Safe supplies to be chosen over chemical products
White glue, library paste, wheat paste, water based markers, wax crayons
and dustless chalk, liquid water based paints, any water based products.
Do not mix ammonia with chlorine bleach - they will create dangerous
fumes. If you must use ammonia, always have ventilation.
Avoid commercial products. Baking powder, vinegar and lemon are the
best for cleaning. They are friendlier to the skin and more environmentally
safe, and not corporate!
