Oxidized vinyl siding

I have a few questions for all you guys. When you are looking at a job and the home has oxidation how do you all go about explaining this to the customers? Would it be a good idea to have them sign a paper explaining you will not be held liable for sploching? Just trying to make sure I explain this issue to customers properly.

Just don’t wash it

I never had an issue with oxidation washing a customers home with low pressure so there has been no need to explaining it. I use 8 percent SH, elemonator, and water applied with low pressure. Low pressure is the key. However, I removed the oxidation from my own home once before by applying too much pressure to the house leaving streaks on the bottom half. I was rinsing with the high pressure x-jet nozzle and was chasing a wasp trying to hit it like an idiot. I dont do those kind of things when im cleaning a customers house of course. Anyhow, i just left alone for a few weeks and the sun oxidized the streaks back to looking the same before i began and now the side looks all the same. We had a hail storm and the hail hitting my house hard removed the oxidation and i had all these little spots about the size of a quarter. I mixed in a bucket a little bit of F-13 and water, soaked the house, and scrub the siding with a brush and rinsed. That helped quit a bit. It kinda of blended the oxidized spots in but still not a perfect fix. The only reason why i tried to remove them this time is because it was the front of my house. i will probably not apply a second time and just let the sun over time do its job again. You have to find a balance of what to tell a customer. I find if i give a lot of info about what may or may not happen then they are confused or ask about every little blemish that is on their house. After explaining different things to a customers about oxidation, shot gun fungus and list of other things, when i finished the customer took more notice to their home and asked if i had melted their siding. I said no, its impossible for me to melt the siding since i have a cold water only unit, and then i asked them if they had their gas grill there and they replied “oh, yes we used to cook on the grill often right in that spot where the siding is melted. Do you think the grill did it or could it been the sun and oxidation you were talking about?” i went with the grill. Questions like that are more often it when i try to educate them as much as i can. So i learned to find a balance and educate them on what they really need to know. Like if i see they have shot gun fungus or a loose piece of siding and so on. Hope this helps.

One last thing before i go and no offense IB but if just dont wash it was the answer then we wouldn’t be washing any ones home. Every house may have a different problem such as shot gun fungus, algae, mold, oxidation and so on. My advice is to get to know your equipment and chemicals and what they can do and not do. Start with low pressure and move it up as needed and keep asking questions like your doing now. Good luck!

Where did he mention “how” to clean it?

Soft wash and rinse with the soap tips. Stay back and don’t get up close. It’s all about low pressure. Don’t wipe or touch the siding with your hands or a rag. All of that prevents any issues with oxidation 99% of the time. Although, every now and then you might run into problems. It can be corrected by brushing that side of the house using a degreaser, gutter grenade, etc.

When bidding jobs do you check for oxidation and let the customer know prior to doing the job?

Absolutely
