factors you must consider before buying a toilet drain cleaner

Type of drain you have: You must consider the type of drain you have in your toilet before buying a drain cleaner because most drain cleaners are made of chemicals which may destroy the drains in the toilet if you do not choose the right one.

Type of clog: This is another very important point to consider before making the decision on the type of drain cleaner to buy. Most toilets are clogged by either cotton balls, dental floss, hair, or paper towels, which should never have been flushed down the toilet.

When choosing a drain cleaner, some cleaners are designed to get rid of specific clogs, so, take that into consideration before making your decision so you can buy the type that will ensure the clog has been removed completely.

What I mean is that; you shouldn’t buy a drain cleaner that is used to eliminate grease clogs for your toilet, because you do not expect your toilet drain to be clogged by grease.

Cost: It is important to consider cost. Most of these drain cleaners are generally not expensive, but you must understand that you shall receive what you pay for. The extremely cheap cleaners may not be as powerful as the expensive ones, but it doesn’t necessarily mean that you pay through the teeth for a drain cleaner. It simply means that you must have cost as one of the factors to consider.

Final thoughts on the Best Drain Cleaners for Toilet

Drain cleaners are great in unclogging your toilets, but they need to be used with care.

Always ensure you use protective gear whenever you use these drain cleaners. This is because a single drop of sulphuric acid or granule of sodium hydroxide can be very painful on the skin. You should invest in heavy duty gloves, an apron, and even some eye protection.

Have a window open whenever you are dealing with acidic drain cleaners. This is because they normally fume right out of the bottle, and it is very dangerous.

Finally, do not be too scared to use the drain cleaners, these points are simply a precaution so you do not cause any more problems than you already have.
