The answer to 'best drain cleaning' is using a combination of chemical and mechanical methods to effectively clear clogged drains. Chemical drain cleaners can help dissolve organic matter, while plungers, augers, and hydro-jets can physically dislodge and remove blockages.
For minor clogs, homeowners can try using a plunger or baking soda and vinegar to clear the drain. However, for more stubborn or recurring issues, it's best to call a professional plumber who can inspect the drain, identify the root cause, and use specialized tools and techniques to fully restore proper drainage.
