I don’t know for sure, but I think you have a barrel type jack; 1.5 or so inches long that goes through the wood at the edge of the body. If so, and the ‘93 Foundation has been used a lot, the cleaning might be a temporary fix.
Barrel jacks are kinda average when they are new. The spring terminal that snaps into the recessed area around the tip of your cable connector when you plug it in is not a very robust on most barrel jacks. There’s not enough room inside the jack to build it beefy. Some are better than others, and the best one you can acquire is the one to get if you have to replace one.
If your bass has a chrome plate on the edge of the body with a jack mounted in that plate, you can get a much better quality jack to replace it.
