This is my first house with vinyl siding and I thought cleaning it would be easy....boy was I wrong. Having tried every cleaner and chemical that I can think of it simply won't cut the brownish haze that is on the vinyl siding. Laquer thinner will cut it but you can't wipe it off fast enough. All it does is move the hazy dirt that is on there and you can where you tried to clean. Well today I borrowed a 1500 psi washer thinking that would surely help. Didn't even phase it one bit. So i'm going to call a professional and see what can be done. I remember a few years back we bought a new sink and we were having a hard time keeping it clean. We tried everything. Did some research and found out people were having good luck using "Bonami". We tried it and it literally made all the stains melt on the sink and all you had to do was wipe the sink clean with warm water. I'm hoping the professional will have a secret cleaner that will clean the vinyl siding. There has to be something out there.

try simple green or another product called purple power. each has chemical called 2-butoxyenthol that works great on many surfaces

I tried Simple Green and it does not work. Have even tried gasoline and it will cut it a little but for the most part the dirt is still there. Strangest thing i've ever seen. Will look into the purple power! Thanks for your help.

you or i should probably ask Bob at pressuretek, cause i didn't have any better results on vinyl siding today. used bleach/dawn/jomax/purple power/etoh. played with different ratios. still dark and dull!!??

how about a high powered steam cleaner it work well.

no way.. will warp the vinyl.

"Brownish haze" .. where is it? Towards the bottom of the house? If its what I think it is, the chemicals used/suggested are not the correct pH family.

Hot water would add to the damage done.Try Fantastik or Windex. For larger sections, a solution of vinegar (30%) and water (70%) might work on the streak marks.Be sure to spot check any general or stain specific cleaner before using it on a large section of siding. I think that would do it.

Leave the job to an experienced siding contractor, or at least consult one before putting chemicals on your home's exterior. Sometimes using certain things on your home's siding can cause even more damage, that won't go away. Getting advice from professionals in siding repair will make sure that you keep your home's exterior clean.

thanks for the list guys. it'll really help me.

Great advise from Pressure Pros

I'd advise using bleach and a good surfactant (soap) like Simple Cherry. If the brownish haze is what I think it is, it is probably rust or some sort of sap which you will need to wipe off by hand.

I don't use a power washer to clean vinyl siding. What I use is a poly-fiber brush like the ones used at self-service car washes, detergent from a dollar store, and a regular garden hose to rinse the detergent and weather from the siding.

You need go identify what your cleaning before you can properly clean it.
