Plastics are yellowed. This is how I am getting them close to original.

My washer fluid and overflow plastics are yellow from years of UV light and heat. So I am going to try and convert them back to the off white like they were in the beginning. The photo of the underside shows where I am trying to reach colorwise. The process/product I am using come from groups that use it to convert old computers and videogames that have yellowed over the years.

Step one:
Clean them up as best you can. I used purple power and drill scrub head. Here is what it looks like after exterior cleaning only (my powerwasher broke so I cannot get all the gunk loose from the inside just yet)

Lay down some saran wrap in a PLUS formation and set the item inside. Then with a brush apply Salon care 40 Volume creme https://www.sallybeauty.com/hair-col.../SLNCAR63.html all over the yellowed item. Wrap it up and then put it out in the direct sunlight. Each day, you just open up the wrap, paint on a fresh coating and repeat. I have been doing the washer fluid reservoir for over 2 weeks (I forgot to take photos).

I just starting today on my overflow reservoir. I will add photo as this progresses.

Please share results when it's done! That's one of those whodathunkit types of processes.

Interesting. Is this a bleach based product or peroxide? It mentions something about a bleach booster but doesn't say it's bleach, or did I miss it.

Interested in this! I use 40 volume on my deer skulls for the European mounts. It's essentially a stronger peroxide than what you can get at the grocery store from what I understand. Who knew it could do magic on plastics as well

It is peroxide based according to the ingredients.

Here is the wiper reservoir. No before photos but it looked similar to the other but mostly contained on the top.

So after watching the video StoneTower posted, I dove in and bought the uv lights & 7% hydrogen peroxide. Wanted to test out the 2 methods. I am stopping the natural uv test on the overflow and going forward with the led lights. Will update once all parts arrive.

Found these on line. Stainless. Cheap. Had to get a little creative but both function and look nice.

Yes there are plenty of good aftermarket options but I am trying to bring back my jeep using the oem parts.

obsessive compulsive is what I call it. haha. It is the reason it is taking so long and no matter what, I will still not be satisfied. It will only be just a driver quality jeep with a rebuilt title. But I am learning a lot for someone who had no mechanical experience before this project.
