I've been in white coat and goggles this evening. OK, not really, but I have been trying my best to test Unicorn Power Scour as fairly as I can against my old standby, washing-up liquid (Ecover in my case). Power Scour claims to wash out dirt and grease more effectively, without yellowing and leaves the fibre with a clean, fresh aroma. OK....
I weighed two lots of 200g of nice greasy raw fleece as accurately as I could (one of Power Scour's claims is about yield on the grounds of reduced tangles). Each batch is to be washed in exactly the same way, the way that I normally do it:
- Gently lower the fleece into the hot soapy water. I've followed Power Scour's instructions to the letter, that is 5% of the weight of the fleece. That's 10g of product, which sounded a lot, but is really just a couple of squirts. (I weighed this carefully too, and used exactly the same amount of dish-washing liquid.) Leave to soak for 20mins.
- Carefully drain. lower into the first rinse water, which is the same temperature as the soapy water was when it was drained off.
- Repeat the rinse until clear. In the case of the Power Scour this was three times.
- Put into a pillow-case and use the washing machine's spin cycle.
- Allow to dry naturally.
The only comment I can make so far is that the Power Scour water smelled gorgeous!
The first batch (Power Scour) is done, and the second (washing-up-liquid) is brewing in the soapy water:
