The hippogriff can hear the pony’s voice from inside “Coming!” and a few seconds later the door opens “Oh. Hey there Vindicar.”
"Yeah. Quite heavy piece of work. I haven’t become fully used to it." Griffpony smirks sheepishly, his shoes clanking audibly. "So, what do you make of it?"
"Well" He moves his hoof over the chainmail parts between plates "Those parts seem like will be the easiest to clean" He goes over the wing covers "Those are more tightly packed, so it may need a more thorough use of the air pump." He the goes over behind the griff, to the mail-only part covering his rump "Hmmmm" He pats it lightly "Yeah, that’s something between the wings and first part, it shouldn’t be problematic. I think that what I thought up should work then."
Vindicar nods. “Cuirass is easy to clean, and the chainmail underneath it is pretty plain too. But yeah, let’s try it out then. Got anything roomy enough to submerge my armor completely?”
“Well, it depends. Does the armor stay as huge as you when you take it off, or does it ‘deflate’? Because I may have trouble finding something your size”
