Hi, I would feel totally comfortable using Burt's Bees products, as they are safe and made from natural ingredients. They sell skin care products, for people, and babies, which are safe and gentle, and I myself use their lip balm, and I love it.
Many members on here use witch hazel on their bullies to cleanse the skin, and to clean and dry out the ears and it is safe to use, also peppermint oil is also a natural ingredient, and is also a drying agent, so I would think this would be safe to use as well. My vet gave us a ear cleaning solution for Dozers ears, which works the same way, by drying out and cleaning the ear canal. I always like to use natural products when able to, so the Burt's Bees cleaner is something I would definetely try, and be comfortable using. Having said that the ear cleaning products are meant to be used once a month, or every two months for cleaning the ears, you don't want to over use these products. There are other preventative things you can do to keep the ears clean, and to avoid infections. We use sensitive skin, unscented baby wipes on our bullies to clean their faces, nose ropes, and to clean the excess wax and buildup on the skin inside of their ears, this helps keep them cleaner in between their baths, and monthly ear cleanings. You can avoid a lot of ear infections by being careful when you bathe them, by not letting water get in their ears, or if they swim in lakes or pools, making sure the ears are dried out after swimming, and not letting the water stay in the ear canal. Also something my vet told me after Blossom had her cherry eye surgeries, and I had never thought about, is not letting them stick their head out the window when driving in the car, as the wind will irritate, and dry out eyes, which is not good for cherry eye, but also the wind is not good for their ears either, and could cause ear infections as well.
