Yeah, it's not just toiletries either. I started packing a cheap umbrella and a basic rain jacket after getting soaked and paying triple for one near my hotel. That stuff adds up fast over a few trips.

Wait, colonial-era stuff near Austin? That's throwing me off. Texas was Spanish territory back then, not really a colonial British site. Maybe they're Republic of Texas period buttons from later? Or maybe you meant a different site. Anyway, for soil, you gotta ground balance it. My buddy does this and says mineralized dirt, like red clay, will make it chirp like crazy if you don't adjust it right. He sets his machine over clean ground and lets it auto-tune, or does it manually if the soil's really hot.

Fifty parts is a whole shift? That's a brutal amount of scrap.

My old house had caulk cracks in every single corner.

Have you noticed the sponge leaving any residue? It can smear the dust instead of cleaning it up.
