Cleaning cement mixer

[NathanSav]

Hi

I have a cement mixer on hire which I need to clean.

I go a concrete dissolver spray off the net, this works fine for the outside.

Is there a chemical/way I can get the hardened cement out the inside.

Thanks

Use water, lol. If it has stiffened in the sun a wee bit, chuck a shovel or two of aggregate in there and let it spin.

Was it there when you hired it? There are mortar cleaners, but these are for smudges and smears and not of any great thickness of mortar. They also encourage rust.

Half a dozen house bricks?

A few half bricks and some smaller stones with water and let the mixer turn for half hour.

I'll be that one who, when you ask for directions, says you shouldn't be starting from here.

Tip it into a wheelbarrow after mixing. Leave it so the paddles are at 3 and 9 o'clock, not top and bottom. If it's the last batch of the day then scrape it out with a trowel. Then it just needs a swill out with a hosepipe. If doing more the same day then leave the rinse slurry in the drum for the next batch, if not just tip it somewhere and rinse again.

Why the 3 and 9 thing?

Op is too late for that.

A mate of mine works at Jewsons in the tool hire. He cleans the mixers with industrial strength acid and gravel, running them for an hour or more. They get charged for the damage, and sometimes a new drum if it's been used for a resin drive.

I’ve never run mine for more than about 15 mins to clean, might try longer although if you saw it you’d see it’s probably past saving
It’s earned its money and then some though, got it 2nd hand nearly 15 years ago

So the paddles aren't in the puddle you'll end up with after swilling it out. Then you can wash them and they won't end up stodged up in the slop when it settles out.

I've put marker pen stripes on the outside of mine where they are so I know where I'm stopping it when I'm stood behind after tipping it out. You soon learn where it needs to be when you press stop so that it ends up where you want it.
