LC089 -- Can Lotus Clean Magic Spray also be used when the whirlpool is full?

I have the following question about the Lotus Clean Magic Spray: Can the cleaner be used on a filled whirlpool tub to remove dirt marks, or must it be emptied?

Lotus Clean Magic Spray is a cleaner that removes grease. It contains a very small amount of surfactants. These surfactants foam. You should therefore not spray Lotus Clean Magic Spray directly into the water of the whirlpool tub. However, if you spray the Clean & Refresh onto a damp cloth and wipe the rim with it, there should be no foaming.

The fields marked with * are required.
