Yes this is true and I suggested this some time ago here in this forum. However don't do this if via the CD test you have established that the material has broken down. If the CD test reveals no breakdown and yet the stickiness is somewhat diminished it simply means the contact surface of the tool has gummed up and has lost its surface tension.
This then can be restored thus:
Run warm water from the tap, add a tiny bit of dishwasher liquid and rub the surface with a finger under the running water until all the soap is washed off. You will know when. Then shake off excess water but do not dry off with a towel or cloth no matter how lint free . Rather let it air dry. Then repeat the CD test. If all is clear you are ready to use it. By the way you will be amazed how much of the stickiness can be restored this way.
Because I have sensitive skin I prefer to use none perfumed "Soap Free" soap called QV Wash a lot. (It is also used in hospitals before surgery). Available from supermarkets. This is particularly suitable for this task.
