Keeping the makeup products neat and clean is essential as you frequently use them on your skin. However, machine washing the makeup bags is something that solely depends on the material of beauty cases. For example, if you have a vinyl or an acrylic beauty case, then their cleaning method would be different. However, if you have cotton or other fabric beauty cases, then you could probably consider washing them in a washing machine. However, it is best to check the fabric instructions before you do that.
