s/o What is your "ick factor" tolerance?

I'm with you. My kids shower about every third day. Not a big deal to me. We all wear clothes more than once between washings (except undies- maybe that's my icky tolerance).I don't vacuum every day, I don't change/wash my bedding weekly.

I drink milk past the expiration, if it still smells decent. I cut the mold off the cheese and keep on grating. Etcetera.

I do have my kids change as soon as they get home if we've been someplace with pets, because I am allergic. I have no ick factor about animals at all. I like them. But my body doesn't like them. So if we visit a farm, or grandma's with her 3 cats and 2 dogs, then we change when we get home. But again, not due to anything icky. Just due to everything itchy & sneezy.

I can't use towels twice.
I can't abide long toenails or sputum.
I don't eat food that I can't trust.
Apart from that, I'm pretty easy going. I have no idea what Purell is and can't be arsed to google it.

Dirty feet and dirt under the nails. Totally grosses me out.

Well I guess I'm pretty tolerant of ick. My daughter is an equestrian. I spend a lot of time in the barn, surrounded by dirt and horse shit. It doesn't bother me in the least. I'm not a militant hand washer and I loathe hand sanitizer. My immune system must be super strong, because I rarely get sick. I will eat at the buffet at our club without batting an eye. However, my house is very very clean. Not because I'm a germaphobe, but because I like it that way.

I don't consider myself a germaphobe, but I do have a couple of rules:

I will eat pretty much anything my friends cook (apart from foods I don't like which there are very few of)
I will eat cake/baked goods from people at work even if they aren't actual friends (i.e. we don't socialise out of work)
Luckily "pot lucks" aren't a thing here and at one time they did try to get something like that started at work but only a couple of people were interested so it fizzled out really fast, but I would not eat savoury/hot cold/meat dishes from work colleagues. I also never ate food brought in by patient's relatives if it wasn't packaged/wrapped.

The kitchen is only for clean handwashing and food prep (cue Burning Feather to quote this and make her usual comment about cat faeces all over my house ).
All other handwashing or washing of anything else is done in the bathroom.
No peeing in the shower, not at all worried about germs here, but there's a toilet right there 2 steps away and I'm a civilised person and I'm not that lazy so I'll use that thank-you.

I do all normal daily activities, including using public toilets, sitting on the seat and washing my hands.
However if I've been out shopping, walking around touching things (stair rails etc) then I will not eat anything until I have washed my hands or used hand sanitiser. I carry hand sanitiser or wet wipes in my bag, but I only use them if I am about to eat while out or if a public toilet wasn't clean enough for normal handwashing (or tap didn't work etc), but I'm not using the hand sanitiser in the course of a normal day.
I do wash my hands pretty much as the first thing I do when I come home from being out.

I have one little weird thing, that wherever I work I like to use my own coffee cup. I think that comes from years of working in a hospital and seeing all the nasty stuff that gets on patient's crockery. The thought that someone coughed sputum into a cup before I used it is my personal 'ick' limit...yes even though I know it was washed in an industrial dishwater. Even when I switched to office work, the own cup thing stayed with me. Oddly it doesn't bother me in the slightest at coffee shops or restaurants. Totally illogical I know.

My ick tolerance level is pretty high. I will reuse towels and wear clothing more than once, etc. I do carry a small bottle of hand sanitizer, but it's probably over a year old and still 1/2 full - the only time I remember using it is when I've been at the dog park and had to use a porta-potty.

The only thing I can think of that I'm irrationally grossed out about is those hand dryers you see in public restrooms. Yes, let's take super-heated fecal particles and blow them all over our clean hands. BLECH!

Same here. I keep myself clean, my house clean, and don't lick anything that shouldn't be licked. ;-) I don't overthink it; just be sensible and not irrational.

I couldn't function at the level of "anti-ick" I'm reading - it's inhibits living. I'm guessing that in addition to no potlucks, there's a lot of other activities that fall on the "too icky" list for some - swimming pools, amusement parks, camping....

PS - the reason I don't do buffets very often is because there are so many better-tasting restaurants I would rather eat at...if I'm going out to eat, I want some really good eats!

I don't have many things that truly ick me out but I'm a big hand washer. I can't stand anything sticky or dirty on them, I wash them as soon as I come in usually more than once before I trust that they're clean. I can't stand dirty fingernails on other people.
Towels are changed after every shower, I stayed at someone's house once and their towels were slimy
Tea towels are changed many times a day.
Clothes are worn once and washed.

I love our UK peas!

Wow, some of you would never set foot in my house!

Towels are used at least a few days before they are washed - often a week if it's not too humid (and they don't get stinky).
Sheets washed once a week.
We don't wear shoes in the house, but that's a comfort thing for us, not a cleanliness thing. If you want to keep your shoes on at my house, feel free.
Kitchen towels are changed every day, but I do use a sponge for washing dishes (that's the only thing it's used for - not for wiping the counters) and it goes in the dishwasher every time we run it.
We have cats AND dogs and their hair is everywhere most of the time. Super gross: one of my dogs had diarrhea in her crate during the day, and when I got home, she was covered in it. The crate was also covered inside, and somehow she'd gotten it out on the floor, too. I had to wash the dog twice, sanitize the crate, sanitize the floor and then wash all my clothes and the towel I'd used to dry her. I flatter myself that a lesser woman would have taken a look at the poop-covered dog and crate and just set the house on fire instead of dealing with it.

That's why I admit when my personal quirks are illogical, because otherwise illogical things like that get to me, too.  But when someone flat out says "Yep, I'm illogical and I own it", then I'm all good with it.   You know, just in case anyone is dying for me to be okay with you!
