Fiberglass Scouring Cleanser
A stronger scouring blend for fiberglass surfaces with built-up soap scum, using salt as a gentle abrasive.
What you'll need
- 1/2 cup baking soda
- 2 tbsp fine salt
- 2 tbsp liquid soap
Steps
- Combine into a thick paste.
- Scrub stained areas with a soft brush.
- Rinse well with warm water.
Tip: Skip the salt on any hairline-cracked fiberglass — it can work into the crack.
