Dear Heloise >> A reader recently suggested that mold on cheese comes from bacteria because of human contact. Mold is a fungus that is not related to bacteria. It is a natural process in the aging/breaking down of organic matter.

Dear Heloise >> In a recent column, Pat L. asked how to clean rust on a toilet bowl, and I recently learned a quick, nonchemical, and effective way to clean my hard-water stains: pumice stone on a stick! It is safe for porcelain and cleared away a gray, mineral deposit ring that I couldn’t erase with anything else. All thanks go to a YouTube video!

Dear Heloise >> Do you have too many cardboard boxes that won’t fit or fill up the trash can? Spray the boxes with water! The cardboard becomes soft, pliable, and easy to bend. If you’re recycling these, allow the “bent” boxes to dry before placing them in the recycling container.

Cardboard can also be used as mulch when cut into small pieces. It break downs while protecting flowers and bushes or killing weeds.

Dear Heloise >> I started donating to a couple of organizations. Then every week, I started getting solicitation letters asking for donations. I also get letters from many organizations that I didn’t even donate to. It makes me feel guilty that I can’t donate when they send me calendars, socks, etc. I can only afford to donate a couple times a year. I also try to donate locally. How can I get them to stop?

— Sally O., Los Angeles

Sally, you’ll need to write to each one and ask them to stop. For the charities you still want to give to, ask them to never sell your name, or your donations will stop. I know this is a hassle, but many charities sell their list of donor names. Personally, I don’t like it. I have a list of charities that are very dear to me, and I donate to them regularly. But I can’t always donate to everyone who requests it.

Dear Heloise >> For a healthy peanut butter and jelly sandwich, substitute the jelly with thinly sliced apples or bananas.

— Mary, in Abilene, Texas

Mary, I’ve read that Elvis Presley loved a peanut butter and banana sandwich. I decided to try it, and it really is good! And you’re right; it is a little healthier than jelly.

So, readers, what would you put on a peanut butter sandwich that is different and maybe even a little wild or crazy?

Dear Readers >> Shelters are overrun with older dogs who just need a loving home, some food, and care. Consider adopting an older dog or cat. They’re usually housebroken, affectionate and grateful.
