I'd suggest using a combination distilled vinegar + an old toothbrush to neutralize the alkaline chemical (you can use some baking soda to neutralize THAT), then alcohol to rinse that away & help dry the contacts.
I just did this in a whim before goggling and watching this vid. After taking out the four batteries I sprayed where all the brown liquid corrosion was with alcohol..wiped down and used q-tips too. Now I have get more battery's to see if my little LED lantern will work again. Will report back later. I was glad to see that my wild guess to use alcohol was an option too. Thx.
The bottom of my long flashlight has heavy, HARD corrosion. It's the inside of the part you screw off on the end, to access the battery area. I think it needs to be clean to keep the connection. It's as hard as a rock. How do you get that out ? I thought of sandpaper, but thought I'd ask first. Thanks.
Just tried it. Worked perfectly, thank you. Now to try the second one... Incase someone has the green 70% Isopropyl alcohol this works as well it's what I used...

Nyogel 760 G every 4 months after cleaning the contacts as you presented with robbing alcohol 70 percent .. Good video. !
I greatly appreciate it. Thank you

Vinegar or lemon juice works to neutralize battery acid also...
Neutralize acid with acid? Vinegar will clean it for sure
Thanks for sharing…worked perfectly!😊✌🏽

I would let it soak in rubbing alcohol or coke
