Can I wash my heavy wool talis together with the silver Atora,what happens if I won’t remove the Atora? I will appreciate if anyone can assist me,thank you!
I don't know where you live. In Brooklyn, Lakewood and other areas where there is a large Jewish population, the dry cleaners will take off the Atara, clean the Talis, reconnect the Atara and your Talis and Atara will look sparkling clean.
I do not think it is a good idea to put an Atara in the washing machine.
You can also contact Mefoar Judaica and they offer cleaning and shipping for an Atara.
If you are willing to go the dry cleaning route where they remove the atarah and reattach it, that's the best way to go but it will cost.
If you are on a low budget, check the two answers how to wash it by hand but keep in mind that you will need to be prepared to properly iron it as otherwise it might look like "you slept in it" sort of look. This is not as easy as it sounds as wool is sometimes hard to iron because it can be easy to make creases in the wrong places. Also, it's very big and hard to manage on a typical ironing board.
If you want to use a washing machine, put it in a pillowcase or some protective washable material, use a wool cycle which is usually very gentile and uses a lot of water and little agitation (vs. a regular cycle) and take it out of the machine after a couple of revolutions in the spin/rinse cycle so most of the water is extracted but the atarah is not abused. Be prepared to be near the washing machine to be able to to this at the right time.
