Do you wash socks and underwear...

all towels separate. real dirty stuff separate. No order. I use microfiber clothes and only wash them with sheets because towel lint messes them up.

Nope. I do everything in one load, and have no issues. I don’t find the need to separate anything, clothing wise, except maybe jeans, if I have a full load. I do towels, blankets and sheets separately, but that’s it.

Undies and socks get mixed in.

Lights
Darks
Towels, sheeets,blankets, cleaning cloths

I'm such a lazy housewife

Laundry is separated by:

Lights/whites (anything that is pastel or white)
Darks (anything that's not light )
Dh's work clothes and anything else that gets a gentle cycle
Towels (most of our towels are dark-ish; but the random white ones go with the regular light load unless I've saved them up for awhile {rare}, and if the dark load isn't full then I'll throw a towel or two in with them just because)
sheets (just cuz they're bulky, but if there's a random pillowcase then it goes in the dark load too)

The dog get cheap fleece blankets from walmart, he uses them for awhile then they get pitched, there's just too much fur. If i wash his crate cover or a random blanket for whatever reason it gets washed last and not before a dark load.

On the off chance I use bleach I don't wash a dark or gentle load right afterwards, I'll do towels or a light load just in case there's a smidge of bleach left.

We use primarily all white towels so any white clothing gets tossed in with those and some bleach.

Sheets are washed alone unless there are some decorative colored towels to throw in.

Everything else is basically washed by person. I like to do loads by person because it makes hanging/folding/putting away so much easier.

No, socks and undies get mixed in with everything else depending on what color they are.

Dish towels are mostly white and go in with our whites.

I wash socks and underwear separate because I like to wash them in hot and I wash pretty much all our regular clothes in cold.

I use a ton of microfiber towels for cleaning and those are a separate load as well - I have a basket I toss them when and when there's enough for a full load, I wash them. Kitchen towels go in here too.

Other categorizations: 
clothes, dark/medium (newer dark wash jeans or other things prone to bleeding are washed separately)
clothes, light/white
sports uniforms/workout wear
towels
sheets
random other things as needed


Also, I LOVE Shout Color Catchers so I don't have to be quite so vigilant about mixing colors. 

All the clothes get tossed in together for the most part. I separate out anything that needs to go on a delicate cycle, but the rest gets washed together on Perm. Press cycle. DH does his own laundry and tosses it all in together. If there is something new, we toss a few Color Catchers in with the clothes. Never had a problem.

Bath towels & dish towels get washed together.
Cleaning cloths and microfiber mop heads get washed together on hot right after the housekeeper leaves.
Sheets separately because one set fills up the washer.
Dog blankets get washed separately due to the hair factor. After that cycle I will run the tub clean cycle about once a month.

Undies & socks, washed in hot with bleach/ color safe bleach.

Clothes, separated by light and dark.

Extremely dirty clothes (think vomit) washed separately.

Towels, washclothes, kitchen towels.

Sheets & pillowcases.

Socks and underwear get washed with the colors they match

Towels including kitchen get their own load

I do dark gentle, dark regular, light gentle, light regular, sheets, towels, whites. Or something approximating that depending on what I need to wash on any given day.

That is when I run my clean cycle too with a tab

-Sheets get washed by themselves
-bath and dish towels together
-towels for the counters or floors go into the cleaning rags wash 
-clothes are separated into colors or whites then Regular or light wash
-dog blankets and bed go together 
-DH does his own laundry. I do mine and the rest of the above because I don’t trust his washing machine settings. Lol

I have enough laundry that I can usually separate types of loads and not waste water/energy
Sheets in hot water to kill dust mites.
Towels because they are fuzzy
Things that need cl bleach
I soak socks because we seem to all have really stinky feet and get them really dirty.
Of course darks, lights, delicates

The only order is what is most needed

I do all my laundry on one day so there is enough I can seperate it out
Socks, underwear, cleaning rags
Sheets
Towels - bath and kitchen
Athletic - lululemon leggings etc and hang to dry
Jeans and thick hoodies - take a long time in the dryer
Shirts - maybe more than one load
DHs work clothes as needed
DHs hockey or ball equipment as needed
