Drain Cleaner for Old Pipes – Buying Guide

Let’s quickly go over some advice, tips, and info that you can use to choose the best cleaner for old pipes.

What it Can Power Through

The first thing you always want to look for when choosing a drain cleaner is what the product in question is designed to eat through. Most of these products will be able to eat through anything organic. The product you get should be able to handle all manners of food, grease, hair, and anything else which might be in your drain.

Chemical vs Enzyme

Another thing to keep in mind here is whether you want to go with a chemical formula or an enzyme based formula. Enzyme based formulas are quite eco friendly and can usually eat through most clogs just fine. However, the chemical drain cleaners are much stronger, better at unclogging, and much faster acting too, although they definitely are not eco friendly.

Intended Application

You do also need to pay attention to the intended application of the product. Everything we have reviewed here today is safe for old pipes and drains. However, be careful when choosing drain cleaners for toilets, as most of the products reviewed today, as well as most drain cleaners in general, are not toilet safe.

Viscosity

Something else to look for is a drain cleaner with a thick formula. Thick drain cleaners can cut through standing water and will really adhere to clogs, so the clogs get dissolved without the product simply running right down the drain past the clog.

Safety Tips

Wear gloves when using these products, as most are super corrosive
Use these products in a well ventilated area to avoid inhaling fumes
Always read the instructions and safety warnings before using any drain cleaner
