Vinyl sided house streaking

[gawashman]

Ok...It's about 97-100oF and we are washing a vinyl sided house. I hosed down one side to cool it off a bit and then applied chems shortly thereafter. Rinsed using my 0040 soap tip. Rinsed every layer of siding really well. As the house was drying water dripped from behind and brought dirt along. It dried quickly with the heat resulting in streaks. I took a napkin and wiped some of the streaks to shown that it was dirt and not damage from the chems. He thought it was chlorine damage. Heck the streaks came off if you rubbed your finger across it. I hand brushed one side of the house and rinsed again. Streaks were gone but new ones were forming. I told him that rain would eventually rinse these streaks away. The color of the siding was medium green. Now there has been some construction which would explain all the dirt trapped behind the siding panels. Some parts of the house do not have as much streaking. Very little for the matter.


My question is this--Is there anything that I can do to minimize the streaking. I used my soap tip to apply and rinse chems due to the high gable.

Sounds like you tried your best. Sometimes due to height, some moisture gets into the drain (?) holes on the bottom of the siding. I usually go back over the areas with a fine distant mist to rinse them off.
One time I had water run along some uneven siding under a porch and onto a radio, cost me $50.00 bucks because of poor siding install.

Happens every time I wash my own house. It doesnt last long, first rain or wind storm.

This is all to common when doing siding. Water and dirt leaks out from behind through the weep holes. It can be a real pain chasing after the leaks. I try to get what I can by lightly rinsing from the top down but Like everyone else said, eventually mama nature will rinse and get rid of it.

Thanks Larry. I did light brush it again and then took a wet rag and wiped it.

The high gable made it tough to rinse with anything other than my soap tip.

Weep holes suck. Try going at it from as far away and straight horizontal as possible so you dont bolw in under it too much. Weep holes happen to us too.Try an Xjet. That 0040is too much if the siding is loose and lets you get behind it. Or a 0540 or 1540

Arc

When spraying up at siding, you will do best to let your spray arc and act like the rain. This keeps you from shooting up and forcing water under the siding. With the proper cleaners being used, most of the work should be being done by the cleaner and not via pressure. So when soaping and rinsing, use of the natural way the siding works will help eliminate the problem you are encountering.

What I usually do is stand back and spray towards the siding, more like horizontal instead of up at it. If you are hitting it standing too close, you will get water up under the seams and it will drip out of the weep holes and there will probably be a lot of dirt/dust there that will leave dirt streaks.

Standing away from the house and shooting at it will lessen the chance of getting chems/water under the seams and dealing with the weep hole problems.

I agree, using the right soaps/detergents you will not need high pressure. The industry has evolved a lot from years ago where people just blasted everything with pressure, now it is about using the right soaps/chemicals to clean.

Everyone has their choice of chemicals they use and they have reasons why they prefer them. There are some good chemicals out there, read older posts on house washing or downstreaming and see what most people like or pm people if you want to know.

All vinyl siding has lapped seams. Generally, they run away from usual sight lines - ie away from a front door (in both directions). Spraying with the "grain" avoids pushing water behind the "joints".

what john said.you will have it happen.you just need to get you technique down to minimize it.i just go back by and mist it when i work back around the house.

Good advice chris.
