I have left some water soluble stabilizer on a project because I did not want someone to feel like it might have been used (and therefore washed). But, I did remove as much as I could and advised the recipient that the stabilizer would desolve when she first washed it.
I would not leave a lot of it on the project because I have observed some of that stabilizer becoming sticky because it got a little damp. I know that some people have said to use a spray bottle on the stabilizer, but I felt like that could increase the posibility of leaving a sticky spot.
You don't say why you would want to leave it on, that may be the bottomline. If it has to stay, then it has to stay.
