    Hello. Is it the standard blue chalk line? Is the deck presently unsealed? I would start with a gentle cleaner like Dawn dish detergent and a toothbrush go from there. If all else fails in extreme circumstances maybe a sanding will be needed.

    Aug 22, 2017 - Try an old fashioned red eraser & rub it just like you would a pencil line. If that doesn't work, try scrubbing w a diluted detergent & water mixture (as for dishwashing) & a toothbrush in a not to obvious place (near one of the beams) to get an idea give of how much the chalk has penetrated.

    You could try a Magic eraser or scrub using a hose and a stiff broom.

    If all else fails, renting a power washer for an hour or so may be your best option.

    I agree with soap and toothbrush. if that doesn't work, try lightly sanding. If that doesn't work, power washing.

    Try Awesome cleaner from the Dollar Store. It removes things no other cleaner will touch. Particularly good for things that have a texture to them as well. And the best part is it only costs $1.00. You will find a million uses for it.

    get a stiff brush and some hot water with a couple drops of blue dawn detergent and it should remove the chalk line - rinse and it is done

    Hello Sue,

    You could use a rubber or let it ware off or maybe wash it off with soapy water.

    Best of luck!

    Hi Sue: You could scrub it with some warm water and a bit of Dawn dish soap. Unless it's permanent chalk, then you can't remove that. :( If it's liquid chalk and the surface is smooth, you can use a magic eraser dipped in water. Good luck

    Apply a soapy mix of dishwashing liquid and then either pressure wash or use high pressure attachment for a hose. You might want to scrub first, you can use a broom to keep from bending.

    Thank you everyone. We tried power washing and Dawn detergent but it came down to sanding it off. Thank you all
