Fish Window Cleaning & Claymont Steak Shop   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 two local businesses in our community! 

We chose Claymont Steak Shop and Bing's Bake & Brew because we know they're local favorites and, like many other local restaurants, have seen their share of struggles during the pandemic. 

Our goal is to help make lives a little brighter and we're happy to give to our community!
