A probe cleaning system and method including multiple pressurized sources and a valve that are configured for cleaning a probe. The valve includes multiple inlet channels, an outlet channel, and a selector. Each inlet channel can be connected to a specified pressurized cleaning source of the multiple pressurized cleaning sources. The plurality of inlet channels are isolated from each other to avoid cross-contamination. The selector can be configured to open a specified inlet channel to pass one specified pressurized cleaning source to the outlet channel at a specified time. The probe can be coupled to the outlet channel of the valve to receive the specified pressurized cleaning source when the specified inlet channel of the valve is opened during a cleaning cycle.
