What's something someone told you about that you thought to yourself "hmmm I dunno if that would really work" but tried it and it did work?
Mine for example:
I've always heard to use a cold wet wash cloth on furniture to remove pet hair and holy crap it works! I have no idea why but it does!!! I have a suede type futon that is black and my white cat sheds like no other and there is always a THICK layer of white fur on that couch that I can never get up.....but wipe it with a cold wet wash cloth then vacuum it all comes off!!!
Now what are your little secrets to things like this?
