My cheats: clean windows make the room look cleaner (and the vinegar seems to "clean the air") failing that, furniture polish sprayed in the room makes it smell clean, lol. We don't use central heating much, but when we do I often put a sheet of the things you put in the dry to soften and freshen clothes behind the rad, they smell great. I have only had one dryer, the one in our London home, but we don't use it that often, I love it but I am used to coping with out so my environmental tingle goes if I dry too much, lol.
Oh yeah, if you wax bathroom tiles with car wax (which is admittedly hard work) for the next six months ish you can hose them down with out scrubbing or cleaning and the dirt and limescale don't stick, so bathroom cleaning takes mintues rather than an hour!
IMHO there is a secret to ironing. Resign yourself to doing it, but don't think of a household chore, think aromatherapy steam treatment. Get some fragranced water (I know lavender is traditional, but I prefer violet) spray away and steam your clothes and you face in front of goood tv or the radio. As soon as its a beauty treatment rather than a chore it seems slightly less bad.
