Man, I really want to get that cleaner. Sounds like it does a great job on things.
I just saw that in the latest Harbor Freight mailing they have a coupon for it - $74.99. Plus, there is the 25% off coupon on the front...out the door for $60.00 is a very nice price. Too bad my vape budget is over spent this month.
Do you like the nautilus as much as you thought you would?
You will see the same US cleaner on Amazon for a lot more but with a different name.
If you go the HF, they also sell a powder for US cleaners that is a degreaser which will take out any of the machine oil taste. Also, try to blow out the air holes as you will definitely find some swarf (metal shavings from machining) in there.
Just rinse very thoroughly. Whenever I do any drastic cleaning, I always remove the O rings and wash them in a glass with dishwasher solution. Even Vodka can swell some O ring material.
Otherwise, I have really been impressed with the FT Kayfun/Russian/Taifun clones. ~$20 allows/each me to play with them.
I was thinking about the Aqua clone, but the small all SS tank with no viewing window was a turn off. I will sometimes rewick with cotton, and I don't like to run that dry.
