Hand scrubbing the adhering soil with a scrub brush and/or toothbrush while washing is necessary to remove sticky soil.
A pressurized washing system is often necessary for effective cleaning (e.g., Hydroshot portable power cleaner with 30 or 45° nozzle, stainless steel keg with air compressor and pressure washer gun).
It is extremely important to ensure that the membrane, plastic casing and any cracks are absolutely clean because any contamination with soil will alter the results.
