my doctor did not mention that to me so i have been cleaning using my regular soap free feminine wash. so far there are no issues.
pls dont NOT wash it. wash it with water is fine, you can also try cetaphil or those kind of soap which is similar to it
Been using my feminine wash even when preg, no problems at all
