this recent weather has caused dribblings deep down to the basement of the car park where I keep my beloved Elise. It's dripped basically calcified water all over the back of it, leaving a stubborn white limescale residue. A wash and polish won't shift it. I was thinking Calgon or similar might?

any experience of this or similar?

if so how did you get it off?

any help much appreciated before i plaster my car with something that might make it a lot worse!

I wouldn't want to venture down the calgon etc route as that kind of stuff is designed to clean stainless washing machine drums and not nicely painted fibreglass..

I'd go for the least invasive stuff possible.. What about one of the Autoglym products for removing heavy road tar etc? That may be a better starting point IMO.

Yes, or Autogylm Paint Renovator. My brother let cats run all over my car when I was abroad for a few months - nearly brought me to tears seeing all the etched water/piss marks on the paintwork.

The vinegar helped, then Autoglym removed the stains completely. Phew!

On no account use "Kilrock". This stuff actually works and removes (in a hot minute) any limescale you may have on practically anything. Bogs, sinks, work surfaces, kettles etc.

It would be, however, WAAAY too strong to use on your P&Js paintwork. Autoglym and some elbow grease would seem the way forward...

many thanks, I was eyeing some cheapo brand of limescale remover in Lidl yesterday, I reckon that would have taken the stripped the 'midnight blue pearlescent' off in seconds!

the only reason I mentioned calgon is that I thought it used a chemical reaction to dissolve the calcium (ie shouldn't affect the paint) as opposed to the Lidl stuff that was basically just acid! Looks like wishful thinking!

cheers

I think the chemical reaction is basically acid!

As said, if Autoglym paint renovator or T-Cut (which is more agressive) doesn't get it off then it might need a machine polish!

+1, it's even better hot (but not boiling, no need to strip the wax off!)

I have used a bathroom limescale remover called Limelight. It's designed for use on plastic baths. I have used it on my fibreglass bath and it worked. Sainsburys have it.

As said above , you need an acid based product to re-dissolve the solid minerals that cause the limescale. Obviously you don't want to use anything too strong on your car so household vinegar (acetic acid) will probably work fine, but just take a little longer. Better that than strip the car down to bare fibreglass though!

Many thanks to all who helped. White wine vinegar when applied to a car washing brush did the trick. Pride an joy is now back to her best. In fact it looked so good after a good wash that I felt the need to take it out and get it dirty again!
You have no idea of the relief of seeing that crud come off!

A scratch removing product will break it down. I used McGuiars (sp) Scratch x.0
