Started softwashIng a deck today and the soft wash just isn't working . So I went and started pressure washing it (old school).
But the wood is still holding black marks. Here is the spots I'm talking about. And another picture of the deck when it's dry. Plain wood as far as I can tell. No stain no nothing.
The first picture looks like "garage" type grease spots? The second picture looks like it hasn't been done yet?
What is your chemical choice on the second picture?
The first picture looks like it's gonna be tough,..because I just don't think that's mold or regular dirt.

I'm using a deck wash from EMS and 4% sh. Yes the 2nd picture was not done yet, was just showing what the wood looked like.
First picture is by the back door, and I don't have a clue what the black spots are.

Almost looks as if the grill was there at some point.

Not a whole lot of choices on those black spots. If it were me,..I'd lay down some degreaser like Purple Power and let it dwell for about 15 minutes and then hit it with medium pressure and see if any at all comes up. That isn't typical deck cleaning. Ask the owner of the deck if they can give some insight as to what it may be,..knowing what you're dealing with in this business is the biggest part in knowing how to deal with it. Maybe a stiff bristled deck brush to work at those spots would help,..likely when this is done,.it will need sanded,.and then even a medium colored stain to help hide the remnants of the cleaning.
Second picture,..Sodium Hydroxide 8 OZ. per gallon,..DS'ed and then rinsed away,..and then use oxalic acid mixed about 12 OZ. per gallon and DS'ed And it will be good. Or Sodium Percarbonate mixed about 8 OZ. per gallon and applied direct and neutralized like above mentioned with oxalic.

Can you buy,..Sodium Hydroxide in town? Or is the something else I need to order?
Jeff Wible said
Jun 6, 2016
Sodium Hydroxide is the same as old fashioned "Lye". You can buy it at hardware stores in the drain cleaner isle. Ace has a brand called "Rooto",..It comes in 1 LB. bottles.
Mix it with some soap for dwell time.

How about the oxalic acid ?
Jeff Wible said
Jun 6, 2016
By the way,..you REALLY, REALLY,..need to learn these products and how they react with each other. Never mix anything you're not sure about.
Sodium Hydroxide gets very hot when mixed with water at the ratio I mentioned. Now,.this is where things get touchy on these boards.
Be VERY careful and wear appropriate gear when mixing.

You need to find a local chemical supplier for many of the things we use and recommend. Sometimes oxalic is sold in hardware stores as wood bleach,..I never seen it,.but I've seen it mentioned many times over the years.
I know many of us use Univar as our supplier. So look them up.

I sent them a text a few minutes ago asking them to check in. Perhaps they are busy and let's hope they are ok with the recent storm.

The other thing you will need is a good gutter cleaner. I use and prefer Purple Power,..easily found at Walmart,.although I order from Advance Auto.
Never heard of that company. Mainly you need a source for 12.5% Sodium Hypochlorite,..many pool supplies have it on hand.
Jeff
Ox acid is very common and is the wood "brightener " I posted, will get out those black marks, need to dwell but not dry.scrub.
You should have a Sherwin Williamso near you, they carry Duck back super deck REVIVE, they are great to work with.
