Don’t push the toothpick too far into the microphone. It may be helpful to start at an angle. Insert the point so it’s just past the inner rim of the opening but not farther. You can puncture the microphone if you jam it in down the center. You’ll feel it pop if you’ve gone too far. Make small, gentle movements and go slowly. [1] X Research source

Never blow the air directly into the hole as that can damage your phone. Aim the blast at an angle parallel to the microphone for best results. [4] X Research source

Do not allow the slime to sit for more than a couple seconds or it can begin to ooze and ruin the device.

In a paper cup, dissolve the borax in 8 ounces of warm water. Set aside. In a separate bowl, combine remaining water and school glue. Mix well. Add the borax water mixture and stir together until firm. Knead the substance for about 5 minutes or until it forms into a dry ball of ooze. Use your homemade cleaning putty as you would store bought. If the putty will not form into a ball do not use as a cleaner. Try adding more borax until it reaches the right consistency.
