We use 2 words when it comes to cleanliness in Hinduism. They are "Shuchi" and "Shubratha". "Shubratha" can be described as neatness / cleanliness if you consider its usage in other Indian languages. Then what does "Shuchi" mean? I don't think it also means cleanliness.
I can give you a reference for the usage of "Shuchi" in phalashruthi of Sri Sukham as below:
Yah Shucih Prayato Bhuutvaa Juhu-Yaad-Aajyam-Anvaham ।
Suuktam Pancadasharcam Ca Shriikaamah Satatam Japet ॥16॥
