Retro-Brite (Sole Brite) Gel Formula : Restores Yellowed Plastic (16oz)

Works really well. I am using it to restore a bath tub in a mobile home that heavily yellowed over the years. I cannot put the tub outside so I have to treat it inside with Retro-brite and a UV light, which is not a super-fast process, but it is working well. For indoor use, I recommend that you get a 365nm black light with 50+ watts. I just apply the solution, cover it with plastic wrap (to keep it from drying) and hit it with the black light for a few days. Due to the size of the tub, I am doing it in small 2'x2' sections, but it is definitely improving the surface color substantially. There are a couple of spots on the tub that were not hit by the sun and never faded, and I am able to get the yellowed parts back to virtually the original light tan/putty color. Other than the restored color, the surface of the tub is not affected in any way by the product and there is no appreciable smell. Surprisingly effective but not a fast process and requires patience when using indoors.

It works as stated. I used it on my camper sinks and they are white again. Great product!!!

Wow! I used this (following the instructions exactly as written) to re-whiten/un-yellow some new-to-me, but heavily yellowed by someone else, white and light bluish-gray Lego parts. It not only met my expectations, but blew them away. Everything I used it on is back to like-new brightness. Next, I’ll be using it on some vintage Lego light gray crater baseplates and wings to get them looking good-as-new. Four stars only because the sprayer had to be squeezed so lightly so that it wouldn’t spray everywhere, it was a bit of a pain. Brushing it on is also an option, though. Highly recommended, though!

'Sure didn't work for me. Started out with such high hopes. 'Tried to remove yellowing on RV ceiling interior vent trim. Followed instructions, applied product, covered with clear plastic, sat out in sun.....Nothing....Repeated next day......Nothing. I mean absolutely nothing. Picked up some white plastic paint at hardware store. 2 coats. 5 minutes, looks like new.... I wasted $19.99 and two days on this stuff.

This worked great to clear some yellow on vintage transformers. At one point I did leave it on too long and it fades some of the colored plastic. Overall a great value.

So it didn’t completely take out the yellow but if I did it a second time it probably would. My Silhouette was on a table in front of a window. So it got yellowed in certain sections and when the cover was lifted it looked awful. I looked for something that would remove the yellow and found this. Super easy to use. I just put in on the areas that needed it, covered the area with seran wrap and placed it in the sun. The sun worked better than the led lights I bought to use with this, so you don’t need them at all. Just make sure the piece your cleaning is in the sun for a few hours. I did one whole afternoon and left it there without adding more solution and let it sit there the next afternoon as well. Looks great but I’ll probably do it one more time just to get rid of the last of the yellow.

This product did work somewhat, but didn't fully restore the color of the plastic piece I was working with.

Purchased this to brighten out a yellowing manufactured home tub & shower enclosure. Our home was built in 2012 and sold in 2013. It became ours in 2015. We keep a shower curtain partially close over the shower/tub but that front corner gets extra UV exposure from a window and had started to turn yellowy dingy. Though hubs did not notice, it bothered me and I searched for a fix. I put on a "rubber glove" on one hand and dipped my hand in the retrobrite tub and smoothed a thin layer over the area I wanted to brighten. I then wrapped it in saran wrap and put a grow light that I had on hand on it for 7 hours. The results were impressive to me. Next week when my husband is at work I will do up the front of the shower enclosure and inside the front of the tub where it also has taken on the yellow dinginess. So for tub areas that are yellow because of a UV chemical reaction on a 'plastic' tub. This product is a winner. It met my expectations and was worth the price paid. My shower, though not finished, looks cleaner already. It just makes me happier to look at it. I then was making cheesecake one day and notice my grandma's older hand mixer that I used was yellowing from sun exposure from our last house. I figured ... why not? I put a layer of retrobrite on, wrapped it in saran-wrap, put it in a ziplock bag and set it outside for 2 hours. It started to rain so I brought it inside and sat it under a UV light for 3 more hours. The results were crazy amazing! I get almost giddy when I see these results. It makes me want to find yellowing plastic just so I can try it some more. No regrets at all. OH! and no fumes to speak of and I am usually very sensitive to fumes. No issues when I accidentally got some on my hands.

Le processus a pris plus de temps que prévu. J’ai fait environ 5 séances de 6h, mais je suis très satisfait du résultat. Des puissantes lampes UV sont nécessaire si l’objet ne peut être mit au soleil.

Great item

Home Maintenance Project I had these terribly yellowed spa jets. Being the OCD individual I am, I sought solutions. Unfortunately I couldn’t get anyone to remove the jets and the manufacturer has disappeared into the abyss. So I’ve been searching for a solution other than ripping the bath out (which will happen eventually but not now). I found this product on I bought a UV LED light also on Amazon and grabbed a paint brush and some glad wrap. I should have rented a big UV LED light but I was worried it would damage the bath. I learnt that was a misconception. I would do that next time as it’s been a laborious job moving the little lamp around. It’s not a perfect finish for an OCD inclined personality but there is a significant improvement until I find where to rent the seriously Large UV LED light. So I’m feeling happier.
