I don't know how useful these are for other people...

1. Save a couple used toothbrushes for cleaning tiny filter screens (like the ones in some washer filler hoses).
2. Like scrubbed new potatos? Ignore the soft 'vegetable brush' in the grocery store. Buy a small heavy duty scrub brush and make the job easy.
3. 2 to 1 water and vinegar cleans laminate floors better than the expensive stuff.
4. Double bag fish for the freezer = less freezer burn. (We get a lot of fish).
