Tiny black spots on Yellow Hypalon

[brucehawsker]

Loads of spots, some as big as a nail head, especially under the grab ropes and on the rear cones. 9 years old. Recently had cover cleaned and re-waterproofed.

Any ideas?

Thx

You could add more with a marker if you like them Bruce.

Sounds like Milldew.

Peterm had good result with bleaching them out of one of the ribs he did up!

I had the same problem. Same color tubes 10 years old. Found that "soft scrub" here in the states worked great. It's a thick bleach based kitchen cleaner

mould and mildew remover?

[brucehawsker]

Yeah, I think mildew is the answer. Bleach I had not thought of. Thank you. Any more ideas??
