Last weekend i did a pressure clean job on a shop front that was right on a main city road. The paintwork was very grubby from the usuall city grime, I wrongly assumed that pressure washing alone would remove it.
I ended up scrubbing the whole frontage down with various cleaners and then pressure cleaning that off. The job turned out well which was a relief as i thought at one point i was going to have to walk away from it.
My question is what chemicals do others use to remove city grime on paintwork.
The pressure washer i use is more than enough for most jobs and i have various lances and tips but nothing would shift this stuff.
I ended up using bleach and various liquid cleaners.
Any advice would be much appreciated.

What you need is to use a degreaser in the presure washer that will remove all the city grime because 98% of grime in the city is burnt oil  from exaust systems.

if theres a lot of oil soak it up first then use the soda if you've got a hot washes all the better

If the oil has penetrated the concret/brick then the deep staining will never be completly removed.

Absolutely correct. It is so much easier,quicker and cost-effective to replace blocks than messing about with acids,hot or cold washer detergents.As a rule contractors leave spare blocks with the homeowners on completion.
Denzle fyi bleach in its concentrated form is caustic soda so if you`re having trouble removing any stains be careful with this kind of stuff!

I would use TFR (traffic film remover) available in 25 litre drums. Glyn - Omnipole

Den
Try GUNK  you can buy it from most car accessorie shops ,ie : Halfords
that would most likely shift oil deposits

Hi keith.
that Oiltechnics link was very useful.
I've rung them and asked for info/prices for the removal of oil stains.
I will of course be asking for a 'free' sample to try out.
I'll keep you all posted if I get anything.
