Got a question? Lots of readers do, and chances are pretty good theirs will be yours.

Dear Mary: The rust in our city water leaves an unsightly brown buildup around the rim of my vitreous china sink. I have tried homemade remedies and store-bought products, and nothing has worked to completely get rid of the unsightly stains. Could you recommend something that will help make my sinks look new again? — Diane

Dear Diane: Bar Keepers Friend, available in the household cleanser aisle of most supermarkets and discount stores, will remove those stains without harming the enamel coating on porcelain, known as vitreous china. The active ingredient in Bar Keepers Friend is oxalic acid, an organic acid that works as a bleach and a rust remover. I think you will be amazed by the ability of BKF to remove these stains! Still, it is vitally important that you test any product in an inconspicuous place first to make sure it will not be damaged before proceeding. — Mary

Dear Mary: I currently have an HP printer, which works sufficiently well, but I get so few pages per toner cartridge that I cannot afford to use the printer. I am willing to put the money out for a reasonably priced replacement, provided the toner is more affordable. Suggestions? — Cate

Dear Cate: The Brother HL-L2380DW is a great choice for people who need to print, scan or copy term papers, tax forms, concert tickets and other black-and-white documents. This printer handles automatic two-sided printing. It's pretty speedy, too, at 32 pages per minute, with a cost per page of about 2.3 cents, which includes wear and tear on the drum. This Brother model is quite easy to set up and will be a reliable addition to your home computer network. Expect this printer to work well with any current laptop, desktop, smartphone or tablet, including Chromebooks. The paper tray holds 250 sheets of paper. The printer has a "draft" or "save more" setting that allows you to conserve toner when the document you print does not require professional quality. When professional quality is needed, it outputs sharp black-and-white pages with a resolution up to 2400 by 600. It costs about $129.

If you need a printer to do it all — wireless printing, scanning, copying and faxing — you want a high-quality all-in-one color printer. My pick for the best inexpensive is the HP OfficeJet 8720 All-in-One Printer because it's a workhouse that is not frustrating to use or difficult to set up. Print from anywhere using your smartphone or tablet. This beauty prints and scans two-sided documents in black-and-white or color. The printer has tons of additional capabilities, including Wi-Fi direct (no network required), borderless printing and a legal-size scan bed, to name just a few.

Per-page print costs for the HP OfficeJet 8720 are lower than those of most competing inkjet printers at 1.6 cents per page for black and white and 8.1 cents for color. This is an excellent, affordable, beautifully designed piece of equipment for home or home office. It costs about $200.

Dear Mary: I need a dark-spot corrector for my face. There are so many products out there, most of which are quite costly. If they work, they might be worth it. However, I have yet to find anything that works! — Nellie

Dear Nellie: I have a homemade remedy that's super inexpensive and very effective for most people. But it requires daily diligence: Blend 1 onion in a blender until it is pureed well. Mix with 1 cup of apple cider vinegar (no substitutes, please). Pour this through a small sieve, and place the liquid into a small container that has a lid. Label and store in the refrigerator.

To use: Dip a cotton ball into the mixture and dab onto the brown spots. Leave the mixture on for about 30 minutes. Continue doing this daily (or twice daily if you can manage) for about six weeks to see improvements. — Mary
