Scrubbing a turtle’s shell gently with a toothbrush or similar material can be beneficial for your turtle. Scrubbing once a month or as needed will keep the shell free of debris and aid in the peeling process. This may also remove any stuck shed or pieces of peeling shell that has become stuck. Much like brushing your teeth is important, brushing your turtle’s shell regularly (but not too frequently, monthly is fine) will keep it algae and debris-free. This debris usually prevents the scutes from shedding off, so brushing will assist in this process.
