fence cleaning

That is typically the main component of wood briteners. Some use blends in order to control the process a little more.
 
Yes like Mike said you will want to clean the wood first. You may use a stripping product if the fence has been previously stained if it is a raw wood you will want to use a percarb cleaner. Always neutralize with the ox as a second step to remove the alkalinity and brighten the wood.

How long is ox mix good for? Is it something that you can keep made up or does it need to be made at the time needed?

You can mix your brightener up anytime. It is the percarb cleaners that will exhaust themselves and should be mixed on the job.
 
Sodium Percarbonate scott....they call it oxygen bleach, just a good all purpose cleaner for unstained wood usually. Breaks down to oxygen, ash and water so environmentally friendly as well

doing a bit of a study on Sodium Percarbonate. I have a deck wash coming up. I see that a lot of threads talk of neutralizers. If So Per is a s friendly as it seems to be and it breaks down fairly readily why is it necessary to Neutralize it? Does just a good low pressure wash not suffice?

After cleaning decks/fences with sodium percarbonate I have rinsed with out using a brightener if the wood is not a dark color. Using a brightener will lighten the color of the wood and also give it a more uniform look.
 
Oxalic Acid Brighteners do more than just brighten wood, they neutralize iron and rust stains on wood as well as open the pores/cells of the wood so that your coating will get better penetration as well. This principle also works with concrete where by removing metal and tannins stains as well as prepping the concrete for staining/dying as well. For concrete there are other acids as well.
 
did that deck wash yesterday. awesome result. customer happy as. So Per looks really impressive when it foams up. How do you guys get on if your customer is not home, with regards to hot water to dissolve the SoPer.? Just looking ahead to the time when I can't get hot water on the job.

Found an answer for myself but still interested in how you guys deal with this issue. this is what I found. {Mixing Solutions of Sodium Percarbonate. Sodium Percarbonate solutions will remain active for 5 to 6 hours, after which they should be discarded. Unused material may be poured down the drain. It will actually help clean and deodorize your disposal or toilet. Sodium Percarbonate solutions are most effective when mixed and used in warm to hot solutions (100 to 150 F)}. Gong by this I could premix at home and take it with me but of course it will loose the temperature. Can I compensate with a little more SoPer.?
 
No wrong!!! Do not pre-mix and store under pressure as it will blow in your van or vehicle. If anything take warm water in your sprayer or in extra buckets to the job and then mix on site. I usually tell folks 6-8 hours on it being active, either way it is a short shelf life. Same thing returning home do not leave the percarbonate bleach solution stored under pressure.

Cheers Everett. That's the sort of feed back I was looking for. Thanks very much most appreciated. Stuart
 
If you have a hot water unit you could always kick it on to mix the precarb.
