The “stuff” the professionals use is essentially household soap. Don’t use washing up liquid it’s got lots of salt in it, keep all the heel ends of your bathroom soap bars, mix with a little water and let it go soft. Alternatively you can buy the real stuff quite cheaply. I got a tub of it 20 years ago still got most of it left.
