I spilled rubbing alcohol in my acrylic tub and forgot to rinse it. It sat overnight, and now I have a white area

color is originally white, but now this area is lighter. How can I fix it?

Assuming this is not just a surficial residue which can be rubbed out with a non-abrasive cleaner:

If you know the brand or the dealer, I would contact them for suggestions - but I suspect a spa/jacuzzi/hot tub dealer who does repairs is the answer, to use a mild abrasive to buff it down to bare material (below the bleached zone) then polish it back to original smooth finish and reapply any sealer/gloss coat it had on it. Some bathtub refinishing companies might also do this sort of work.

Unfortunately, denatured alcohol is the normal solvent to remove the clear finish on many acrylic products - so letting rubbing alcohol sit on it probably softened/lifted the clear coat, so the "good as new" fix would be to buff that damaged clear coat off, polish the tub surface in that area to blend, then reapply the clearcoat (which is commonly a silicone based sealer).

DIY - though might make it worse so go easy, and would certainly roughen that area up a touch (relative to the original gloss coat, which might be what whitened) so it would retain dirt and stain a bit more - using a mildly abrasive cleaner like is sold for cleaning glass-top ranges or plexiglass. You may be able to get touch-up bottles of clear coat for the tub - but jwould probably need to know the brand to get the matching product, because some use silicone products, some epoxy, some resin, etc. - and many of those will be gorssly incompatible with the others so you need the right one.
