crackling in first minutes after steam cleaning

Hi,

I have been steam cleaning my records lately and have noticed that after cleaning, a few have a very noisy crackling sound at the beginning of the records, from the first 30secs to 2 minutes depending on the record. I have been using the same cleaning method for all my records, but only some have had this problem, and only at the beginning. Others are so silent I sometimes think I have the mute on.
I sacrificed one lp to further steaming in the name of science and held the steamer very close to try to "power" out the crackling which I am assuming is debris of some sort, but it got worse.
At first I thought maybe it is because I am heating my cleaning solution which has alcohol in it, but if that were the case, I should have the same problem throughout the record.
Another possibility is my steamer is spraying out something in the first blast at the beginning of the record that passes quickly.

Could it be in the pressing? Is this a common place for pressing problem to occur?
Other then this issue, I like the results from steam cleaning, but these records did not have the crackling before I steam cleaned them, and while I have been using records that I can replace and are still in print ( mostly :( ), it is so random and unpredictable that I am considering stopping the steaming for fear of damaging one of my favorites.

Has anyone seen this before
