Hey everyone
I have a friend who is stripping all the wood in their house, all doors trim and baseboards. They used TSP, wiped that down with a clean rag and then some sanding. This is the only door that looked like this after that process. Does anyone know why this happened? And any ways to remedy it?
Included pic of another door to show how everything else looks. They are maple.

Edit: the spots showed up after the TSP, before sanding. They tried sanding more to get it out, but that made it worse

So I checked online to track my refund, and this is what it says on the Ohio Tax Refund tracker. Does anyone know if that means I’ll actually get the deposit Weds? Or does that only mean it’s approved and will be released then, so I actually won’t see it for a few days following the 13th? Any insight would be appreciated!!!
