Do you wash your coffee cup?

I wash my coffee cup using Dawn Ultra and rinse. Then I rinse again with natural spring water. I wouldn't want bacteria growing on the rim of my cup before using again after 24 hours.

"Some microbiologists say that leaving your cup of coffee for any longer than 45 minutes after pouring it is unhealthy since standing liquid can encourage pathogens like mold to grow".

Some people say it's only a problem if you use sugar and cream...BUT...my thought process is, what about bacteria from your mouth...that's why we brush our teeth everyday.
 

I rinse mine, drink the water and wipe it out with a paper towel which I then re-use for something in the kitchen.

I'll do this for several days or close to a week, then it's in the dishwasher and I use another mug. Except for one handmade one I bought from Etsy, all my mugs are thrift vintage finds.
 
I use a mason jar with lid and stainless steel straw for coffee. Since I drink microwaved instant coffee day and night, I just rinse it all off and start over again. About once a week, I'll take steel wool to the stuff to scrape off the residue (just because it looks unsightly on clear glass, not because I'm concerned over health or flavor). However, when it comes to flatware, I'm a cleaning fiend! I'll even rewash things in restaurants before using them!

@palides2021 What is RO water?

Reverse Osmosis: https://en.wikipedia.org/wiki/Reverse_osmosis

"Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules and larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended chemical species as well as biological ones (principally bacteria) from water, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as solvent molecules, e.g., water, H2O) to pass freely.[1]" (I know, too much information!)

In my military days I spent a few years in the Navy, and it was custom that if you owned your own coffee cup you never washed it out because that built up mass of coffee resins inside the coffee cup made the new coffee you put into it taste a little bit better.

During my time aboard an aircraft carrier, the bridge was an in-port hangout for those of us in Navigation Division. One day I noticed that the coffee mess on the bridge was looking pretty grungy and decided to give it a good cleaning. Did a nice job of it, too!

Unfortunately for me, my cleanup included washing all of the coffee mugs . . . including the one that belonged to the chief.

Needless to say, the chief was not pleased. I never heard the end of that! :(
 
I always wash my mug and the Mr. Coffee carafe and the three tall plastic glasses my son uses to microwave his nasty tasting instant coffees each morning. My mug is a giant one my husband got me that says "Leftovers are for quitters." He knows me so well.

Well, all dishes are scrubbed by hand. My favorite chore. The kitchen is my favorite room and I love changing the decor.

I always read your posts and want to go to your house so bad, Pam. I love the kitchen too and dishwashing feels so good on my arthritis hands.

My son and husband kindly get up from the dinner table (while I'm still eating) and carry dishes to the sink and put the condiments back in the fridge. Then I'm in there by myself for about an hour washing things and organizing. I know they wonder what I must be doing since they almost did it all.
 
Reverse osmosis uses and wastes a lot of water, so it's not a good purification choice for people in areas where water can be scarce or rationed - as it is in my area of So Cal.

In any case, the intensive scrubbing people go through with their coffee cups and/or dishes is a little surprising.

My dishes? Wash 'em and forget 'em. Since dishwashers use less water than hand washing, I keep a large Tupperware bowl of water in my sink. Dip them, then hit the dishes with a sponge to remove any goop, then put them in the dishwasher.

When that water gets grimy I repurpose it by flushing a toilet or watering the orange tree, tomatoes, roses and other thirsty plants.

Since we don't eat meat or dairy, the only "bits" in the water are plant based.
 
Prior to rehab for spine repair I used to drink coffee & washed the cup after every use. Prior to rehab I took a prescribed med for high blood pressure. During rehab the coffee they served was so bad I couldn't drink it so I didn't.

After coming home I couldn't take the smell of coffee so I didn't make any. Since stopping coffee I don't need blood pressure meds. My blood pressure typically is 127/65. The coffee cups are part of a set so they will stay to be part of the house & contents that are willed to our sons.

What they do with them I'll never know :) I doubt hoarding them because they have their own stuff will be the way they go.

It just occurred to me that the reason I never saw personal cups may have been our small crew of a little over 80 including officers. There was only one coffeemaker and little room to leave personal cups sitting around in a diesel sub.

It is true that RO produces two water steams, one mostly with salt or other dissolved, and one brine. The salts and dissolved material is not lost, just concentrated into the waste stream.

For drinking water that is too salty to drink it can produce a good water stream, and so long as the brine stream can be safely disposed of it can be a good thing. Expensive and energy demanding it is usually the source of last resort. Some southern California cities such as San Diego do it.

However when used in the home where the tap water does not have high salt content it can be a waste. If concerned about the water you are drinking softening to reduce the sodium, and carbon filtration to remove organics is probably a better option. Probably best to use these only on the tap or taps you drink from, not the whole house.

I believe the documentation for our system says it wastes one part water for each four parts filtered. But, we use very little of it, mostly for the steam iron and I rinse my eyeglasses with it. I don't actually like the taste of it. Our water's good without any filtering, but we have a charcoal filter in the refrigerator anyway. It came with it.
