Soak the grout with hot water. Hot water will help break apart the grout and aid in its removal. Saturate the grout for a few minutes before continuing.
Mix the washing powders and hot water together in the 1 gallon bucket. Add 1/2 scoop of powders to 1 gallon of hot water.
Saturate the grout with the soap mixture. Allow the washing powder mixture to set into the grout for 5 to 10 minutes.
Remove the large chunks of grout using a metal dental pick. Be gentle when picking the grout away, as you can damage your tub's finish if you are not careful. The hardest part of this step is patience.
Dip a fine-textured scouring pad into the soap mixture and gently scour the remaining grout away. Keep the grout soaked with the soap mixture while you work.
Wipe away any remaining residue using a stiff sponge soaked in the soap mixture. Repeat steps 5 and 6 until the grout is gone.
