Where it Works

Use it in your kitchen drain.
NOTE: If your kitchen sink has a garbage disposal, do not use Drano® Professional Strength Crystals Clog Remover. Try Drano® Dual-Force® Foamer Clog Remover instead.

How it Works

Thanks to its unique churning action and heat, Drano® Professional Strength Crystals Clog Remover works to melt and break down grease, so it’s great for stubborn kitchen clogs. You only need a small amount to get the job done, so one container lasts a long time.

After 15 minutes, pour cold water down the drain. If drain is still clogged, repeat application. Do not repeat after second application. Consult a plumber.

Use one tablespoon weekly as directed to keep drains running freely.

Never cover drain. Keep hands and face away from drain and children away from sink area.

Keep Drano® drain openers and solutions of Drano® away from eyes, skin and clothing.

Keep water out of can at all times to prevent contents from violently erupting or boiling out.

Never use or mix with other drain cleaners or chemicals before, during or after using Drano® drain openers since Drano® may still be present if drain did not completely clear and Drano® may react with such products.

Never use with plunger or pressurized drain opener (splash back of lye can occur).

Even after use, Drano® drain openers may still be present if drain did not completely clear. Do not use in garbage disposers, dishwashers, toilet bowls or in pipes directly connected with such devices.

Keep off all surfaces, fixtures and utensils made all or in part of aluminum, wood, paint, acrylic or fiberglass.
