## Description

Product Description HG Duo Unblocker is a two-component drain unblocker for persistent kitchen and bathroom blockages caused by oil, food, soap scum, hair and other common debris. Bottles A and B work together inside the drain to help break down build-up and restore normal water flow. Use it as a kitchen drain unblocker and kitchen sink unblocker for oil, grease and food residue, or as a bathroom sink unblocker, bathroom drain unblocker, shower drain unblocker or bath drain treatment for hair and soap scum. It is also suitable for compatible utility sinks and waste pipes. This ready-to-use drain pipe cleaner requires no dilution and is designed to work without excessive foaming or splashing. Dosage depends on where the blockage is. First remove standing water. For kitchen drains, carefully pour 1 measure of bottle A followed by 2 measures of bottle B. For bathroom drains, use 2 measures of bottle A followed by 1 measure of bottle B. Leave to work for at least 1 hour; for stubborn blockages, leave overnight where possible. Rinse thoroughly with plenty of water. Then pour the remaining liquid from bottle A followed by the remaining bottle B into the drain as a follow-up treatment. Leave for another hour and rinse thoroughly again. The formula also works as a plughole unblocker for suitable kitchen, bathroom and utility drains. Designed for households dealing with persistent blockages, its two-part formula provides different measured doses for kitchen and bathroom use. Always follow the bottle measurements and label instructions. Do not mix with other cleaning products. Wear protective gloves and eye protection, keep out of reach of children and read the label before use. Includes bottles A and B of HG Duo Unblocker.

## Questions & Answers

**Q: can i use this with a septic tank?**
A: I don't have a septic tank but I do have a "Biodisc" digester instead of mains sewerage. I've used Duo four or five times over about the same number of years and it has not caused any problems. It also does the job far better than anything else 've ever tried.

**Q: Can use this for the toilet? Would it damage the white ceramic bowl?**
A: Good afternoon,

Please be informed that HG "duo unblocker" must not come in contact with the ceramic bowl. It must be pourred carefully in the drain, to avoid any damage of the surface.
However in case of a toilet we can not guarantee that the blockage will be solved. The blockage could be too far away or the product will be diluted too much by the water in the toilet drain.

with kind regards,
HG consumerservice

**Q: is this suitable for outdoor drains?**
A: Good morning,
Please be informed that this product is not suitable for outdoor drains.
We do not have an alternative product in our product range which can be at your assistance.
Trusting that we have informed you sufficiently,
with kind regards,
HG consumerservice

**Q: Can this be used in a washing machine? to help clear hair blockage?**
A: No, this is not suitable for use in a washing machine or dishwasher.  We would suggest using HG Service Engineer which is designed for use with washing machines and dishwashers.
