I have tried the scrubba at home to perfect the technique (which I would recommend doing). I used liquid detergent to try and get the quantity right but I couldn't get it consistent. I needed something that was as portable and easy like the scrubba. I found detergent sheets from woolworths, they say only use 1 or 2, I have used 4 sheets for my most smelly clothes, the other trick I have learned is to soak the clothes, I found if I agitated the bag for 2 minutes then let it soak/stand for 5 - 8 mins then agitate for a further 3 min works perfect for the worst of smells. I have also washed jeans and the scrubba works well. Very happy with this product. Well done
