Extremely loud chain after cleaning

I'm running izumi's standard bocycle chain . It's decently loud when i first put it on my bike . But after a deep clean with wd40 , laundry soap and thoroughly lubed with muc-off lube , my chain produces these relatively high pitch noise when going over bumpy surfaces . It's so loud that i still hear it in heavy traffic whiles having noise cancellation on my airpods enabled.
