The mechanism of action of the cleaning agent is very important in the event of hard, high-temperature contamination. Poor decision-making and not having the right people involved can delay an oil flush longer than any of the items listed above. Over time, however, harmful deposits and sludge may have accumulated, causing power and performance loss. The main root causes of high-temperature contamination are engine load (high oil temperature tends towards oxidation; a large load also leads to higher production of particulate matter, which contaminates the oil) and long oil change intervals or an absence of oil changes. Cleanliness certificates should not be considered valid if the cleaning has not been performed to these requirements.

Over the past several years, extensive resources have been used to improve flushing techniques for hydraulic and lubrication systems. Despite the efforts, there is probably no area relating to hydraulic and lube oil systems with a wider deviation between theory and practice. In essence, there are many times that we do need a turbine flush but we must be careful in selecting the type of flush that is ideally suited for our system and its conditions. Once the initial 24-hour flush is completed, the inspection media should be inserted at the farthest point from the filter. Special flanges, manifolds and connectors may be needed to assemble the components to be cleaned in series.The non-detergent flushing oil would be for any engines or machinery with any phosphorus, bronze bearings or parts(white metals). The cheapest method would be to just use a garden hose to inject water into the fill hole, and flush everything out. Inspect the drained oil and drain ports for contamination that may indicate the need for power flushing or wand flushing. I'm no expert on how to get rid of carbon but I'd have thought a flush wouldn't shift much, especially if it's blocking oil ways going to bearing surfaces, carbon won't shift past there in a hurry. Realizing that most commissioning groups and maintenance personnel are not oil flushing experts is the first step.

The oil won’t last as long or protect as well if it must contend with sludge and deposits from the previous oil.

These standards should be used as the minimum criteria, but it is always best to customize your plan for the individual system using the manufacturer's recommended specifications. This product can also be used if the service fill lubricant has to be drained because of a contamination problem. In these cases, the combination of oil and sludge is almost acting as a sealant, essentially keeping them viable and masking their true condition. With remnants of varnish and sludge in the system, these can negatively impact other properties of the oil such as acidity, water separability, foam inhibition and Membrane Patch Calorimetry.

I know that the heavier deposits don't actually drain away completely, they're too heavy and just sit at the bottom and don't budge. Once you understand the problem within the machine that needs to be cleaned, you can then select the appropriate flushing tactic to remedy it. This can lead to a lot of confusion, as the system will appear clean as you flush it, but then starting and stopping the pump will free debris and send it into your inspection media.
