I bought this product for use with my Spear and Jackson pressure washer and cheap Ali express snow foam lance. I have used it to clean cars, the conservatory and wheelie bins. The soap works very well and it has a nice smell. Initially I couldn't get the foaming effect I was looking for so was left a bit disappointed, however after a bit of experimentation with the flow, the nozzle and the amount of foam in the bottle I finally achieved the foam effect I was after. I have had a slightly different approach to other users in that I have foamed the car, left it for 5 to 10 mins then agitated the foam with a wash mitten then jet washed off leaving the car perfectly clean. It is worth noting that none of our family cars are black, so I would imagine using the above method would leave some swirl marks on the paintwork on a black car. All in all I'm happy with the product and will buy again if the price point remains the same.
