Hi Clinton
Not yet.
I have to fit it in next week, at the minute it looks like Wednesday all being well.
Just in the process of purchasing an Envirodri Gen4 to help with agitation of pre-spray on larger jobs, such as this. I will then also have the option of dry-cleaning for regular maintenance jobs.
Incidentally, I have cleaned a BW via HWE already. Just didn't realise. This was on a much smaller scale though; just hall stairs and landing on one of my early practice runs and results were good. Looks like the training courses are doing something right!
Looking forward to the challenge of this one and have all my crossable digits crossed!
I'll post when job done to let you know how it went.
