Mask is our small partner in daily life and has the effects of preventing flu, preventing dust, preventing haze, preventing poison and so on. With the development of the times, we wear mask as often as we can, so do you know how to maintain mask? Today let me inform you of the maintenance methods of mask as follows.
First of all, cleaning. Use warm water and soap to slightly knead mask and then use clear water to wash it till clean. Pay attention please and never heavily knead mask because this will damage mask itself.
Secondly, disinfection. Soak clean mask in the 2 % of peracetic acid solution for 30 minutes or boil it in the boiled water for 20 minutes or steam it in a pot for 15 minutes, then dry it in the air for next use. This kind of method is suitable for maintaining gauze mask and bowl shape mask.
Thirdly, checking. Before next use, carefully check whether mask is still good or not and adopt transmittance checking method as well as see whether there are obvious spots or not or something else on mask. If you have questions, this means that you need to change a new mask for next use.
In addition to the all above points, there are also other things worthy of attention when using mask, such as both sides of mask can not be alternately used, mask should be folded and put into a clean envelope if not being used and so on.
