For sticky stuff, try soap and water first

Q Decorative stickers were applied to walls freshly painted with latex paint. Now, when I try to remove them, they leave a sticky residue. I have tried soap and water with no luck and "Goo Gone," which removes the residue but leaves a stain. Do you have any suggestions?

A Washing the Goo Gone stain (basically an oil stain) with soap and water should remove it.

Generally, to remove sticky residue from decorative stickers or from price tags try the following:

• Soap and water (let it set on the residue for a couple of minutes before scrubbing to remove.

• Rubbing alcohol

• Baby wipes

• Goo Gone, or WD-40. May remove the residue but leave a greasy stain, which can usually be removed with soap and water.

Always pretest in an inconspicuous area first.

Passport needed? Q Should I carry my passport with me when taking domestic flights?

A It's not necessary. To take a commercial flight, TSA requires a government-issued photo ID and a boarding pass, said Carrie Harmon, a Department of Homeland Security spokeswoman. A state-issued driver's license, a military ID or passport are three examples of permissible IDs.

Unless you want to use your passport as your photo ID, you don't need to carry it on domestic flights, Harmon said. Most passengers use their driver's license.

Sweeter out of the cold Q Is it true that fruit at room temperature tastes sweeter than out of the refrigerator?

Warming the fruit or the food will increase the flavor potential of many of the acids, esters and aldehydes in the product. If they are pleasant tasting, the food might seem sweeter. However, if they are unpleasant, the food might seem more acid or bitter.

Many bitter molecules are less bitter when cold. Coffee, for example, is most bitter at room temperature and least bitter when served iced or hot. Melted ice cream tastes almost sickeningly sweet, while the frozen ice cream tastes just right.
