Keep the good hygiene with onahole cleaner. It has scent of citrus. Use only few drops for one time.
(First liquid based cleaner i've bought so my insight is limited and another cleaner may be far better)
This product is pretty invaluable for keeping your onaholes clean i might have to wash it out a few times to get it all out but it's worth it.
I have had this for a few months now and using it frequently i've only used 1/3rd of it.
As for the product itself, it doesn't seem to leave a smell(that i've noticed at least) my onaholes seem pretty clean and with this product i'm confident in finishing inside them as it's pretty decent at doing it's job.
I originally had a far better review typed out but the website needed me to relog so i had to quickly type out this one, i would recommend this to anyone owns an onahole as i said in the summary, it's essential.
