Is there any way to fix this?

hello, i recently did a pressure wash on a aluminum home. i got all the dirt and grime and residue off the siding but when it dried, it left streaks and some of the siding was darker than other areas. i didnt use any chemicals because the siding didnt seem to be that dirty. IS THERE ANY WAY TO FIX THIS? i really would appreciate any help here, thanx

Oxidation. NEVER use pressure on oxidized aluminum. Please read about down streaming. It will save you time/money/insurance claims. I'm guessing you will need to brush on f13 or something of the sort. Also you will need to fill out your signature.

Images like these bother me... Especially from a professional.

I always am leery of aluminum siding. Each house reacts differently depending on level of oxidation level and age of siding. I usually go with a good alkaline soap, warm water and low pressure. Looks like you might be doing some brushing. Good luck

So to be clear, i hear you saying that the streaks are can be removed but it will take some time and effort.

Ok,..I see no signature of any kind,..not sure if you're a business or a handyman or a broke college student or what,..but if this is a service you're wanting to start,..you really need to get a better game plan than you displayed here. So,..I'm gonna address this as if you are doing this as a service.

Definitely oxidation. On a positive note, to me the paint looks to be in good enough condition to tie it all together and have a decent result. Yes,..it will take some effort,..and these dark colors are the worst at getting correct. You need a cleaner like Purple Power or something similar,..apply it very evenly with a pump sprayer,..and brush it all. The PP will make the oxidation loosen up and run off alot on its own,..especially if it's nice and warm or even hot out. Start with a mix of 50/50 PP to water. But that siding looks like it will take full strength,..and ALWAYS do a test spot to make sure the paint will handle the cleaning method. Worst case scenario is you'll have to clean it the way I mentioned,..and you will still end up with a customer who wants a paint job.

*That looks terrible,..When washing anything,..you have to use detergents for the job at hand. Doing any exterior cleaning without proper detergents is NOT the professional way. This really is what gives this service a bad reputation, and many people who are potential customers look at this kind of thing and think we're all the same.

**A skill that is REALLY needed in this business isn't only how to clean,..but how to evaluate. And that job needed better evaluation.

i actually went over it again using some krud kutter and a brush. i got rid of most of the dark spots and the pressure washer marks look a little better. i was thinking of using everbrite to bring the color back but i wanted to know if using that will cover the streaks and marks if they arent that bad. what do you guys think.

What I would do is read Jeff's post and when ur finished read it again.

Your in the Northeast like me. Old Alum siding is common..If you can run your finger across it and get any chalk on your fingers consider that a danger sign

My advice is just stay away from them. I used to have a waiver form advising the client that the finish may produce an uneven streaky finish..

I stopped doing that and just decided not to do them at all..Too much other stuff to do

Unless I'm prepping it for painting it afterwards its just to much potential trouble..

All you had to do would have come on here an ask first how to properly clean this.Instead you went at it with the totally wrong method of cleaning.Ds meduim mix on it an let dwell do a very light rinse an you would have been great.
