Hello It just seamed that our older powdered cleaner worked but nowadays there maybe a better way. So after some research I found the Pink Stuff and sold at Home Depot. It comes in Liquid and Paste. The paste is a little better for the tougher grime. Now the tools. Good 1. Basic setup see the 1st pic Pink Stuff liquid & paste with the Scrunge Sponge from Home Depot Better 2. Less expensive cordless drill setup DeWalt Brushless 20v Lithium Battery Ryobi Buffing & polishing drill attachment from Lowe’s The yellow and black foam pads work good. Medium cut blue compounding and buffing pad from Harbor Freight works better. (if 3” is out of stock the 5” pad can be cut to fit 3” polisher) Best 3. Professional orbit higher RPM polishing & buffing tool Central pneumatic 3” Air Polishing kit Summary The basic setup works well but may need some elbow grease. The less expensive setup takes a lot of the elbow grease out and works well. The Pro air buffer setup is less bulky and higher RPM just cuts the scum in a whiz! an electric or battery buffer should work well to, they are just heavier. See vid https://m.youtube.com/shorts/tkZdEPIOmjk?ra=m The bottom of the tub is non slip so the dirt and grime hid between the bumps. However after using this, it is all white as snow! Last 2 pics are before and after. Any tips on what you found that works well? Click on pics to Enlarge.
That is great information. The first mobile home we lived in when we got married had a fibreglass tub that over the years someone had used very harsh cleaner on it - probably Comet. There wasn't much left of the finish so it always looked dull. Using a buffer polisher and cut polish might have brought it back to life but I think it really needed refinishing. Years later, well after we sold the home and learned to do house repairs, I often though if I had known more about epoxy paints back then, I might have been able to refinish it.
