11. Now, the tumbler should be rinsed out with clean water a number of times until the water looks clear. Swish the shot around with your fingers each time you rinse also.
12. Once it’s been rinsed well, fill the tumbler with water up to the minimum water level.
13. Pour ammonia (a good name brand – not the cheap stuff) into the tumbler until the water level rises to the maximum line.
14. Place the tumbler on the base, plug in the machine, set the timer for five minutes, and turn it on.
15. After the timer goes off, again rinse the shot thoroughly. The water will probably be very black after the first few rinses.
16. If the shot still seems dirty after much rinsing, repeat this procedure again (steps 12 to 15).
