| Can I turn the bottle upside down? |
Sure! The possibility to spray at all angles is one of the major advantages of Bag-on-Valve. |

| Is the system heat/cold resistent? |
The Bag-on-Valve aerosol generally stands heat and cold very well, but tests must be conducted on each individual product. |
| What about recycling? |
What recycling system to be used varies from country to country.The Bag-on-Valve system contains no flammable propellants, but a minor pressure remains in the can after emptying. |
