I never knew how little I knew about pressure washing before I met the guys over at cleaningtalk.com. They have a special mix for every situation.

What do you guys use when your prepping a house for a new paint job?

I used to use TSP, soap and bleach until I saw what the pros use.
...what do they use?

I worked for a company last summer that had a huge system in a truck
They used a lot of bleach, but I don't know what else (I didn't PW for them)
I assumed it was TSP/Soap

Premixed surfactants like Jomax but better. Some you have to add chlorine to and some you don't.

I ordered some Simple Cherry the other day, I'm looking forward to trying it out. You have to add chlorine to it.

There's a chem on this site called Limonene that I have heard good things about. I am not sure but I don't think you add Chlorine to the Limonene.

There are a lot more on those sites made for specific applications. Like the F-13 Gutter Grenade, for the oxidization on gutters.

Percabonate cleaners, strippers, brighteners, special oxalic acid mixes, etc.

I really don't know enough about it.

I use a mixture of JoMax(Zinsser product)+Clorox sprayed on home, then after 15 min. set time use pressure washer with various tips to clean it off, well.

Not trying to hijack the thread or anything but I did a search and couldn't find what to use if you want to wash a porch and not paint.
What doesn't ruin the sheen?

Bill really must not be feeling well. He'd usually be on a tear around here by now.
