Ok chaps, couple of peeps have asked about using Bio washing detergent on 1st cleans.
It works very very well. Better than anything else you will ever use. Your brush will be spotless too. I mean actually white like the moon. And it's cheap a box of Bio powder a couple of quid, I charge a premium for Bio washing also.
You see the majority of the muck is biological matter, Bio washing power will completely digest and remove the matter leaving it as new.
This is the moment those who spent lots of money on soft washing systems go the way of the people on the purple bricks adverts.....
Anyway...Back to work
