Just filled a new tub for the first time. Day one it was clear. Day two red rust film on bottom and sides. What is this and how do I get rid of it?
Thanks,
Kelsey

could be from metals in your water. Look for something like Metal-Gon or the like and dump it in your water.

removing rust from your tub using house hold products:
1. Pour or rub white vinegar or lemon juice onto the stain.
2. Let the liquid stand until the spot or spots disappear.
3. Rinse area with fresh water.
4. Repeat steps if necessary.

another homemade rust remover solution is a cup of Borax mixed with the juice from one lemon. This mixture makes a rust remover paste that can be applied directly to the stain. It should sit for twenty to thirty minutes and then be scrubbed clean.
