If

you’ve

had

a

go

at

cleaning

your

patio

or

concrete

paving

slabs

using

DIY

methods,

you

may

be

dismayed

to

find

that

you

just

can’t

get

rid

of

the

black

lichens.

Black

lichen

is

very

stubborn

to

remove

due

to

it

rooting

into

the

surface

it

lives

on,

so

may

not

come

off

entirely,

even

with

commercial

cleaning

equipment,

but

can

often

be

improved.

Even

so-called

‘miracle’

chemicals

are

not

a

guarantee

of

complete

Black

Lichen

removal,

although

some

may

help.

This

is

one

reason

why

it’s

always

best

for

me

look

at

a

job

first,

so

that

I

can give the best advice and price.
