Best GRP cleaner?

[WestWittering]

The top sides on Flora are a bit the worse for wear after the summer. Lots of marks and scuffs, rubber marks, couple of rust stains, red wine (thanks to new boat dog), coffee (jibe), unexplained red marks (not blood)......

What would you recommend -apart from t-cut? Is there anything truly amazing out there?

I use Easy Clean, which I find works very well, though I assume I am being ripped off for some acid which I could buy for pennies elsewhere.

Thank you! Both get excellent reviews. I'll see which is in stock locally, failing that, Amazon.

Every mark/stain will have different characteristics, it may be hard to find a universal cleaner. Perhaps an abrasive type 'polish' on the bad marks/stains and an overall less abrasive one to 'ift' the overall appearance?

Oxalic acid, cheap to buy.Bought 1kg ,150 g makes a 1 litre soloution,so enough for 6 or 7 goes, applied with a sponge,wear protective gear,and leave for about 20mins.Then rinse off.Probably best applied on a dull day,makes a huge difference removes all the unwanted marks,grime and dirt,including any rust marks.
