Laundry symbols make no sense... So let's get rid of them!

Let's simply make all clothes compatible with a regular wash and tumble dry process.

If the clothes use a dye that isn't waterproof, use a different dye. If the fabric is too fragile to withstand spinning, use a stronger fabric. If a material can't withstand the heat of a dryer, use better material.

Material science has come so far in the past 100 years that we can meet or exceed the performance of pretty much any of last centuries materials while also being able to make the stuff washable.
