I use CLR to clean the bathroom and it works well, the bottle says it's safe for fiberglass.

I like CLR too, but it seems to me that its effectiveness (especially against rust) has been reduced since they had to take the phosphorous out of the formula.

Of course, removal of phosphorous from cleaning supplies has long been a pet peeve of mine, so I could just be blowing smoke in this department!

Jelmar makes a line of CLR products, but I think it's reasonable to assume we're talking about the basic CLR liquid Calcium Lime & Rust Remover. The MSDS won't open on my tablet, but anyone who is curious could check to confirm that it is an acidic solution which does not currently contain phosphorus.

From the manufacturer's CLR FAQ:
Quote:
Can I clean my fiberglass boat, tub, or shower stall?
Yes, CLR is safe on fiberglass. Begin with a mixture of CLR and water and progress to full strength if needed.
I use CLR at home, and would certainly consider it for rust stain removal from fiberglass; however, note that the same FAQ also includes:
Quote:
CLR will take the finish off of aluminum and copper.
Our window frames are typically aluminum.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

You could always add the phosphorus back in. TSP (tri-sodium phosphate) powder can be purchased at Lowe's and probably other home improvement stores. We add a little to each load of dishes in the dishwasher, since they took the phosphorus out of the dishwashing powder too.

Yeah- I do that, too...but it never occurred to me to add it to CLR.

Thanks for the idea!

The last box of TSP I bought in Wisconsin was phosphate free . The last bag of lawn fertilizer I bought in Minnesota was phosphorous free. Many states require phosphate free detergents .. I live on a lake where many of the homes have antiquated septic systems and the outlawing of phosphates has done wonders in preventing algae from turning the lake into Pea Soup during the summer . We also are not allowed to use granular lawn fertilizer in proximity of the lake (Nitrogen) and we must maintain a 35 ft buffer zone from the high water mark inland . Times and our knowledge of the environment change

It's true that the brand "TSP" has been..."cleansed?.. of its phosphorus, but as always there's more than one way to skin a cat...

You can still get the original red box TSP. I smuggle some in from New Hampshire from time to time. New Hampshire, the "live free or die" state.

I have to live with extreme iron water in my well. Not fit for drinking or washing clothes. My Shower Stall and toilets turn orange in a week.
So I can honestly say I am the iron remediation Qween....
There was a product made by ZEP commercial concentrated iron stain remover that was very strong, is currently off market now, or I can't find it anymore. I used this and thought it much more powerful than CLR... Used to buy it in Lowes or Home Depot. Now they have replaced it with the spray version of SUPER IRON OUT Rust and Stain Remover Spray. WORKS GREAT on FIBERGLASS! Spray it on and let the magic work, no scrubbing, no touching.
Costs $4.88 Contains: Hydrofluorosilic Acid and Oxalic Acid.
