White film after cleaning

This is oxidation that was not fully removed. Best to go over it again. Do in sections and get slightly closer to the wood with the pressure washing. You may not remove all but more should come off. Brighten after.

FYI, it is okay if a little bit of this shows when dry. It will disappear when it is stained.

Do we need to spray the cleaner again or just pressure wash? And can I wait 24 hours to brighten or does it need to be done immediately afterwards? Thank you so much for your help! 

Apply cleaner and pressure wash off,.Brighten same day while wood is wet.

I have the same problem with untreated cedar.   I power washed it twice now and yes some does come off every time. Now what will the brightner do? The homeowner wants me to stain it with a clear coat stain/UV protector. Will the white section that doesn’t come off show a different color after I stain it. Also how long before the cedar starts to turn brown?

That is furring of the wood from over-oxidation. It typically does not show that much when you apply a stain. Cedar does not brown, it grays form UV

So I could I power wash one more time before applying a/the stain? Usually how long does it takes for the boards to fully dry after rain? I was told 3. I just want to make sure.

You can prep one more time. 2 days after rain.

Being that the Wood is over oxidated there’s no need to brighten up the wood.

I’m using Cabot clear coat stain, your feelings

It will do nothing for UV protection. You need a tinted stain if you want to prevent graying. Cabot stains are not high quality like they used to be since they were bought by Zinser.

If the boards are oxidize. What stain do you recommend I use if the homeowner wants that cedar wet look? I don’t want to have the oxidize parts looking yellow etc.

Try TWP stains in Honeytone.

Can or would Stain/paint stripper take off that white film that’s still the wood? Because these photos were taken by me 5min ago and it rained out all day yesterday . Thank you for your assistance. It’s greatly appreciated.

Stripper would not remove it. See this:
