I’ve got the teak pattern with black. The same one that DPVANDY posted pictures of. The only difference is mine has tan sunbrella around the edging and his has black.
I suspect that the foaming could possibly be due to a cleaning product or something since some experienced it and others don’t.
FWIW I just use plain old boat soap. The same stuff I use to wash the rest of the boat. Not sure if that matters.
