Fish Window Cleaners Cleaning K Brew in Knoxville TN   Giving to Our Community
In honor of Random Acts of Kindness Day, we wanted to spread some positivity, so we donated a free window cleaning to help a local business in our community! 

We chose K-Brew because we know it's a local favorite and has seen its share of struggles during the pandemic, like many other local restaurants. They are well known in town because they roast their own coffe and bake their own bagels in the store. Be sure to check them out!
