A wellbore system includes a logging tool operable for taking measurements in a wellbore and a spinner flow meter carried by the logging tool. The spinner flow meter is operable for determining a local speed of a fluid impinging upon an impeller of the spinner flow meter. The wellbore system also further includes a fluid source including a solvent for inhibiting the adherence of a sludge on the logging tool. A pump is in fluid communication with the fluid source and is operable to impart a hydraulic pressure to the solvent. At least one hydraulic nozzle is carried by the logging tool, and the at least one hydraulic nozzle is directed at the impeller of the spinner flow meter and is in fluid communication with the pump. A controller is operably coupled to the pump to selectively deliver the solvent to the at least one hydraulic nozzle.
