Customer Comment & Question Too

“I don’t have a septic tank, but bought your Eco Bleach, Eco Toilet and Eco Floor cleaner a while ago.

The products are great, and I’m just wondering whether it is possible to use the eco bleach as a pre-wash in my washing machine?”.

Why Should You Use an Alternative to Bleach with Your Septic Tank?

Regular household bleaches and chemical drain cleaners often contribute to a bad septic tank. This is because they kill the good bacteria in your septic tank. ECO-BLEACH adds residual oxygen to the tank, helping to sustain the septic tank’s aerobic performance.

In addition, as we become more environmentally aware, we learn much more about the detrimental impact chlorine bleach and similar products have on our environment – and in particular to our health, waterways and ethical issues.

Is Oxy Bleach a Good Disinfectant?

Oxy-Gen ECO BLEACH is a hydrogen peroxide septic safe bleach that kills 99.99% of household germs. As a concentrated bleach, it works effectively as a disinfectant, quickly breaking down into oxygen and water as it sanitises.

Excess oxygen dissolved in wastewater entering the septic system then helps increase healthy bacterial activity to improve effective septic waste digestion.

What is Hydrogen Peroxide Septic Safe Bleach?

Hydrogen peroxide septic safe bleach is an environment-friendly bleach that is an alternative bleach which is non-toxic unlike ordinary bleach, which contains potentially hazardous chlorine-based chemical compounds.

Hydrogen peroxide is known chemically as H2O2. It is environmentally friendly and contains natural antiseptic and bleaching properties. As it sanitises the peroxide breaks down, splitting off one Oxygen atom, into Water (H2O) and Oxygen (O).

Just One Muck Munchers Programme is all Most Households Need

Muck Munchers are perfect for household up to 6 people. For large households if you have significant amounts of washing-up, laundry, baths and showers, you may need to double the dosage.

Shared Septic Tanks

If you share a septic tank with a neighbour, we recommend that you use separate packs for each property, if the total count exceeds six people.

Keeping Inlet Drains Clean

There’s great merit in applying Muck Munchers in different toilets each month. When you flush the sachet dow the loo, a proportion of the microbes will attach to organic waste on the drain surfaces, increasing digestion and reducing the chances of blockages.

The best toilet to apply Muck Munchers initially is the one furthest away from the outlet drain to the septic tank.

How to Use

1. Sinks, Basins, Baths and Showers
Direct down waste outlet to keep germ and smell free. Leave 5 minutes and then rinse with a cup (250ml) of water for optimum benefit along drainage pipes.

2. Taps, Plugs and Overflows
Wipe with neat Oxy-Gen to deter Limescale.

3. Cleaning Worktops, Floors and Waste Bins
Dilute 40mm in 2 litres of water. Wet surfaces with solution and wipe off excess. Allow surfaces to dry.

4. Bleaching Whites
Add 25ml to 10 litres of water. Soak overnight, then rinse thoroughly.

Sorted My Shower Waste and My Saniflo

Every time we flushed the Saniflo, waste came up in the shower in my daughter’s bathroom. Following your advice, I put a Muck Munchers sachet in the Saniflo and left it overnight, and used Digesta in the shower and wash basin each day. In a few days all was flowing freely. The plumber had quoted £600 + VAT for a new Saniflo, so it was £43 well spent with you.

Saved a Lot of Money on Pump-Outs

I have been using Muck Munchers for nearly three or four years now and have not had to have my septic tank pumped out in all that time. This has been a great money saver as previous to using Muck Munchers the tank had to be pumped out annually. I must have saved more than £300 by using Muck Munchers in my septic tank. Thank you, Muck Munchers!

A Healthy and Odour-Free Septic Tank

I used to have a single stinky drain and despite every effort to check and understand why every so often an unpleasant smell would waft around in the breeze. Then I heard about the Munchers family and what good work they do so I gave them an opportunity to prove themselves and boy, did they ever! In a matter of two weeks, the smell disappeared and has never returned since. On a calm and quiet day, if you put your ear to the tank cover you can hear the sounds of a party. They truly are happy in their work and continue to be so to this day.

Far Less Sludge and Tank Smells Better

I wanted to let you know that we had our annual service and inspection of our Klargester bio filter this morning. The engineer said he’s never seen it in such good condition and significantly less sludge than in previous years – he even said it smelt much better than most units. I wasn’t tempted to verify this!!

Oxy-Tonic Bio Accelerator – the Answer to Septic Tank Smells

I have had issues with my tank for many months. I use other products from Muck Munchers but this was the first time I had purchased this. I did not completely follow the instructions as I tipped the whole bottle into the main tank and wow what a difference no more odours and no issues with the system sensors failing due to muck getting on them. I will certainly purchase again.

Eco-friendly Toilet Cleaner – Harsh on Stains

Having moved into a house with a badly stained toilet, I tried several cleaners that didn’t work. Having to be careful because we have a septic tank I tried Eco Toilet and it did a fantastic job. Have been using it for over a year and will continue. Great product.
