    Hi sirs,

    I have a bit of a dilemma. Let me tell you a quick story.
    I park my car near my office area. Just along the parking lot, a new building is being erected and falling debris from the ongoing construction can not be controlled easily.
    Here's the dilemma...
    I recently noticed that the exterior of my car developed these "white spots." I thought it was just normal dust and dirt that you tend to accumulate because of daily driving. When I finally had time to take my car to the car wash, the attendant who worked on my car said "hindi kaya ng hugas ung puti puti sir! mukhang natuyong semento na eh." I was not able to think of any other means that I got those spots other than the construction near my usual parking area. Anyway, I need some advice on how to have those "cement spots" removed. Is there a safe way to do so where the paint won't be significantly affected? What's the best cleaning solution to use? Is there a procedure I need to follow?

    Any feedback that you guys may have is going to be appreciated.

    Thanks! :D

    Bring it to a detailer and have a full exterior detailing job done. Do this immediately as time is not on your side.

    The same thing happened to me in 2008. I brought my Jazz to Big Bert's Julia Vargas and they used a lot of quick detailer spray and claybar work to remove the stuck-on concrete droplets. After an entire day at the shop, they got everything out. Half that time was spent on the concrete removal; the rest was for polish and wax work.

    I've had cement spots on my car for over a week I thought it was just mud. I hope my car's paint was not damaged. I still have spots that were not removed from washing!

    Possible ba na kainin ng cement yung paint?

    May 2 akong spot sa hood na hindi maalis. Binabaran ko ng nanosliq para lumambot. I cant distinguish kung wala na bang paint or matigas lang talaga yung cement. I rubbed it really hard but I could not take out those 2 spots.

    hi _c_, have you tried scraping them with your fingernails are they big spots? i have no personal experienced about cement spot removing but reading on some detailing forums says it can be remove using vinegar/water solution. put a tissue paper on top of the cement spot, spray with the vinegar/water mix till it get soaked then let it dwell for some time. give it a try, maybe it will help...

    Sirs, tuklap na ba o cement? Baka hindi lang cement tumalsik, pati bato. I'm waxing my car and these are the only two imperfections I saw.

    Thanks for the tip. I've been trying to scrape of with my fingernails but I still cannot remove it. Hindi ba mamumuti yung paint from the vinegar?

    I used polishing compound. Tumagos na nga yung init ng basahan sa kamay ko, ayaw pa rin I really hope hindi natunaw yung paint? I can't see it well kasi gabi na.

    di naman siguro mamuti yung paint as long as hindi sobrang tagal mababad. too bad if nag-etched na yung cement spot sa paint, baka di na kaya ng DIY lang and need na ng services ng professional detailers.
