I've had a transparent onahole for 5-6 years and despite not using it that much, it yellowed over the years.
I've bought a UV cleaning box over amazon.

Does the H2O2 / UV trick work on the kind of plastic they're made from and if so, how do I proceed?
>Put it in a freezing bag with a solution of water/h2o2
>Put h2o2 in it, seal the hole and wait
>Put the box on a heater during the process
