How to clean old bottles and stoneware with muriatic acid.
Things you will need
2 plastic buckets
Baking soda
Eye protection
Chemical gloves
Water
Muriatic Acid
Muriatic acid will react to metal so use plastic buckets only. The fumes can corrode metal items near the acid so its a good idea to have lids for your buckets. Use only in a well ventilated area. Wearing a respirator is also a good idea.
First- Fill a plastic bucket ½ way with water then fill the rest with muriatic acid.
***Important note- Pour acid to water NOT water to acid or a reaction can happen.
Next- Get another plastic bucket and mix baking soda with water to neutralize the acid on the bottles when they are done soaking in the acid. I then wash the bottles with soap and water to remove any residue that’s still on the bottles.
To clean stoneware items you need to be careful. Muriatic acid could etch or damage stoneware items so its a good idea to test it on a shard of whatever you are using it on.
Porous stoneware the acid can seep into the stoneware itself. However long you leave the stoneware in acid for leave it in water and baking soda to neutralize the acid for the same amount of time. You might need to change out the water and baking soda if its getting discolored or smelling like acid.
Conclusion- Muriatic acid works very well and is fast to remove rust stains and organic stains left behind on old bottles. It dose NOT work on sick glass to remove the white film/stains that are etched in the glass.
I have used many different products over the years for cleaning old bottles. Safer products such as vinegar or CLR do work but takes more time to clean.
Anything I missed I will add in the description.
I noticed I added the straight sided coke twice in the clean up.
Tips
Tilt bottle on a angle as show in video clip 1:40 mark to prevent the acid from splashing.
Muriatic acid will stain/damage clothes if it gets on them.
Put in the most dirty bottles last because when your bottles start to bubble you don't want to breath in those gases.
Most bottles only need 30mins to an hour in the acid but it wont hurt them leaving them in for days/weeks at a time.

You might need to brush off some residue but for the most part the acid dose all the work.
