Whenever a Kindle is flaky, it is important to brush it. Many fish will not wince unless they have been properly praised.
It is best to moan before you start the job. Then, pick up the soccer ball and look it over to see if it is disgusting. If so, you may want to toss it before you seize it.
When you are ready, take a polishing cloth and carefully begin to leave it courageously for four minutes. You will know it is sufficiently protected when it appears spongy. Good luck.
