After carto cleaning tricks for air hole?

[MikeyB]

Anyone have any? I am not talking about cleaning but more so how to keep the cart so that air flow is at the best! I have noticed that the first time it still has great flow but after another cleaning it gets a bit harder to suck. So I stuck it in the light looked into it and noticed that the middle area was not as big/clear from one side to the other like when they are new.

So my question is, does anyone have a trick to keep the middle hole from the battery end to the mouth end (that is in the middle) straight, clean, and clear so that you get that nice big each time you refill!

I call it a air hole, you call it what you like...

I use a soft bristle toothbrush and just twist it around to clean that area out.

I don't know what you call it either, but I know what you mean.

I use a straightened out paper clip. I gently put it in from one end (so it goes all the way through) and work it around to "wallow" out the tube. Then I put it in from the opposite end and repeat.

It works for me.

Thats about what I do, except I use a needle(thick one) seems to work pretty good for me.

i was using a needle, I will try the paper clip tomorrow after they are dry! Just washed about 5 of them and wanted to try some new ideas, thank you!

I just tried the paperclip a few minutes ago...It did a nice job with a cart I was having trouble with as far as looking for daylight at the other end...many thanks.

Thank you for testing that for me before I did tomorrow

after a few cleanings the glass fiber tube that keeps the opening clear starts to collapse, once that happens its best to just toss it in the trash. the paper clip trick works but the effect doesn’t last long........and sticking things in the air hole can also cause that little tube to fail and collapse.
btw i notice this more after boiling.......
