Chalky/white look to newly stained pine doors

Post some pictures.
What color stain did you use? Did you pre condition the wood as it says in the instructions or did you just put the stain on them?

We used minwax stain called ipswitch. We didn't condition the wood before we stained and actually never have and we've stained several pine doors in the years past. The first few coats of stain didn't really have a problem it wasn't until we were ready to poly.

It's really hard to tell by the photos. Just a guess, but were the previous coats dry before you put down another coat? Sometimes it takes up to three days for some stains to really dry. Putting it on with a brush might have allowed too much stain and if it was hot and humid and you didn't wipe after brushing it would take a while to dry, especially Minwax. That's my best guess.

Is the whiteness on the very outside layer? Did you try wiping with thinner or maybe something a little hotter to see what happens?

Also, did they sit in the sun while drying? If they got to hot, the finish might have expanded and caused problems.
