i'm such a lucky gal..... i get to use communal coin operated laundry in my apartment building. yay! not. bloody expensive at 2.50 a wash and the same for a dry. needless to say, i do laundry only when absolutely necessary.
for chin laundry, if it's just a few liners, i'll toss them in with my clothes or with whatever load is going in that day. if it's all the chin laundry (all liners, hammocks, fleece houses, etc) then that's a full load and i tick off the boys by making their cages barren for a couple hours, lol. i really need to invest in some spare hammocks!
what i do with fleece stuff that gets pee on it (liners mostly) is to pre-soak it in a bucket with hot water and a dash of un-scented laundry detergent for a while. this gets the pee stains out without me having to use vinegar (i really dislike the smell of it). if i'm pre-soaking the full chin laundry load i'll use the bathtub in our second bathroom as a 'big bucket' for pre-soaking. works pretty good for me.
liners i'm constantly washing, because Rhino likes to pee on his cage bottom liner, and Guss has taken to peeing on one of his fleece shelf liners lately too. hammocks, fleece houses, tube covers, cuddle buddies etc, i wash less often, probably twice a month at most. the don't get dirty really, just covered in hair.
a sticky lint roller works wonders for chin fur stuck on fleece!
