Always get rid of the idea of the private object in this way: assume that it constantly changes, but that you do not notice the change because your memory constantly deceives you. (PI, p.207; see also p.222)
THIS READS as if Wittgenstein conceived the procedure described to be a self-sufficient device for doing this job -- as if it provided all we needed to know or do, to achieve this supposedly desirable purpose. The word 'always' reinforces that impression, making it sound as if the idea of the private object were a well-known psychological nuisance that kept coming back, but could be banished as often as it reappeared, in this simple and effective manner.
Suppose that some people gratefully reported that the technique worked every time, while others said it often works, and some that it never does. Are we misunderstanding the procedure if we are inclined to do a survey on its effectiveness?
The device is not a kind of mumbo-jumbo for disposing of annoying mental states, like getting rid of an evil desire by reciting a psalm. The idea of the private object is not that kind of nuisance. People do not complain of it as they do of headaches or hallucinations.
