Baby wipes are good, for getting most of the accumulated shite off of the bike, you could do that in the kitchen over some newspaper, but they won’t get grimey rims/brake blocks clean enough IME…
it’s an outside job, with bucket of warm soapy water and an old washing up sponge/scourer jobbie, wheels off and give them a thorough scrubbing and rinse, then have a good go at the brake blocks…
Chain off first of course though, shake it about in a jam jar full of your preferred cleaning agent; meths, white spirit, petrol, diesel, badger spittle… to rinse and re-lube later
