Mist after cleaning

[butelki.danzig]

Hi,

I'm not satisfied with final effect of bottle cleaning.
Bottle looks much betteter than before but is still misty.

Bottle was cleaned following way:
* 3 days 1000 silicon carbide
* 3 days 1200 silicon carbide
* 3 days aluminium oxide

What can I do to make it crystal clear?

What is your rotation speed on the tubes?

Try another 6 days in aluminum oxide. the 1200 grit is kinda course & will need more time to tumble to a shine. Just my amateur opinion? LEON.

P.S. I don't like to use anything courser then my 1500 grit silicone carbide.

P.S.S. I think mine spins at 60 revolutions per minute which some have called on the fast side? I only have one speed, not 2 .

My machine rotete 72-73 rotates per minute.
It's too fast?

That's a good speed. As Leon says above leave it on longer. Do 5-6 days with the 1200. Tumbling is not a fast process, requiring a bit of patience. Don't give up.

Thank You

I would like to show You another bottle.
It get misty again. Previously I got totally different effect.
The only thing I change:
* I add one more tube and machine speed up from 65rpm to 73 rpm
* I bought new silicon carbide. Mabe they mixed 1000 with 1200?

I suggested 6 days in Aluminum Oxide, which is not the same as 1200, it's much finer. Leon.

Good advice for sure. Is it finer that 1 micron or 1/2 micron or something else less than 1500 I'm guessing.

OK, This is just my experience & my opinion. I'm sure others will vary. If a bottle only has light stain or light sickness or minor flaws I never tumble in Silicone Carbide (cutter) or in anything using 1500 grit or courser. I only use Aluminum Oxide fine Polish. That's all they will need. If you have a extremely sick, beat, rough, Bottle then it will need 1500 grit silicone carbide cutter or possibly 1200 if really really bad. Then follow that 1500 grit with aluminum oxide polish. if you use 1200 you might wanta follow that with 1500 then aluminum oxide or if using 1200 & then aluminum oxide it will need much more time to polish due to the big jump in grits. I've heard some people say just keep tumbling it in 1500 & it will eventually break down into a fine polish. For some people this may work but for me in my opinion, bad idea as it did not work for me. LEON.
