Do you take apart your ponies to wash them?

Yeah, I never take the clamps off, since I've never found one rusted - it just seems unnecessary. When I opened up my Starshine though, her clamp broke in half...

Personally, I open up my ponies at any sign of rust, not just extreme rust.

It's a 'sometimes' thing for me. Is the pony's head already 90% of the way off? Is she exhibiting signs of internal distress - tail rust, dark feet (an indicator of internal mold/mildew), bad smell? Is she a pony I am keeping in my collection, and I want to be 100% sure she's okay inside and out? Then the head pops off! Sometimes it depends on rarity too; I'm less hesitant to behead a grimy Cotton Candy, but I get nervous around the higher priced ponies! What if I slip with the knife, and she looks like Frankenstein?!

Well at least she's already green.

LOL, you've got me there!
