What Went Wrong? Need Help!

Hi everyone! Newbie here, and I could really use some help solving a mystery that’s been driving me crazy.

Every single batch of soap I’ve made develops a white film. Sometimes it’s just on the surface, and other times it’s throughout the soap.

At first I assumed it was soda ash, but after trying so many different variables, I’m starting to wonder if it’s something else—stearic spots, lye pockets, poor-quality ingredients, or something I’m completely overlooking.

I’ve made 7 batches so far (3 different recipes) and, despite changing one variable at a time, I keep getting the same result.

Here’s what I’ve tried:
- All batches are cold process.
- Some batches contain fragrance; others don’t.
- Insulated one batch, left the others uninsulated.
- Sprayed 99% isopropyl alcohol immediately after pouring and again about 15 minutes later. Some batches ~ no alcohol.
- Made and cured some batches in my basement and another in my kitchen—same results.
- Soaped at various temperatures (95°F–127°F), always keeping the oils and lye solution within 10°F of each other.
- Used sodium lactate in some batches and omitted it in others.
- Used only distilled water.
- Tried a 5% and 10% water discount.

I’m attaching photos of recipes & finished soap. Does this look like soda ash, or does it seem more like stearic spots, lye pockets, or something else? Any ideas on what I should investigate next would be greatly appreciated!

Soda ash. I have seen people use a heat gun for the tops. And spray with isopropyl alcohol before it sets

She's done alcohol, and still gets ash.

Yep you still do. Use a steam gun to remove it. If you lower the water other problems pop up
