Caravan sitting on driveway is getting over-spray from reticulation and leaving water marks.

Is there a safe way of removing them without damaging the fiberglass.

Thought about CLR but it says not to use on plastic, so not sure about it.

Thanks in advance.

Edit...moving the van is not an option.

 Hi Des and Jayne,

There is a product on the market called "Marine Clean"

It is designed to be used on FRP as in the marine industry.

The main ingerdient in Marine Clean is Phosphoric Acid.

Phosphoric Acid will remove iron stains on most surfaces but read the label carefully and wear protective clothing gloves footwear and eyewear.... This product can be dangerous.

I have used it without incident for years and it is a great iron stain remover.

I tried CLR and phosphoric acid and none worked.
I used "Autosol'
It takes a long time rubbing it on with a cloth ... but it does work and is safe as I've used it on the caravan cladding to remove stubborn bore stains.
It comes up brilliant white again!

Hi,

I tried vinegar this morning, but did not touch these bore stains.

These are too old and stubborn.

Here is a pic during the Autosol cleaning compared to the untouched bore stains.

Have you tried soaking hand towel paper in vinegar, then covering with gladwrap & leaving overnight. 

Many years ago, I lived in Perth and, as was fairly common for Perth houses, we had a garden reticulation bore. I never found any product that would remove the orange (rust-like) bore water stains on the cream coloured house bricks, on the concrete paving and on the (so-called) asbestos fencing. And, I spoke with countless long term Perth residents who told that me removing bore water stains is impossible.

WOW! What a HUGE difference. 

Did it effect the silicone around that door in any way?

Try using a product called "Rust Off" availabe from Bunnings.

It is a concentrated Rust, Red Soil, & Bore Water stain remover.

Claims to be OK on most surfaces including gelcoat and fibreglass.

It is phosphoric acid based.

Hi whenarewethere and dougwe I'll stick with this auto-sol it has an immediate effect and when the area is done it looks factory again. It doesn't effect any sealant as its not applied to it only the cladding.

 Thanks Don. Have you tried it in black Checker Plate at all and how did it go?

 I have Autosol, great for cleaning stainless steel. This is a 30y old common laundry tub that no one gives a sh_t about.

Hello Dougwe,
I haven't used it on black checker plate but I know it will work on it.
This is a great product with many uses even though it's meant for metals.
I'm very glad I tried it on these old water bore stains, as nothing else touched it.

Nice job on the sink whenarewethere
