Notes
Optional: first spray the tub with 50-50 vinegar and water to soften soap scum. Scoop a little onto a sponge and scrub; rinse well.Safety: wear gloves (washing soda is caustic to skin); tea tree oil is toxic to pets; if adding peroxide, store in a vented or loosely capped jar out of light (it can build pressure).
