Was watching an episode of Wheeler Dealers (only car show I can stomach) Ed China was cleaning up bits and pieces of gearbox & engine... he used a trigger spray with a degreaser fluid. There was no rinsing off .. but unsure if this was a solvent based product or water based. Anybody recommend a good degreaser ... for mechanical parts. I have seen this on screwfix .. https://www.screwfix.com/p/no-nonsense-heavy-duty-degreaser-5ltr/88668?_requestid=444519 Anybody used, or know of something better. Appreciate you might want to rinse off BBQ parts or floors, but for mechanical parts no need to rinse is preferable.
