Had finished my week, so thought I'd do a dirty conserve job coz knew I could take my time and do a good job. Blimey, found it hard going and it didn't end up gleaming white after 3hrs of Tfr and scrub and rinsing as I thought
I only charged £25 as well :
, but she's an old customer and I used it to experiment, see how long it takes and idea of how much to charge for similar jobs.
Anybody had a similar problem with removing coal fire residue and detergents that work well on it?
Ta for any help, always appreciate it
