Ok so I did. House today, wood siding grey paint. Used1% from powdered bleach module, treated house approx. 1hr dwell time, rinsed with Bleach Wash through DPI module and then used bulk rinse to rinse entire house, i see patchy spots all over the house like powder, or the Bleach Wash was not distributed evenly. Tried to take pictures but you can't see it in the pics??

It's calcium residue. Try to find a SH supplier. No need to go thru all the headaches with ch.

a One hour dwell time is way too long. Maybe 10 -15 min tops on the real dirty side. Don't let dry on surface. On the other less dirty sides a couple minutes. No need to use CH on 1% solution mixes especially on decks and sidings. It takes too long to rinse, you almost have to brush/rinse. If it is a painted wood siding with smooth surface you can test rinse using a weak mixture of white vinegar and water maybe a cup per gallon of water. Spray then aggitate with soft brush and rinse. If you use CH it is easier if you use as augmented mix with SH when doing a roof. CH takes practice and I have found it is hard for my techs to use properly when I am not on the job.

Thanks guys, do you guys know how long CH is good for after its in solution? Have some left in tank and was wondering when it starts to weaken

It doesn't weaken any faster than SH. As you experiment on different surfaces, you will learn how to adjust strength as it starts cleaning.

Jeremy,
You cant allow SH or CH mixes to dry before rinsing. You need to clean a small zone at a time and rinse about 10 to 15 minutes or less. Rinse the last zone you treated before begining to treat the next.
