Guinea pig stinky bedding

[dontstopmenow]

Hello all you veteran piggie owners. I'm hoping you can help me out, we have just become the proud owners of two girl guinea pigs. They are young so live inside. I am struggling with the smell of the cage and the quantity of used bedding I have to dispose of.
I have tried using a thick layer of wood shavings all over cage which was the best for minimising smells but creates stacks of waste and our bin gets full up of our waste without adding in theirs.
I then tried lots of newspapers on floor of cage and paper bedding on top for sleeping on which was very smelly with all the wee and I was changing it twice a day.
I know that I wouldn't be able to cope with the upkeep of fleece bedding so please can anyone advise on what works best for indoor piggies??!!
Thank you so much in advance!!

Wow! I just checked back to lots of replies, thank you all very much! Lots of ideas to work my way through. I have at the moment a huge bale of this

To use up first.
I cleaned them out earlier so hoping they can go till Sunday before needing a whole new bed as I'm working all weekend. I will give fleece more consideration too but I have a feeling that with the way my washing mountain is anyway, it wouldn't work for us. We will also work our way through everything else till we find what works for us.
They are lovely lottle things though and I am glad we got them!

We use newspaper and back 2 nature or care fresh or a mix of both. Put the bedding in the compost bin. Mixed with food waste it rots quite well.

We clean out once a week.

We use megazorb after it was recommended on here. Dries out really quickly so doesn't hold a damp smell. In my opinion is better than shavings. I've not tried paper as the cost seems extortionate!

As above, we used to use Megazorb from our local petshop. Is better on their respiratory systems then wood shavings which can be dusty, plus absorbs the smells. We used newspaper at the bottom then megazorb then lots of hay.
