My carrara white C2S is not as white as before. One can notice the difference when you open the door and see the parts not exposed to the outside. Griots polish, clay bar and rejex were the treatments. I used griots best of show wax before which i think affected the color. Is this possible? How can i get the whiteness back? Ideas from detailing specialists?

 

I would use detergent or chlorine.

scrub it in real good with a brillo pad while you're at it.

 

Posr this on autogeek.net , on the forum. They will square you away.

 

I have heard if you have wax down and then use certain silicone waxes over it that it can cause the wax trapped underneath to yellow. If that s the case then you need to strip down all the waxes. You will need to try small sample areas to see what type of cleaner works. Remember you don t need to be abrasive on the paint, just the wax products that may be dis coloring the appearance of the paint.

 

Don t laugh but I d try a little Kerosene on a soft cloth in a small spot. It will not harm the paint and is a good cleaner of petroleum based debris.

 

Cerbomark, in have used kerosene on some of my older cars and you are absolutely right that it removes asphalt splatter with ease. No laughing here. Te story is i used griots best of show which is brown in color. I felt it stained my white finish. I tried to remove by using grots clay, griots machine polish 3 with polisher set at 5, then a coat of rejex. Of course with washing in between steps. Fnish is very good and very smooth. It just when i open the doors and see the unexposed paint, it seems whiter than the outside exposed areas.

 

well if you know when it stained and from what product then I would get in touch with the company and see if they will help. It appears you have made some attempts already to remove the stain. Keep us posted.

 

Put some chlorine on a rag, that's what I use to get tar and tree mold off some of my cars.
Works great, try a small spot first to see if it brings the color back up.

 

I hate most of griot's stuff especially the best in show wax. The wheel cleaners are sorta ok and they do have some handy gadgets to make cleaning easier, but I never use their wax or sealants.

Strip waxes and sealants using dawn and water or chemical guys citrus wash and gloss 1 oz to 1 gallon dilution then use iron x to decontaminate the car from iron particles, then clay your car, then use menzerna polishes to bring back the shine and gloss and top with a wax or sealant. Or you could try p21 paintwork cleanser instead of polishing if you don't have access to a polisher and see if that will be enough. If it still looks a little dirty then you will have to machine polish your car.

Do not use an IPA solution if you have a clear bra!

 

I would estimate that your exterior paint has been more vulnerable to the elements than your interior paint. Sun damage will affect your paint over time. What year is your C2S? Have you tried claying back to back passes?

 

I just felt it was stained by best of show wax. I might be wrong but im never going to use that product on my white car again. The environment might also be the cause. Year is 2010. In a span of 3 years i do notice that environment has yellowed 2 sets of stone guards.
Thanks hakaida for suggest, i will try to get hold of p21 cleaner though i have already used griots machine polish with their own polisher set at 5.

 

Who'd laugh? Kerosene is a petroleum derivative (the exact nature of which is too complicated to get into and besides the point) and it may be classified as an aliphatic hydrocarbon. As such it works well as a solvent for oils, tar, waxes, etc. There are, however, better solvents and kerosene is rather heavy and may leave a bit of greasy residue. (Personally, I favor a gentle application of WD40 - if for no other reason, the smell isn't as bad.)

 

Dawn dishwashing detergent will strip all the old wax. Just put in water and wash as you normally would.

 

Second vote for Chemical Guys Citrus wash. I have used it on three different vehicles when I wanted to start fresh.

Citrus Wash, clay, and polish a small section and that should do the trick.
