how to remove hard water stains in acrylic bathtb

Have a dirty looking area on bottom of my acrylic(from Re-Bath) and am sure it is from our hard water. Tub is just now being used daily. Know I cannot use regular products like CLR or Lime Away. Have tried ammonia, vinegar, baking soda and a mixture of all 3-no luck. Any suggestions?

Unfortunately, Lime Away and CLR and Clorox and toilet bowl cleaner and Scrubbing Bubbles and Soft Scrub and TSP and Bar Keepers Friend Stovetop Cleaner (one of the best things for this) are all out for acrylic tubs - will etch or dissolve the surface.


Tide plus some bleach will work but is still mildly abrasive.


Safest thing is Dawn liquid dish - make up about a 10-20% solution and wipe/sponge or spray (in an old window cleaner bottle) it on and let sit for 15 minutes, then use some elbow grease and sponge it out. Heavy buildup may take a couple of passes to remove, or may have to mix with white (not brown - can stain) vinegar. This will take out the brownish scum layer (which is mostly soap scum) so you may need to use a bit of white vinegar to get it squeeky clean. The key with fiberglass/acrylic tubs is to clean them weekly, and monthly or so put a wax coat on the sides (NOT the bottom where you stand) - see manufacturer instructions for wax recommnedations, but Johnson's Paste wax LIGHTLY applied is what I have seen most recommended probably - some recommend Pledge spray table wax which is certainly easier to apply than a paste wax, but I don't know if the cleaners in Pledge will hurt some acrylics - I would not take the chance. The wax sheds the water faster, hence you do not have dirty water standing and drying on the surface, causing the scum.


Here is a list from BathFitters of things they recommend - but there are at least 5 types of plastic/fiberglass compositions used in bathroom fixtures, so what is safe for theirs may not be for yours. I would certainly stay with only the main brandname products (Johnson & Johnson, Clorox, P&G, Church & Dwight, etc), and only if they specifically say safe for acrylic fixtures.
