OG Westy seat covers

Can I unzip the top bunk ones and put them on a wool wash in the machine or would that wreck them/shrink them/remove the odd backing material and make them useless?

 

Put them inside a pillowcase on a delicates cool wash. It's not so much the temperature than the agitation that does the damage

 

I turned mine inside out and they came out fine.

 

Washed loads with no I'll affect

 

Thanks all
