Is roller wax hygienic?

[VivaLaDiva]

I was wondering if anyone could help me...I learnt to wax using spatulas, but where I work we use the roller wax system, I find it much easier and less messy, I would like to get one at home, but was just thinking the other day is it hygienic, to roll it on one clients skin, then another? does the heat kill germs? or is there some way of cleaning them?

Hiya, you have to change heads between every client. Remove the wax and sterilise. bye
