Activator with debris from dropper/cap

Hello everyone... I have some 4% percent HCI solution/activator which when shipped to me eroded the plastic under the dropper cap and fell into the solution.    So I have the Activator with "debris"- plastic rubber floating in it.   I informed those who sent it to me what had happened and I was told  " it is Acid...simply filter it out... and you can use it"     What are your thoughts?      since it is being used internally etc...     What they suggested to do makes sense since it is acid but I don't know if it in FACT is safe to use -  Thanks for your input...

My first bottle of HCL activator did the same thing. I noticed the floaties one day, realized that the acid ate thru part of the rubber dropper top. I just threw it away and made another bottle up with an all plastic bottle. No problems since. I have no clue how you could filter it out. It would have to be one super fine filter that could put up with the acid. Never heard of such a thing
