I've occasionally used CLR on the toilet.Mineral buildup will cause sluggish flushing overtime, even with superior flushing vintage toilets. The trick it to pull the toilet and put it in a large plastic container. Pour straight muriatic acid in tank to bowl opening so it gets in the rim jets and keep pouring until the bowl is full and begins overflowing out the trap way to clean the trap way out (another area that's prone to being clogged with minerals and causes sluggish flushes). A good soak overnight melts it all away. Use baking soda to neutralize the muriatic acid when finished.
I'd drain the bowl first, so the lower bowl jet is clear of water.
Then I pour some down through the tank's overflow tube so it runs out of the rim jets, some comes out of the bowl jet, and let it sit for about 15 minutes.
It dissolves any calcium or lime buildup.
Then..... just flush!
