Polishing up my Abalone collection

I have collected a few shells over winter while spearfishing and have had them on display on my kitchen window sill. figured i would have a go at cleaning up and polishing a few.
SAFETY:
Always wear correct PPE when sanding abalone, the dust can be very bad for your lungs. I swapped to a dust respirator while using a dremel to prevent inhaling the dust.
the key points are take your time and go slow as you can easily put holes in the uneven surface. also always wear a mask/respirator while sanding your shells to avoid breathing in particulates. give us a like if you think i did alright with my polishing

Just make sure you wear a good dust mask for when your are sanding/dremel them, ideally working with it wet will help reduce dust too. The dust can be real bad for the lungs

did you soak in vinegar? where the heck do you buy the acid??

[@Jackhatfieldfreediver]

Can get hydrochloric acid from the hardware store, it's usually used for tidying up paving and brick work. Goes without saying, wear the correct PPE for acid
