I use it right out of the bottle...just be careful that you rinse it all out usually I will wash the white parts first then the rest of the body and then rinse everything to give it a couple minutes to work but it works awsome!!! Trust me you will be shocked!!! O almost forgot I use the liquid stuff!!
when your doing the tail don't be affraid to use alot you want to make it really soapy just be prepared to be rinsing for a while ha haha and good luck!
