Whitening and/or cleaning coolant overflow bottle / reservior ?

[suprarx7nut]

Anybody have a tip or trick to getting the overflow bottle, brand spanking new and white? I picked up a pretty clean one at a junk yard and want to make it absolutely white as can be. My current bottle is ok, but its not white or new looking. Now I have one I can take my time with off the car.

Any solvent that works well? I've tried plain water, water with a little bleach and no change was apparent. I dont want to ruin the sensor, but I would love the bottle to be shining white!

Thanks!

I was wondering the same for myself, but only my problem is worse. I have black, soft, gooey stuff in the bottle, I wonder what that is.:3d_frown:

You can get it pretty clean, but the yellowing is age/heat/UV and the only way to fix it is to replace it in my experience...

After buying a car with a BHG, I cleaned the junk out of it with strait Simple Green cleaner, and a few marbles.
After putting a few ounces in, and the marbles, I shook the crap out of it.
(pun intended)

ultrasonic cleaning bath with industrial detergent cleaner (Alconox) is the only thing that got mine clean.

Bleach it I did it doesn't make it 100% but it works well. just fill it with thick bleach and leave overnight. then rinse well. and repeat if required.

Would anyone reccommend soaking it in Purple Power? Or is the bleach route much safer?

Most anything has a chance of attacking the seals and the bottle itself. It's just the nature of the plastic...

I have cleaned mine using both simple green and purple cleaner. I get an old wire coat hanger and bob it on one end with a rag wrapped or tapped around it.

Kind of funny seeing you post this up Sparky...

How about peroxide?

I sprayed the inside of mine with purple power and let it sit for a couple minutes. Used a green "scratch pad" type of thing to scrub the outside. Looked fairly good.

The best thing i've found is to put a load of rice in and some soapy water and then shake it. The hard rice is quite sharp and gets into all the corners nicly. I used this method on a car which had a BHG and it got all the oil out.

I don't know if it works, but I had to post the picture.

^ truth. Cheap plastic distorts and changes color with age.

Need a white bottle?

Step 1: Remove 7M
Step 2: Install decent engine
Step 3: Install new bottle
