The difference between capability and willingness
Almost any provider can put a cleaner in a workshop with a mop. The question is whether they know what goes wrong. Degreaser left on a sealed slab can make it slippery. The wrong pad can burn a showroom floor. Waste from parts washing is not general waste. None of this is exotic, but it is learned rather than guessed, and a provider without the experience will end up discovering it at your expense.
Willingness is not worthless. A capable company with strong supervision can take on a new premises type and manage the learning deliberately, provided they say that is what is happening. The problem is the answer that sounds like experience but is not. Asking for specifics rather than assurances gives an honest provider room to say they would need to check something, which is a better sign than a confident generalisation.
