Hello everyone  I have a small problem l. I was cleaning my fence with a 2% mix and the fence now looks better but it's kinda white and if I scrub with a brush it seems to come off. Do you think it is a coating that is coming off? I am not the one who had this fence put up so I don't know if they put a coating on it or if its the pressure treatment that comes with the fence boards from home depot

Looks like there was some kind of sealer on it.

It is likely the pulpy wood,..caused by the bleach.

I'm not criticizing,.just stating what your dealing with.

If I were cleaning that fence I would have either DS'ed NAOH or applied Sodium Percarbonate at 8 OZ. per gallon direct,..and then neutralize with oxalic after either cleaner.

Did I use to much bleach? I have seen people use a bleach mix to clean fences.

 Always pre wet first and Brighten with OX last

You need to be careful with wood. From fences to doors, decks and even siding. Pre-wet to start then listen to those above. SH is not the end all be all and is only good for certain applications.

Time and experience will tell you what to clean so it's awesome that you learned this lesson on your own fence. What I would suggest is to do smaller areas next time. In other words.......do 1/4 of the fence and see how it comes out.....then adjust as needed.

I often cover a wood front door and hand clean with more appropriate cleaners. At times it's best to pre-wet, spray, then rinse rather quickly.

 Thanks for the input. Yea I only did one side of the fence and only about half of the side. It was also raining for 2 days so the fence was already soaked. Do you suggest I use sodium percarbonate?

I don't do that type of cleaning so I would defer your question back to those who do.

probably need to scrub, the dead layer of wood like Jeff said. definitly use a brightner (an acid like oxalic or critrus) to nuetralize the SH (a base).
percarb is the choice oxidizer for wood (basically creates hydrogen peroxide) followed by a brightner.if you dont put a finish on it, it'll turn grey again real fast. I mean weeks.

 

PS, Arts right, looks like sealer, better off with penetrating oil or a good sealer like Sikkens Cetol

Trent,

To learn how wood reacts to the various sodium based products. Find a dirty / nasty wood pallet that's been laying around somewhere. Take the pallet and divide it up into three sections. Before I go forward with this use PPE. Don't take chances. Use three pump up sprayers (each containing SH mix, sodium per carb mix and sod hydroxide mix). Apply each to a pre wet section of the pallet, penetrate, rinse and neutralize. For the record I got this from Everett Abrams. Look up his videos.

For the chemicals you have SH already. You can get the other sodium based products(F-8, F-10 and F-18) from Bob at Pressure Tek.

No. Do not mix chemicals with SH or with any others. These chems are to be mixed as per directions from the supplier with hot water. These are powders that will have to be mixed with hot water and possibly stirred thereafter. Each in the own labeled pump up sprayer(for now). F-10 and 18 are cleaners. F-8 is a neutralizer.

Going back to the pallet pre wet, spray one area with your SH mix, Spray one area with F-10 and one area with F-18. Rinse with plenty of water all areas after dwell time and then neutralizer all three areas with F-8.

Hank

 thank you for the reply.

so i still use the SH mix but use the F-10 and F-18 in pump up sprayers after i use  the SH mix. and then a F-8 to neutralize the chemicals.

No. Use your SH mix on 1/3rd of the pallet, F-10 on another 1/3rd and F-18 on the last 1/3rd. Rinse all three areas with water. Then apply neutralizer to all three areas. I have to ask this question...Have you cleaned any roofs or houses yet?

 oh sorry i misread the post about the pallet. the SH f-10 f-18 is 3 different chemicals. the f-8 is a neutralizer for all 3. no i haven't cleaned any houses or roofs yet
