What's better for cleaning vinegar or isopropyl alcohol?

Personally I just pee in a jug and wipe any dirty thing with my urine sponge. It worked for my ancestors. 

Reject modernity, embrace tradition.

I don't know what one would use to clean vinegar or alcohol

Neither.  Both over-rated. 

Soap or detergent clean things. Alcohol (after you've cleaned) will cut away soap film.

Vinegar (no matter what the save-the-earth types tell you) is such a weak disinfectant it's virtually useless.

That depends what you are cleaning, and what you are attempting to clean off it.

Alcohol. That is what the hospitals use to sterilize equipment.   Vinegar can grow mold on it.  Not so with alcohol.

I would suggest vinegar which has a PH of 2.5.  This is slightly acidic. Isopropyl alcohol has a ph of 8 which is slightly basic.  In certain cases, a base may clean better than the acid, but in most cases the acidic vinegar is superior.

prefers to use plain water with baking soda in it .

vinegar is much better.

Alcohol. Vinegar stinks up your house for a week.

That depends what you want to clean off what.
