We've been doing spring cleaning at the gym and I learned a very important lesson today. . . Be careful when cleaning with ammonia! I was instructed to fill up a bucket with water and add some industrial strength disinfectant whose active ingredient is ammonia. Well I scrubed things down around the gym for a little over two hours, gloveless. My hands have felt tingly, hot, and cold all at the same time for the rest of the day! It's really bothersome and I'm hoping it will go away tomorrow and that I didn't do any permanent damage. Lesson learned...don't clean! ;) j/k Just wear gloves!
