Parts and contaminants · 3 min readRemoving carbon deposits from engine valvesIntake valves on direct-injection petrol engines and exhaust valves on every engine carry hard carbon on the tulip and stem. How to clean valves once the head is off, keep each valve with its guide, and tell a cleaned valve that can be refaced from one that is scrap.

Parts and contaminants · 3 min readCleaning food industry filters with ultrasoundSieves, strainers, sifter screens, fryer filters, filter candles and centrifuge screens clog with fat, protein, pulp, starch and carbonised oil. Which food filters can be cleaned and reused, the chemistry for each soil, why the reverse flush matters, and the hygiene steps before a filter goes back into the line.

Parts and contaminants · 3 min readCleaning bakery equipment with ultrasoundBaking tins and trays, depositor nozzles and pistons, divider parts, slicer blades and cutters carry dough, sugar, fat and carbonised release agent. What ultrasonic cleaning removes in a bakery, what it cannot remove without harsh chemistry, and how to treat coated tins so the coating survives.

Parts and contaminants · 3 min readUltrasonic cleaning of turbocharger componentsCoked oil in the bearing housing, soot in the turbine housing, sticking vanes in a variable-geometry ring, oil film on the compressor side. How a turbo rebuilder strips and cleans each part, which metals need which bath, and what gets replaced rather than cleaned.

Parts and contaminants · 3 min readUltrasonic cleaning of cylinder heads for automotive repairCarbon in the chambers and ports, oil sludge under the cam covers, scale in the water jacket, gasket remains on the deck. How a head is stripped, which bath suits aluminium and which suits cast iron, and where cleaning sits between crack testing and valve-seat work.

Parts and contaminants · 4 min readCleaning EGR valves in an ultrasonic tankSoot and oil mist bake into a hard cake in the EGR valve and its passages. How to remove the bulk, protect the actuator, which liquid and temperature break the rest, and how to tell a cleaned valve from one that needs replacing.

Parts and contaminants · 4 min readHow to clean petrol fuel injectors with ultrasoundPort and direct injectors clog at the filter basket and the nozzle. What an ultrasonic bath cleans, why the injector has to be pulsed for the inside, which parts come off first, and the flow test that proves the result.

Parts and contaminants · 3 min readUltrasonic cleaning of diesel injectors in the workshopCarbon at the nozzle, tar from blow-by on the body, lacquer inside. How common-rail injectors are prepared, which parts go in the bath and which never do, the liquid, temperature and time, and why the test bench has the last word.

Parts and contaminants · 4 min readUltrasonic cleaning of carburettors: the complete processVarnish, gum and carbon out of jets, emulsion tubes and drillings without hours of wire and spray can. Strip-down, liquid, temperature, frequency and time for aluminium and zinc bodies, and what must never go in the bath.

Process and parameters · 4 min readCleaning liquids for ultrasonic cleaningWater with a detergent does most jobs. Which chemistry for oil, carbon, oxide and flux, what never goes in the tank, and why concentration and temperature matter as much as the product.

Parts and contaminants · 4 min readRemoving carbon deposits and baked-on oilCarbon on pistons, valves, injectors, turbo housings and EGR valves is oil that has been cooked onto the metal. It needs the hot end of the bath, the strong end of the chemistry, 28 kHz, and time. What works, what does not, and how to avoid damaging aluminium in the process.

Industries · 5 min readUltrasonic cleaning in the aerospace industryEngine parts, avionics, interiors, composites and precision instruments: the contaminants of aerospace maintenance and how ultrasonic cleaning deals with them.

Industries · 4 min readUltrasonic cleaning in the automotive industryEngine and transmission parts, carburettors and injectors, brake calipers, bearings: what contaminates them, what ultrasonic cleaning removes, and where the traditional methods fall short.

Parts and contaminants · 2 min readUltrasonic cleaning for automotive parts: what it does wellCarbon, grease and road dirt off engine parts without hand scrubbing: where ultrasonic cleaning earns its place in a workshop.
