What can you do with a ten minutes and about $1 (or so?) 
Make 12 quarts of laundry detergent
1 quart of *tub scrub
*Today I deviated from my “Rub a Dub 3 Men in the Tub Scrub” recipe and added Citric Acid instead of True Lemon (because that’s what I had) and added Bergamot essential oil drops (about 4) to make a nice citrusy smell.  Smells lovely! 
So easy I didn’t even have to get out of my PJ’s!
