Sample Project: Make and Use a Citrus Classroom Cleaner 1. Tear the peel from one orange and put it into any jar (like a clean peanut butter jar). 3. Pour a few ounces of this concentrated cleaner into a small pail or a spray bottle filled with water (this cleaner will kill germs but is non-toxic for our air and water). 4. Use it to clean any hard surface at school: desks, sinks, counters, etc. (Do not use on natural stone.) |
