Some good cheap tips here. I have always used vinegar as a fabric softener, (no, there's no smell once the clothes are dry) and as scale remover. It's a good disinfectant too and it cleans stained aluminium. Put a bit in the water when you're washing windows and bling bling, their sparkling shiny and clean. Good for cutting through the muck on car windscreens too. Uhm... what else?
Oh yeah, it's really, really cheap, non-toxic, pet- and child friendly, environmentally harmless and good for your health too.

10 Health Benefits of Vinegar

Grandma knew that her old remedies worked even if she couldn't explain to the scientific world. She knew that diluting vinegar in the ear would help infections due to swimmer's ear. Now, the American Academy of Otolaryngology endorses this remedy. There's something to be said about how smart grandma was.

Also great for cleaning the salt/mineral build up in jugs, water coolers.
I love it as an air freshener because it reminds me of mum making a pavlova ( for which it is an essential ingredient.)

Also, if you rinse new dark clothes in strong vinegar water before you wash them the first time, the colours stay in better and the clothes don't fade as fast.

I love Pavlova, btw.

Works great also for itchy scalp. I use a spray bottle of apple cider vinegar about twice a month for dry itchy scalp. Works like a charm when nothing else would.
