Cedar Siding

What stripper do you use for the cedar strip/wash … anything in particular that i should look for ?

My son and I started a power wash business 2 years ago. There are hundreds of log cabins in our area and we’d like to become an expert like you. We’re quoting a cedar siding job & wood restoration is a bit scary to us. We have a Power Line trailer with xjet (heated) and use 5 gallon buckets. After hours of researching wood strippers we still need guidance. Do you use DSR-50 for the cleaning? What mixture would you recommend when using oxalic acid? Do you use the powder form? Any help would be greatly appreciated!!
