Will it be unclean? How do I wash it if I wash it myself?
Basically within the body are not very clean, but if you decide to buy second-hand, brought home to their use of disinfectant cleaning, and use special cleaning fluid, after all, you have to direct the water after cleaning up, if you are using a common disinfectant water, if there is residual eating... Don't know whether it is harmful to the body.
No, the money saved will cost you enough to go to the hospital. If you have to go to the hospital, the hospital is very expensive. Besides, it's too dirty and unsanitary!
Try not to buy, second-hand not health. Buy a new is not expensive, the family to buy a little more, office use, you order more water, people will send you!
