I just wanted to ask, if a piece of clothing becomes najis through ayn ul najasa, and then it is placed into the washing machine, then placed on a drying rack, is the drying rack considered najis too? I rewashed the clothes in the washing machine on a rinse cycle, which according to the manual rinses the clothes 3 times, with an intermediate spin setting. would that suffice to purify the clothes and in the case if wringing were required?

The washing machine, if it is connected to running water should purify it. As long as you rinse it, which the washing machine does, it becomes tahir
