Hi, to concur I do exactly the same. ie white sheets that goto laundromat, good quality like bamboo. threadcount up above 400. don't need egyptian cotton but certainly not microfibre. agree they pill too easily.
as for the quilt covers or blankets, yep have learnt my lesson and gone for multi coloured small patterns. don't stain as easily and more importantly, dont need ironing with small patterns. nothing with stripes or geometrics either, they show up creases more. as for blankets, just plain dark colours.
and sorry but i don't wash those every guest turn if it looks like the guests stayed between the sheets. maybe monthly or every few months (which for us is probably like 3-6 bookings being a large group property). and with 8 beds, that's alot of washing. when i say wash, i mean we have triples of everything. we run 3 sets to allow for laundromat turnover being a rural property, it can take a week or two.
if i was there though doing it all myself, i would send the sheets and pillowcases to laundromat, and the rest like towels and quilts and blankets, i would wash myself. but don't have option, so it all goes to laundromat and the bill gets quite high if everything was done everytime.
ps saw a comment on coloured sheets. with our single beds, we have gone with quality coloured sheets no problem. just to help us distinguish easily between the QB and SB linen. the other thing i've noticed is that with the single sheets, they never get confused at the laundromat, usually come back. the white queen bed sheets on the other hand, i swear half of them weren't the brand i originally bought, but oh well. i would iron on label them if i had time...
pss my future plan when the white sheets start to go, is to replace with black sheets actually! might be a better chance of them not seeing stains and the laundromat not getting them mixed up....but if the research says white sheets then maybe i should stay with that? and just label them?
psss i'm actually less worried as a guest about quilt covers and blankets, as i'm not sleeping on those, but actually the hygiene of mattress protectors and pillow protectors, cause that's what im sleeping on. i think its disgusting when i strip an airbnb bed, to find stains. I am fastidious about ours and constantly check them all and wash/replace and run spares of those.
hope this helps, regs mary
