This is the approach I use https://www.wikihow.com/Clean-Keycaps

Denture tablets are gentle enough to not remove the legends from the keycap, especially if its laser printed and not etched, double shot, or dye sublimated legends. You can speed the drying process by putting your keycaps in a dryer bag wrapped with a towel and shaking the water loose from the keycaps. As for cleaning the rest of the board, i use an air duster to blow out any "board chow" that has settled between the keycap posts. For the rest of the keyboard, water with a drop or two if dishwasher detergent. You can use other cleaners but be careful of stronger, undiluted solvents as the denaturing effect in some ingredients will ruin the case over time.
