Here’s how to FIX the clumping brush issue!!
This definitely works! Night-&-day difference within 4-5 days for me and my teeth have never been whiter (honestly!)
CLUMPING BRUSH ISSUE — I found this to be troublesome after the very 1st night of use, but getting a bit of rubbing alcohol onto a paper towel and cleaning the bristles made it like new again each night; ready for the next day.
