Bonjour Gilles

sorry to hear of your misfortune on the original tarp.

No doubt the pressure washer has removed some old caked in dirt in some places more than other paces and has left streaks...... so you have some light colored fabic fibers.....

I would try to wash it again.... at lower pressure..... get it wet...... rub in a mild detergent...Liquid Ivory.......soft floor brush by hand....... rinse with the pressure washer in one direction and again at 90 degrees to the first rinse...... you may be able to blend in the streaks enough to make it useful again.

It may help to hang the tarp folded over a rope line and wash from the bottom up and rinse from the bottom up....... instructions from pressure washer manufacturers always strongly recommend washing from the bottom up with a pressure washer as it will allow to flow dirt from the upper part over the cleaned section of the lower sections....... other wise the soap solution will streak on the lower part of the tarp that has not yet been washed and may be very hard to remove....they say the same for washing house sidings or vehicles......

Cleaning a tarp is like removing the patina from an old piece of furniture... it is never the same again and usually reduces its value......

Once the tarp is very very dry you may have to use some waterproof coating available in camping supply stores.

Good luck...... and let us know how you made out...
