Applying a small amount of the diluted solution to a low-visibility corner and waiting a few minutes allows the user to confirm that the tiles and the surrounding sealant will not suffer adverse reactions. Once safety gear is in place and the test area proves successful, the workspace is ready for the cleaning phase.

This involves cutting out the old material and applying fresh compound.

How often should this deep cleaning process be repeated?
