Decking Advice SH?

Taking on my first decking job tomorrow, it's only a small area so it'll be good to try it out. Though I wanted to ask, are you using SH on decking or just using water? or any tips would be good. Thanks

Use a weak mix or it will turn it silver and take all the colour out of the wood .

If it was me personally i would clean with wide fan jet get it as clean as i can then come back once its dryed out and treat with a biocide im not agents hypo on wood as it does clean it very well but for me personally its biocide number 1 choice 

Or use sodium percarbonate and do no damage.
