The skin of the Apollo Lunar Module was made thinner by using an acid wash method. What are these people thinking?

Aluminum will go to hell via both acids and bases.

Some acids are not as destructive to aluminum as others, but sulfuric and hydrochloric will both mess it up. As far as bases go, there is a reason you don't expose aluminum to stuff like lye.

The public is being sold a bill of goods on this Ohio incident, and it is making for some strange bedfellows. "Trust but verify."

Phosphoric acid used in the early days of the semiconductor industry. I still have a collection of the blue 4 inch wafer boxes in my tool shed...for various nuts bolts etc...

I made hydrogen ballons in HS.

Recipie:

In a glass soda bottle add 4 oz. warm water, a tsp of lye and a 3” square of aluminum foil ‘balled up’

Place a balloon over the neck of the bottle and you are crating hydrogen balloons.

Warning - VERY flammable!
