Vinegar not working too well(concrete splatter)

[Striker]

Hey guys- i need a hand here.

I`m dealing with concrete splatter on my fox body mustang. This concrete has been on for decades (I`m guessing). For those who don`t know these cars- the bottom panels are coated with the rough texture (like rocker guard) so it is soft.

I`ve placed white vinegar over night on some paper towels and the next morning I tried to remove the concrete with my finger nails to little effect. Being the soft material, it has imbedded itself a bit into this textured finish.

There are four spots where this splatter is evident. Nothing massive but definitely want it gone.

Any products designed for this task??

kajunman`s suggestion oughta be just the thing!

Striker- FWIW, next time you want to use something acidic, I`d go for a decon. product instead of just vinegar. People *say* you can use vinegar for all sorts of stuff but it seldom works worth a [darn] for me.

Oh man do I love your Fox body....

I get cement on my trucks from time to time, If you cut muriatic acid 50/50 with water and dab it with a q tip it will break it down. Only need an ounce of each for little splatters. For larger splatters I wax by hand around the area without wiping it off and use a spray bottle with it in the shade and rinse off and wash. If it touches bare metal it will rust, but it doesnt react with anything like paint or roofing shingles, just dont let it dry on it obviously.

May not be true, but I heard sugar water (lots of sugar) will cut it.

Second the recommendation to muriatic acid (HCl).

Thanks brother. It`s coming along nicely (mechanically not necessarily paint wise) with adjustable suspension, control arms and all new bushings and steering components.

Tomorrow if the weather holds, I`m going to give it a light polish with 85rd and my PC just to spruce it up and then seal it.

Striker,
I`m in Canada too and my local Home Hardware brought in a couple of bottles of the Sakrete stuff for me. It worked extremely well.

Heh heh...you guys who use the HCL are keeping it off any bare/exposed aluminum, right? And chrome? My father loved using the stuff for bathroom cleanups until he trashed all the chromed fixtures...

Oh yeah, nothing on metal. I have a splatter of mortar on my dump body that im afraid to use acid on due the body being prone to rusting anyhow. Its only a year and a half old and has bubbles around some edges already.

I`ve performed concrete splatter removal on 100+ vehicles at a time using vinegar. However, my situation was much different and it was a fresh splatter, rather than setting up over time. The vinegar breaks down the lime and than it can be carefully washed away. The acid does work for more heavy duty situations but do be careful and if the wind is slightly moving, wear a mask for breathing and protect any visible skin. It burns like no other. Good Luck on your adventure. If it was me and before I chose the acid, I would saturate a microfiber towel with slightly ringing it out, placing over the area and placing something that had some weight to really let the vinegar absorb the area for a few hours

Yea the product I posted above barely worked. I still had to chop off most of it with my nails. I saturated a paper towel with it and it worked ok. I even used a pressure washer at point blank range and it didn`t do ````

There is no lime in concrete. Portland and aggregate.
