Re: Getting dirt out of Collinite paste wax
Im from E Penna. where the coal is 'hard' and all the mills were closed down by the EPA pressure, I dont know about soft coal dust. ;-)
Here's a test.
Put a few drops of strong ammonia or TriSodiumPhosphate (TSP) solution on these specs on a horizontal location on your boat, immediately cover with saran wrap and tape the edges to the FRG gel coat. Come back in a few hours and if the specs are now 'smeared' or even dissolved = a fungus, probably artillery fungus. If you dont have strong ammonia, than any 'strong industrial grade' caustic detergent will work.
