Fill to 1/8 to 1/4 inch BELOW the bottom of the split ring,, they do not spit so much if you do that.. IF the batteries need charging make it 1/2 inch or more (Above the plates a bit is good), then charge and top off to 1/8 to 1/4.
But cleaning is routine maintenance.
I have always filled my lead acid house batteries to the BOTTOM OF THE FILLER TUBE (also known as the split ring)... and I have never had an acid overflow problem.... (but ONLY if/when the batteries are FULLY CHARGED).

If/when the cells are filled to the split rings, (aka: "topped off" with distilled water), when the battery voltage is LOW, ..... the electrolyte will overflow as the batteries take a charge.

That Blasted White Corrosive Powder!

I believe the OP's question related to the prevention of battery corrosion. A turkey baster is effective for filling wet cells, but does nothing to prevent corrosion. A battery watering system on the other hand nearly eliminates battery corrosion.

After wire brushing, sanding and cleaning the battery tray and compartment with baking soda, consider covering everything with spray-on liquid rubber. Then use thin grease, spray oil, or spray battery post protection on the slides to protect them from acid vapor.

When I added solar, I changed to AGM batteries and no longer have your problem.
