Anything to clear small fat berg in U bend of Kitchen waste?

Heedtheadvice

Yes, prevention better than cure!
However a cure is required.
Caustic soda granules (main active ingredient of most expensive drain cleaners) is both cheap and effective.



:Note: This is not the same as washing soda!


Pour a few desert spoonfulls (in quantity, best not to use cutlery though!) down the sink waste adding warm (not hot water as it is an exothermic reaction and will generate heat) and leave till fat dissolves and water runs down the pipe. Will clear most organic matter.

Repeat if necessary.
Complete the action with a sink full of warm water, detergent and some more caustic soda to then flush through.


Take care. Caustic soda is as the name suggests caustic. Use 'rubber' gloves keep off skin (or wash off immediately) as it turns skin into soap!!, Out of eyes off clothes etc. Unsure it is cleaned from anything it comes into contact with after use including the sink.

IT is probably good that this outside Ubend is catching it.

If the u-bend is outside (I didn't read it like that) then it shouldn't be, move it indoors or it will block everytime the temperature drops below freezing.

Hairdressers get 40% hydrogen peroxide on their hands on a daily basis (from experience) it's really not as bad as this

That v40 hairdressing stuff is only 12% by volume, while it will not burn like acid I would not want to get it on my hand as it will burn and make skin patchy. Think it is also used to lighten skin and anal bleaching too.

It generates a lot of oxygen in reactions. Used a lot in food stuffs. Looks like the 35% stuff is classified as a precursor and you can no longer buy it over the counter and you did have to show this concentration some respect.

Personally the plasric bends are cheap, just put new bends on as others say

My sister used to work as a women's hairdresser, many years ago. Her fingers were so affected by that stuff that she's had totally smooth finger tips ever since. She couldn't leave a finger print if she tried.

Its a strange burn, it turns white for a bit and itches like mad. My hands look much older than their years from the constant shampooing and bleach burns

Yes, the OP is not clear ("lifting some of the fat out with a empty baked beans tin" sounds like it could actually be a gully outside, not a narrow bore waste pipe).

But the bottom line is that any drainage system which needs regular maintenance like that to avoid blockages is poorly designed (or being abused) and the right solution is to have it modified to prevent a repeat, or modify use. If the OP is doing everything possible to avoid putting fat down the sink then a picture of the problem might help us give some advice on what changes might need to be made.

I'm not a fan of chemical solutions - you don't really know what damage you might be doing, and if there is a blockage the last thing you want is to have to deal with pipes full of aggressive chemicals.

I use caustic soda with boiling water to clear my drains. If you are careful, you will be fine.

Just pour a small amount of caustic soda down the plughole and follow through with boiling water from a kettle. Slowly pour the kettle around the side of the sink at arm's length. Keep pouring slowly as you hear caustic soda work its way through the pipe work. Then finish by rinsing the sink out with cold water.

I was trying to imagine an external sink waste & trap. As with EachPenny, the OP must be meaning the gully. Most do have a U bend that traps smell. The correct method is to avoid using chemicals, they are so dangerous in the wrong hands. I suspect that the OP is uncertain in how to dispose of fats & solidified cooking oils.
Don't pour down the sink hole or gully. Instead get at much as possible into your rubbish bin or save for making fat balls for the birds.
If any fat/oils remain in the cooking pan (if liquid) add some detergent a litte water mix into an emulsion (or absord with kitchen roll, expensive and not MSE), this can then go down the drain. If the fat has solidified then heat it up and do the detergent tip.
