good video. I have used/tried all the products that are in the clip, and I will say, the spray pre-treaters are completely worthless.
There is 2 products that are in the video, that I do use and highly recommend using. 1 on them I have used to remove set-in stains that I thought I wouldn't be able ever get out.
1) Oxi-clean versatile. it is good for every load and does a good job at cleaning and some brightening. I do keep some on hand. But I have also found something better AND cheaper and has 5 enzymes in it, that is "Dirty Jobs" found at Walmart. I am keeping that on hand, I have been very happy with it.
2) Tide Ultra stain release liquid. Wow, this stuff is amazing! I use it as my pre-treater. It has removed set-in stains that other stuff wouldn't touch! I use it mostly on any colored fabrics, with no fear of lightened areas. I highly recommend it for getting out hard stains. It hasn't let me down yet! Give it a try!
Do use the warmest water possible, will clean much better than cool water.
