Hi everyone

Does anyone have any tips on how to remove burnout marks from concrete?

Expecting landlord in a few days and wouldnt mind getting rid of a few blackies in the shed.

Try a wire brush. I just re painted the shed floor, much easier.

[Timd]

what sort of paint?

try a stuff called citro clean. it's available from coles

It will be near impossible to remove it completely. I rented a place before with a really stuffed up driveway. Everytime I drove up the driveway, my inside wheel would spin. After about 8 months, there was a pretty thick tyre track on the ground.

We tried petrol, kero, turps, everything. We tried scrubbing it with the chemicals mentioned above. We tried applying the above chemicals, then lighting them on fire. We tried using a gas cylinder as a flamer to try and burn it off.

While all these made it better, it was still quick noticeable.

Just paint over it and be done with it.

yeah ive had the same problem at a place i rented ages ago. i found using a wire brush and a heap of washing powder (nappy san or similar). Have ya tried a pressue washer/gurney, or HCL over the marks, if that doesnt work then ur probally screwed.

id use some type of acid to try and eat it away... youve been doing burnouts in your garage?

god. i read you post and i PMSL

anyhoo citroclean is agressive as. it removes polish off the floor so it should make a dent in it at least. try a few application of it to remove it. ie put it on and attack with a stiff brush, wait a little then put more on and attack it again.

anyone tried CLR?

if all else fails buy some grey paint lol

hydrochloric acid if you can get your hands on it then wire brush it.

Your local auto parts supplier should have a range of concrete cleaning products.

I used one a while ago, very caustic stuff, did a good job of removing oil stains, but I don't know how it would go with rubber. (I guess essentially they're the same compound?)

Hose the area, dump the powder on, scrub it, let it sit a bit, then hose it off.

But if you're going to use anything like that, suit up well.. it burned little pitted holes into my leather work boots.

Theoretically yeah, they're both hydrocarbons. Which means they should both react (to a certain extent) to other hydrocarbons, especially volatile liquid ones (kerosene or petroleum solvents).

God invented rental properties so that people could shit in their own backyard, then move along to the next place when the shit can is full

Be mindful with whatever you're using that it's possible that anything that would dissolve the rubber by making it softer is likely to sink into the concrete (especially if it's really porous).

Obviously if whatever you're using eats all of it away that's fine, but sometimes chemicals tend to do a half assed job.

alternatively... soak your tyres in diesel, then proceed to drive up and down the driveway evenly.

then give the landlord a bill for treating the driveway with waterproofing silicone.

[SKY031]

make sure any cleaners are rinsed off really well too.

It would be annoying to come out in the morning and find you have 4 tyres that have been eaten by concrete cleaner.

[funkymonkey]

are you allowed to flush that sorta shit down the drains (by rinsing the driveway) ?

[SKY031]

Only if the dude from the EPA isn't standing behind you.

i used to work at Golden Circle, and they got this stuff that'll burn the skin clean off your hands...

wen u squeeze the peel of an orange u get this acidic juice... they process the stuff into wat Golden Circle call "citrus oil"

if you can find that, u got no worries

[LBR33]

Use paint stripper that worked well for me....just dont let it touch your skin
