No, pure acetone doesn't truly expire and can last for years if sealed, but its effectiveness can decrease if exposed to air, water, or light, causing it to evaporate, dilute, or potentially crystallize; nail polish removers with additives might "spoil" or lose potency faster, so always store it tightly capped in a cool, dark place.
100% acetone is considered hazardous waste and should not be reused.
Nail polish remover has an expiration date and will stop working. Same bad smell, just no removal of polish.
The FDA does not designate the shelf life of nail polishes, instead they leave it up to the companies. Typically a nail polish can last from 18 to 24 months if they are kept in a cool dark place. You can however use the nail polish LONGER than 24 months if it has not gone bad.
The ``correct'' way to dispose of it is to ``Burn in a chemical incinerator equipped with an afterburner and scrubber but exert extra care in igniting as this material is highly flammable.'' according to the SDS, but you're unlikely to be able to do that, so don't even try.

The EPA considers nail polish remover to be hazardous waste, and it needs to be disposed of as such. To keep waterways clean, never dump it down the drain.
Using old polish, especially if it's been shared or used on infected nails, can spread the fungus to your healthy nails. Ignoring nail health and frequently applying nail polish causes fungus, especially if the polish isn't removed regularly.

For $70 nails, a standard tip is $10.50 to $14 (15-20%), but you should tip more for excellent service, complex designs (like chrome or detailed art), or if your technician spent extra time, potentially reaching $17.50 (25%) or higher, while a tip of around $7-$10 (10-15%) is appropriate if the service was just okay or had minor issues.

If stored correctly, tightly sealed in the original container, acetone is not likely to degrade. In fact, it is expected to have an indefinite shelf life.
Nail polish can also thicken because it's been mixed with another product, like acetone nail polish remover. This is done to create a new color or add a shimmer. Nail polishes that have multiple colors in them are usually the ones most likely to do this.
