Is there a cheap alternative to fungicidal wash?

Kernel_Sanders

I need to remove moss from a few bricks that I have to repaint and really don't need 5l of concentrated fungicide. I have a litre bottle of thin bleach that cost me 29p.....

Bleach in equal parts works so does vinegar but not as effective

Copper sulphate solution works best !

Moss isn't a fungus anyway

Kernal,
A jet washer will remove your moss and assuming you have one will cost nowt
You do have to take a step back and think WHY you are getting moss growing on your old brickwork?
Is it just minor and at very low level and what you would expect for an older property?
Or do you have a drive / path that has been laid a bit too high, or do you have a leaking gutter / rainwater pipe. If there is a lot of it this can be a sign that there may be a defect in your drainage

Cheap box of Supermarket Own Brand Biological Washing Power... mix with a bit of water into a Paste and spread over mossy or fungal area. Works a treat...
I did my front path with a good dusting of Biological Washing Powder, left it a couple of days and then washed/hard brushed off.... worked a treat...

You mean one part bleach to one of water? I think it may be that already as it's actually called 'thin bleach'. Should I just brush it on neat then?
Or maybe mix the thin bleach with cheap brown vinegar? I'll brush it off when dry and then probably go over again with the bio powder paste.
I don't have access to a pressure washer BTW.

That will produce hypochlorous acid a very weak bleach and mild disinfectant, I really don't recommend mixing chemicals randomly like that though some reactions are not so benign - at least 3 people I have worked with over the years have permanent damage from people mixing domestic cleaning products without knowing what they are doing.

Yes it doesn’t need to be strong enough to destroy all known life forms the cheap stuff one pint water one pint bleach etc should wipe it out does depend on the original strength but anything above 2% should kill it I’d soft scrub loose off first e.g. broom brush etc spray or paint leave overnight wash off repeat goggles and gloves would be handy same with vinegar one pint to one pint of water again depends on original strength

I used it neat; they call it 'thin bleach', for a reason, and sure enough it didn't fetch all of it off. I'll now go over it with the bio paste, but what viscosity are we talking about here, lemon curd or yoghurt?
