I have a canvas tote from some bookstore in London that I bought in 1987. I still use it. The handles are darker than the rest of the bag now and there is a stain near the bottom that never came out, but the thing refuses to die.
I have gone through maybe fifteen totes in the last six years. Most of them ended up in the trash because the handles ripped or the fabric got that sour smell that does not wash out.
So I wanted to know what I did differently.
Someone laughed and said I don't do anything. I just use the bag and wash it when it looks dirty. Cold water. Hang it on the line. That's it.
The Weight Factor
I think the difference is that my bag is heavier cotton. The ones companies hand out at conferences are thin. Barely any weight to them. They feel cheap because they are cheap. The fabric starts pilling after a few washes and the seams pull apart at the corners where the stress is.
The bags that last are the ones with some heft. Twelve ounce canvas or heavier. The kind you actually have to pay for.
But even those will fall apart if you treat them badly.
Heat Is the Enemy
Heat is the big one. I ruined a bag by leaving it in the car during summer. Forgot it was in the trunk. When I found it a week later the whole thing had shrunk and gone stiff. Texas heat will do that. The cotton fibers contract and they don't relax again.
Same thing happens in the dryer. My wife throws everything in the dryer on high and I have learned not to leave my bags anywhere she might find them. One cycle and the bag is done.
Cold wash. Hang dry. Not complicated.
Dealing with Stains
Stains are trickier. The cotton soaks things up and holds onto them. Anything with oil in it is bad news. I got bacon grease on one bag and tried to wash it out three days later. The spot faded but never disappeared. Should have dealt with it right away. Dish soap on a wet rag before the stain sets. That usually works.
The Mold Problem
Mold is the other thing. Cotton plus moisture plus no airflow equals that musty smell and sometimes actual visible fuzz growing on the fabric. Happened to me with a bag I left in the garage over winter. The garage is not climate controlled and we get humid summers here. By spring the bag had green spots on it. Threw it out.
The fix is boring. Keep them somewhere dry. A closet with decent air circulation is fine. Some people put those little silica packets in with their bags. I don't bother with any of that. My house is just not that humid I guess.
The Environmental Math
There is a study from Denmark that gets mentioned whenever anyone talks about cotton bags and the environment. It says you need to use a cotton bag something like seven thousand times before it offsets the environmental cost of making it. That number sounds made up but it comes from an actual government report. The calculation depends on a lot of assumptions though. What counts as environmental cost. How you measure it. Whether you factor in what happens to plastic bags in the ocean. Different assumptions give you different numbers.
I don't know if I've used my bag seven thousand times. Probably not. But I've used it more than I have used any of my other ones, and that has to count for something.
The Simple Truth
The bags that survive are the ones that get used. Seems simple but most of the totes people own just sit in a pile. Exposed to nothing. Protected from nothing. Eventually thrown away without ever being unfolded.
