“Cleanliness is half of faith.” The Quran is more specific and says, “Truly, God loves those who turn unto Him in repentance and loves those who purify themselves.” (Quran 2:222)
I think cleaning should be more important in any religion and civilization. Many diseases can be prevented if a certain level of sanitary is being offered to all of us. The basics are having access to clean and fresh water. Unfortunately this is a luxus most of us don't even value. There are millions of people who don't have access to water on a daily basis.
