good man 180

Tar remover didn't do a thing to it. I found wihite spirits do a better job!

I'll have to invest in some of this stuff.

Thanks

Apply bilberry using spray (diluted imo)

Allow to soak for 5 mins, then agitate the solution using a wet wheel brush to remove more stubborn dirt.

Rinse off

Job done! :)

And this will get off the tar thats seems stuck on there?

wash them first with the pressure washer, then use two bucket method like you do on the paint, apply billberry wheel cleaner, dilute it to your needs light soiled or heavy soiled leave for 2 to 3 minutes to soak in then agitate with a wheel brush, if that doesn't shift the dirt try tar remover or clay bar that should get rid of it, all these methods should work as it works for me.

If it doesnt I will be very surprised, I would start with diluted and then allow to soak rinse inspect what dirt is left and repeat however agiatate the solution with a brush.

Tar - Could always clay it?
