Then wash it out with hot water and yer favorite dish soap, taking care to use HOT water.
then flash the tank with your lit propane torch,( sticking it in the filler hole after tank dries) the worse it will do if properly cleaned out is nothing, or a slight whoosh maybe if a little residue is left in a tank seam.
I've been welding gas tanks for 60+ years, never had one "done blow up" as they say in NASCAR
FWIW some of the newer tanks like on Briggs have an epoxy sealer or resin in the seam of the tank halves.
Welding heat will make those seams leak.
Also older kohler tanks that have seems soldered or outlet bungs soldered, they can leak requiring re sweating the seam or bung when heated enough from welding.
Don't singe yer eyebrows or beard/mustache while flashing
