My experience (and by the smell), is that they are nothing more than
sodium hyprchlorite -- simple BLEACH. Just use that. I've used it in
both as a spray with my power washer (best strategy), or with a bonnet
scubber (for carpets). The issue is killing the algae off. I have found
that once a year does the trick nicely. The power washer (Karcher) is
the best investment I've ever made. Useful for all sorts of heavy

IIRC from my youth, there was a product called okite or okonite or something
like that that was primarily oxalic acid.
It is found in rhubarb. You can taste it. The leaves are trimmed in stores
to get rid of most of it.
It is what used to be a common chemical. With the DEA, liability problems,
and the general momma knows best Government, it is more difficult to get

Difficult? I would say easier than ever. It's on the shelf at the
retailers I mentioned.
The labeling of common chemicals with brand names that try to hide what is
in the product is more of a reason that things like oxalic acid *appear* to
have disappeared. You won't find a package of MSG in the grocery store,
but you will find Accent.

I do not deny that there are many chemicals out there disguised as home
products. You just need to know what is what.
For example, concentrated sulfuric acid is available as drain cleaner at
most hardware stores. As a chemical from a scientific supply house, it is
almost impossible to buy. Aside from charging a lot. In addition to ordinary
shipping costs, firms like UPS charges an extra $25 hazardous shipping
costs. Even so, a company Wilkem Scientific would not ship chemicals to me
personally because of liabilty. I was able to get a particular pH meter from
Wilkem not available from other suppliers because of DEA restrictions.

Oxalic acid is a wood bleach and is toxic-posinios. Requires special
I would not recommend it.
Go to a paint store they will carry a cleaner which I believe is
Sulphate or phosphate. They will know which. It is an exellent cleaner.
TSP was for many years the standard high octane cleaner. It worked
fine. But then the environmentalists decided it might be harmful and it
was removed from the market.
Oxalic acid is not as dangerous as the posters stated. It is the
active ingredient in "Bartenders' Friend" and "Stainless Steel Cleaner"
(spray). I use the latter to clean the permanganate ring on my toilets.

Now it might be that you live in the People's Republic of Leftcoastia or
some other workers' paradise in which trisodium phosphate is banned, but
that doesn't mean that the rest of us who live in the real world are so
Yep you can get sucked into buying the silicate
product if you don't carefully read the box.
Personally I think it is fraud to call the
silicate product TSP, design the box to look like
the actual TSP product, and then put "substitute"
in small letter. But, actual TSP is still sold.
OTOH, the silicate product (substitute TSP)
washes off more easily than TSP, but
it also clean a little less well than TSP. Take
Of course! It was never removed from the market,
but the amount of phosphate was reduced or
eliminated in many products a with concern for
increasing algae growth in many water ways.
Lowes, here, ran out at the time I needed some, so
they order some for me. Luckly I checked at a
local paint store and bought the same size box for
about $1 less.
