How to remove concrete residue from plastic

[Ignoramus20184]

I have a couple of those

They have white concrete on them, some solidly stuck. How can I remove
it safely to restore the good looks. Thanks

The most "safe" and expensive way is to use a liquid product called
"Concrete Blaster":

Designed specifically to remove cured concrete from construction
equipment.

Might be a bit tricky to use on your saws.

I'd soak a towel in the stuff and then wrap the towel around the saws.

That stuff is moderately expensive.

If you're more adventurous, I'd use muriatic acid (Home Despot sells it
by the gallon last time I checked). Cut it 50-50 (or more) with water -
and then use the towel method.

But keep it away from any shiny metal, because the acid will take the
finish off.

It's best if you can remove all the plastic parts and dunk them by
themselves into the acid.

Any non-shiny metal parts that have dried concrete on them can be dunked
in acid - just don't let them sit in the acid for a long time (more than
10 minutes).

If you use muriatic acid, wear a good filter-mask (with cartriges)
because the fumes will sting your nose.

Can you get the plastic covers off? If so, just leave them
in a bucket of water with a little vinegar in it. I guess
a LITTLE muriatic acid would do the same. Soaking in even
mild acid over time turns concrete into mush.

Looks like a thin layer on the covers. Perhaps a few times in and out of a
freezer will let the plastic and concrete expand at different rates,
getting it to loosen. A few sharp taps on a concrete floor and you're done
...
Maybe ...

I will try this, preferably with vinegar. Muriatic acid makes
everything near it rust.

DILUTE muriatic acid (10%) or vinegar will work, Ig.
Adding 1 cup of acid to one gallon of water is 1:16 ratio, but it also
works. Gallons of muriatic cost $4 at stores, or borrow some from a
friend with a swimming pool. He won't need it this winter. ;)

Buy a gallon (or more). It can help you clean your slab in the new
warehouse. http://goo.gl/98YzV

Others have suggested acid, but thats probably not concrete that set in
place. Thats a concrete wet saw, so the white stuff is just dust from old
concrete that dried on. I bet warm soapy water and a nylon brush will take
that right off. A little vinegar couldn't hurt.

You cant. Name of the game.

Bead blasting will clean up the mental..but etch the plastic. Soda
blasting might clean the plastic..but wont touch the metal

Unless there is a process Im not aware of. Now...have you tried a
pressure washer? That may simply be caked on concrete Dust rather than
dried concrete thats set on the saw.

its a commercially used tool, it needs to look decent, but doesnt need
to look brand new.......

if your reselling it you might price new covers

Why don't you read what others have posted here on the subject before
you put your foot in your mouth?

That looks like a TS400, they are very popular amongst contractors,
and easy to repair and get parts for. I would try washing it with hot
soapy water first because it could be the splash from wet cutting. If
not, it wouldn't be difficult to remove the covers and soak them in
acid. Those saws average around $400.00 on ebay in good condition.

Why dont you read the last bit of my post..and why did you snip it off?

Either you are an idiot, or have some sort of score to settle. Not sure
what it is..perhaps you are another one of the Far Leftwing Extremist
Fringe Kooks I tend to bash rather handily?

Or did you..as a mental case..not read the last bit of my post..about
the pressure washer..and didnt quote it in your delusions?

Gunner who responds to posts as he comes to them..and doesnt bother with
waiting for a group concensus.

Because it wasn't relavent to my observation of your posting style.

Which is less practical or efficient than reading the entire thread as
it currently exists before posting your contribution to it.

> and doesnt bother with waiting for a group concensus.

A consensus hardly ever develops from extended threads. So that point
of yours is unfounded.

Oxalic acid (component of automotive radiator flush) is a far more
effective acid for projects like this than vinegar, but not as brutal
as muriatic. Haven't tried it for precisely this sort of thing, but it
might be pretty good, worth a try and cheap, too.

Blink blink...so you were indeed bitching about me, and not what I
wrote.

Sorry numbnuts..but I simply dont care what you blither about. Dont like
my posts? Use the handy killfile and be done with it.

Now about my commenting on the pressure washer....???

You are really a dolt.

Sigh...
