I don't use it for data so does it matter? If so how lol.
... i am not sure, what you mean with "clean rubbish from sd card...".
you don't have to clean anything. when you have a good setup with the UUIDs, where it was working, and you now want to change from using UUIDs to LABELs, you only need to change the used fstab and change the UUID=1234 statement to LABEL=myLabel statement corresponding with the filesystems label your want to mount.
notice, that working with labels will mount every device where the label name and the filesystem type matches in the same way (big advanteg)... that means, if you have more than one usb device with the same label and filesystem type(independent of its ID/UUID), it will be mountet as it is written in the fstab. but then do not plug both devices at the same time to the same computer - i have never tried and have no idea, what happened then...
