Hey guys,

My girlfriend and her mother washed their car with washing up liquid. I know this is very bad for the paint, I believe it strips off the protection. What can be done to repair the damage to the protection? Would a good wax treatment be enough?

Thanks for any advice.

Yep. Washing up liquid will take of most if not of any protection which was there.

Hopefully, putting a good quality wax will put some protection back on.

A coating of wax or sealant would sort that, I'd be tempted to go with something with a light polishing action too (say Auto Finesse Triple), as the chances are some swirl marks will have been introduced too.

Its not the end of the world and zaino recommend it as a starting point before applying their products as it does a good job of removing old wax etc prior to clay which will take off anything that was missed.

Don't make a habit of it and apply a coat of wax/polish afterwards, leave the Brillo pad in the kitchen though!

Washing up liquid is perfectly fine to use. It will just take all the wax off. It won't damage the clear coat or anything.

Doesn't it have a really high salt content? If so you are pouring all this nice salty water into all the hidden recesses / panels as well as the degreasing agents removing the wax protection...

Compared to road salt. Etc I imagine fairy has somewhere between zero and f-all salt content.

We did some tests at school on washing up liquids,most were around 20-23% salt.
That was twenty years ago though.

having used it myself there are fine salt particles like grit which cause swirls.

I'll make sure the car gets a very good hose down before we reapply a wax coating then.

This.
Periodically I will use washing up liquid as a stage two of a wash. Starting with a hose down/rinse to get the worst off then a washing up mix followed by hose down followed by proper car shampoo followed by another rinse.

There's no way the grit was salt, salt dissolves in water ...

yeah 1 teaspoon full if fairy of which only 25% is salt, diluted down into 5 gallons of water with that salt not suspended in solution like the dirt coming off the car but actually dissolved into the water at a molecular level, cant see that being very abrasive.

Far more likely its just the fairy took off the wax that was masking the scratches from previous washes.
