It's time to reach into the inbox and pull out a few questions from my loyal readers, the answers to which I suspect might be of interest to others. I love receiving your questions, by the way, so keep them coming!

Dear Mary: What is tamari? It is an ingredient in a recipe for Spiced Hazelnuts I would like to make. Where can I find it? — Catherine

Dear Catherine: Tamari is a type of soy sauce, usually used in Japanese food and nearly always gluten-free. In a pinch, you can easily substitute with Chinese light soy or regular Japanese soy sauce. You should be able to find tamari in the Asian section of a good supermarket, or for sure in a Japanese food store.

Dear Mary: Could you please tell me where I can purchase Glisten Dishwasher Cleaner and Hard Water Spot Remover? I used to get it at the grocery store, but it's not carried any longer. It is really wonderful for cleaning my glassware and stainless steel dishwasher. — Peggy

Dear Peggy: Your favorite Glisten Dishwasher Cleaner and Hard Water Spot Remover are available on Amazon at about $7 for two single-use packets. However, you might want to consider a cheaper alternative that gets even higher raves and reviews: Lemi Shine Appliance Cleaner, which is multipurpose and comes with three single-use packets for about the same price and a more far-reaching availability. Both products produce excellent results.

Dear Mary: I have four bottles of sunscreen that have expired. I know that they have lost their full effectiveness as sunscreen, but is there another use? I hate to throw them out. — Dorothy

Dear Dorothy: Great question! And good for you for realizing that sunscreen does expire (a good reason to not buy the big economy size unless you are a real sun worshipper). Dr. Karen Burke, a dermatologist and research scientist on the dermatology faculty at Mt. Sinai Medical Center, tells us that all sunscreens have an expiration date printed on the label. Typically, they last a year or two, and most are good for three years.

The safest bet is to throw out the old product and replace it. But in a pinch, here's a secret: Dr. Burke says that sunscreen is still good for six months after its expiration date. During that period, it's better than nothing.

After that, if your sunscreen has a moisturizing component (most do), you could use it for hand lotion. Sunscreen also makes a dandy shaving cream, expired or not. Just make sure you mark these bottles clearly as expired so you don't accidentally use them next summer, or you could end up with a nasty sunburn.

Dear Mary: How can I remove a very stubborn ring in my toilet? I've tried several things, but nothing seems to work. I read your column every day. You do help a lot of people. Thank you. — Anna

Dear Anna: That stubborn ring is likely caused by minerals in hard water that have built up over time. The best way I know to get rid of that ring is to don a pair of rubber gloves and go after it with a pumice stone like the Pumie Toilet Bowl Ring Remover, available in home improvement or drug stores, or online. Surprisingly, pumice will not scratch the enamel finish of a porcelain toilet. Use the pumice stone as you would a sponge. Many thanks for your kind words.
