Home made mold armor?

[Dieselhead]

anyone have a recipie for mold armor? It's a house/deck wash I believe is mostly bleach that does a great job at cleaning trex and wood siding. I believe Home Depot gets around $8 a gallon for it, surely it can't be anything special. I have my large deck to do and it's gonna take more then a couple gallons I'd like to make my own!

I see it works in 10. Minutes. Wouldn't it take longer to make something and probably cost more too?

Bleach does that. You can see the mold just fall off. It might actually bleach things though, lol, which doesn't mean that much to me since I like a light yellow house.
So, I do dilute it some for siding. But, I've used it full strength on a particularly moldy deck (in shade all the time).

My father used to use a concoction of bleach, Tri sodium phosphate (TSP) and tide detergent mixed with water in a 5 gallon bucket. I don't know the exact measurements though. Knowing his way of if a little is good than a lot is better it was probably a gallon of bleach, a box of TSP and a large container of tide dumped into the 5 gallon bucket and topped off with water.

I sprayed the bleach with a pump sprayer. Not that I'm bragging or anything...far from it. I'm not sure it did the screws any good.

Usually use about a 20% bleach solution with TSP, seems to work well for us.

a 6 pack of bleach at the wholesale club is pretty cheap! Small amounts of other ingredients can't be too costly, I need about 10 gallons of this stuff.

Good to hear, how much tsp per gallon?

For extreme situations, (or if you have a pool) you can use pool shock. This works great on siding and decks. Just don't over-do it.

Yep - the bleach, tsp and Tide works pretty well on decks as well as siding. I typically use a two gallon bucket and dump approx a cup of each into the mix of 1.5 -2.0 gallons of water. Let it sit for 5-10 minutes, maybe a little brush work if needed, then rinse off. For the record, I have first gen Trex for my deck and it is a pain in comparison to the newer version(s).

Think I usually toss about a cup per a gallon or somewhere around there in. I probably do it different every time, it's been a while, but I'm sure I read the directions then went the "more is better" route and did another 50% over whatever it said. Not that more really is better, sometimes, other times you're just wasting product or killing surrounding vegetation.

Of course, with all the above, EYE PROTECTION.

Thanks gentlemen I'll be giving this a shot.
