another couple offered to share their toys with us for the night and i didnt know how to decline politely... hygiene rules anyone

tldr couple loaned us a couple of big toys mid-play and i panicked. need a hygiene/etiquette sanity check before next time. so we're a couple in our forties, been in the LS about 6 yrs, full swap, mostly through a private group in the leeds area. weve started getting into bigger toys at home — proper sized vibrators, a few plugs, that kinda thing. the other couple we've been playing with regularly knew this about us cause weve mentioned it in chat. last weekend at theirs they pulled out a drawer of their own collection mid-session and said "feel free, theyre all clean, just hose them after". they meant it kindly. but in my head i was instantly going "clean how, since when, with what". like ive seen the chemistry stuff about silicone porosity and i know proper cleaning matters but i had no idea what their actual hygiene routine was and i wasnt about to do a deep dive standing there in my pants. i muttered something about being knackered and we used my own small one i had in my bag. the moment passed without drama but ive been thinking about it since. what's the actual right etiquette here. is it normal to share toys between couples and im being prudish, or is it actually a hygiene risk and im right to have hesitated. and how do you politely say "i appreciate the offer but i prefer my own toys" without making it weird with people you're otherwise close with. also a more uncomfortable q — if a couple does share their toys with multiple play partners over time, what should i be asking about cleaning protocols before agreeing. cause im not the type to ask "do you bleach this" with a straight face but maybe i should be
