I was having trouble looking for non-or-least toxic ingredients for the wash. Finding a 'clean' laundry soap without toxic ingredients or heady scents that linger in clothing long after the laundry is difficult to find. So, when I came across this flat package of laundry sheets, I tried them. For my medium-size wash I used one sheet, tore it up into segments in the washer, placed the load on top of them, and started the machine. This was according to the instructions. After the washing and drying was done and removed, I was really chuffed to find the whites were whiter and the coloured looked much brighter than when they went in! When i bought the True Earth packet, I was delighted by their almost weightlessness; no heavy plastic containers to lift, or take up room for storage on the floor or shelf, or be recycled if possible, or worse, go into landfill. Judging by the results, I am going to continue with these laundry sheets, and hope they will make packs with far more than the 8 full sheets that can be split in half for 16 smaller washes. I recommend these True Earth sheets for their lightness and portability for travel as they take hardly any space in carry-ons! Best of all, I found them effective for a good, clean wash.
