you don't have an iPhone or iPod Touch, you can access the information on the Tide Web site.

No surprise, but the free app takes every opportunity to push Tide laundry products. For example, the first action recommended for common stains like chocolate, dirt, and grass is to "Try Tide Stain Release. Just add it to your wash along with your regular detergent." But other advice is more generic, plus the app and Web interfaces allow you to vote on the stain-fighting solution. For instance, as of late last week, 54 users gave Tide's blood-removal treatment a thumbs down, compared with 35 who approved. You can also submit your own remedies.

No matter the source of the mess, use these general stain-fighting tips:

Act fast. Quick treatment is often the key to stain removal.

Blot, don't scrub. Scrubbing can damage fabrics. Instead, blot with a paper towel or clean cloth. Gently scrape semisolid fabrics with the edge of rounded spoon.

Do a colorfastness test. When using a recommended cleaning agent, always pretest it in an inconspicuous area, such as the back of a tie or an inside seam.

Be patient. It could takes several passes to remove a stain. Always start with the mildest option before moving on to more-aggressive cleaning agents.—Daniel DiClerico | e-mail | Twitter | Forums | Facebook
