If you 'snap' the washing when you hang it out, it doesn't need ironing at all.
Well you can tell yourself this...
Now I am American...granted...but with cotton (shirts and trousers) and wool (suit trousers), you want the crease. None of this class-based crap thing with creases. If the shirt is silk, sure, no creases....but the decision to crease or not is clearly related to material....not to managerial status. I hope we can agree on this.
Now if you are going for the crease, do it right. Just because Nan liked to "snap".....doesn't mean a thing....she also believed she could communicate with her departed uncle Nigel too.
So, how do you get a good rigid crease? First of all separate the laundry by material and colour. Stick all the delicates aside - they are a whole separate topic. Polyester stuff you can just bung in the wash and do what you like...
Now wool.....just to get rid of this one. If you can, just sponge and air...it is a forgiving fabric but can lose its shape. Treat with a bit more care.
But to the kernel.....the point of it all: cotton. White cottons should be soaked occasionally in a very weak bleach solution. Armpits and collars can be treated with a stain stick. Washed hot. Spun thoroughly. If it makes you feel better snap the hell out of them....Nan will beam - she has done well in passing down her knowledge....but it is neither here nor there. Hang up indoors. When they are about half dry, iron with a heavy iron and add a starch spray to really get the board-like quality that keeps the crease all day. Hang on wooden or plastic hanger and be sure to button the top button.
Coloured cotton, basically the same way, just no bleach and lower washing temp.
I have a really sturdy ironing board and a heavy iron for cottons. Steam is not that big of an issue as the clothes are, again, slightly damp.
I have a light weight iron that steams like a locomotive for delicates and polyesters....but again that is another topic.
