Hi from New Zealand, the green country
Hi all, i am a tiler that has solved cleaning problems for a long time when it comes to tiles so with busted keens and a bad back i have started a business to clean them and concrete,
tiles i have no problems with
concrete on the other hand is a bit more of a mission when it comes to getting oil out. i have just got a contract to clean a 17 year old car park. i have a 4500psi hot water blaster and some great green cleaners. the chewing gum is not a problem except for the people that keep spitting it out.
the problem is the oil i can remove a good part of it but i would like to be able to remove more. i am open to any ideas.
any help will be gratefully received and i hope i can return the favor
