Pressurized cleaning system

A washing system, comprising:

• a vessel with an inside for storing a cleaning solution, the vessel including,
• an inlet connection point, in gas communication with the inside of the vessel, for pressurizing the vessel;
• an outlet connection point, in fluid communication with the inside of the vessel, for dispensing the cleaning solution;
• a relief valve, in gas communication with the inside of the vessel, that is configured to remain closed when pressure inside the vessel is below a predetermined value and automatically open when pressure inside the vessel exceeds the predetermined value;
• and
• a purge valve, separate from the inlet connection point and the relief valve, that is in gas communication with the inside of the vessel and that is configured to enable a user to open the purge valve and allow gas in the inside of the vessel to escape.
