Did you know your smartphone is a breeding ground for germs? Think about it: Your phone goes just about everywhere with you (grocery shopping, work, the park...the bathroom), which means there are plenty of opportunities for exposure to bacteria. In fact, a study by the University of Arizona found that the average cellphone has more germs than a toilet seat—10 times more, to be exact.

Follow these steps for deep cleaning your smartphone, and tips for keeping it germ free.

Before you begin to deep clean your smartphone, it's important to remember these tips:

"You'll also want to use a microfiber cloth, which is surface safe, instead of paper towels," says Rob Duve, a Best Buy Geek Squad agent. "If you have a spray cleaner, don't spray it directly on the screen. Spray it onto the cloth first, and then wipe down your phone."

Because microfiber can remove bacteria from a surface, you can play it safe by skipping the spray cleaners altogether.

Follow these steps to thoroughly clean your device and its case.

After unplugging and turning off your phone, gently wipe the outside of the phone and the screen with a fast-drying bleach-free disinfecting wipe. Alternatively, spray 70% isopropyl alcohol onto a clean microfiber cloth and wipe your phone.

Do not spray any cleaners directly onto the phone's surface, and avoid getting liquid in the charging ports.

If you have a case on your phone, remove it and gently wash it with mild dish soap and warm water. Be sure to clean the crevices and edges, as they tend to collect dust and dirt. Let it air-dry completely before putting it back on your phone. Remember, no moisture should get on the phone's openings and charging port.

Experts recommend cleaning your smartphone daily (at least), says the FCC. This helps prevent dirt and grime buildup and can keep your phone germ-free. Of course, if your phone was in a dirty spot or you feel it needs a quick wipe down, cleaning it on the spot or more than once a day is a good idea.

In addition to wiping down and deep cleaning your smartphone periodically, the following advice helps keep it clean longer and between cleanings.

After going out in public areas, try your best not to use your phone until you've had a chance to sanitize or wash your hands. "One of the first and best lines of defense is to practice good hand hygiene. Always wash your hands with soap and water because anything that is on your hands will be transferred to your cellphone," says Duve. "Be cautious when using other people's devices, too. If you do have to use someone else's phone, avoid holding it up to your face."

Be mindful of where you use your phone. More people than you think bring their smartphone into the bathroom, exposing them to unnecessary germs. While it may be tempting to bring your phone with you everywhere, be selective to reduce bacteria exposure.

Keep your smartphone in your pocket, bag, or car when not at home. This helps minimize airborne bacteria.

Avoid touching the phone's screen to your face by using earbuds or other hands-free device to make calls. That way, you avoid spreading germs from your phone onto your skin and vice versa.

Using 70% isopropyl alcohol (or wipes with this amount) is safe for your cellphone. However, avoid rubbing alcohol as it can strip your phone's protective coating.

It's important to stick with alcohol-based products. Do not use Windex, Clorox, or Lysol cleaners on your phone, as they can contain other abrasive ingredients.

While you want to sanitize your hands before handling your cell phone, do not use hand sanitizer directly on your phone's screen or surface.
