I use gasoline as a home goo-gone substitute for removing labels.

If the base material can tolerate some heat, use a hot air heat gun:

I don't know what kind of labels you're using, but the ones that I
have to remove from customers laptops uses easy to remove rubber
cement type glue, that is easily dissolved with almost any hydrocarbon
solvent. The trick is to let the solvent soak into the paper label or
soften the edge of a metal label. I think I use paint thinner.

However, I sometimes run into old labels where the glue has hardened
to something like a rock. For those, I mechanically scrape off most
of the label with a plastic razor blade paint scraper, and then attack
with the solvent.

Well, you could try using something that was actually formulated for
removing labels:
3M General Purpose Adhesive Cleaner, Quart, 08984

Ouch. Rather expensive at $25/quart.
SDS shows interesting and noxious chemicals:

For naphtha, use Coleman camp fuel. Xylene and toluene are no longer
available in California, so those won't work.

There are made for purpose label removers, all of which really smell
awful. Goop-Off, Un-Du, Turtle Wax T-529, Goo-Gone, etc.

Then, there are the home concoctions:

I remove the labels on some 3.5 gallon food grade buckets by cutting
paper towel the size of the label, lay it over the label and then put
just enough Xylene on the paper towel to wet it. I wait 5 minutes and
the label will peel off whole with no problem. Sometimes I need to use
the paper towel to remove residual glue.
Before I found that, I could spend a hour scraping off the label. now
I can get 20 done in less than an hour.
