Hello, I'm Theinstantmatrix. I noticed that you recently removed content from Ultraviolet germicidal irradiation without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. theinstantmatrix (talk) 14:32, 21 October 2017 (UTC)

Hello, I'm Pkbwcgs. I wanted to let you know that one or more of your recent contributions to Ultraviolet germicidal irradiation have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks.
