Cleaning vinyl siding-Need help
Bought a house 2 years ago and a few years back they installed vinyl siding. I wanted to give the siding a good cleaning(used Murphys soap)and everything was going good until i got to the front of the house. Whatever I did I could not get the vinyl clean. The color of the siding is white and it has simulated wood grain and I can't get the dirt out. It almost looks like it's stained. I'm assuming since the front of the house faces downtown that it's the pollution in the air. I have tried the following hoping something would cut it: bleach,TPS,gas,simple green,any all purpose cleaner and finally laquer thinner. The thinner did cut it somewhat but theres no way it would clean out the small grooves and therefore it actually made it worse. I read somewhere where a steam pressure washer might do the trick. Would this work or should I try something else? Thanks for your help!
