when i do insides.. i leave the bucket obviously at one point .. depending on the size of the job.. may not work for you but this method saves time and is in effect more effective... when i visit the bucket i take anything between 4 - 7 microfibre cloths.. wash and wring them out as much as poss.. put them in my pouch ( unger ergo ) and have a double BOB ( 2 buckets on the belt joined together) you can either take a waaga type bottle full with water and LITTLE soap.. for when your applicator dries up... but in effect for quality its best to use a washed out applicator IMO.. because your only adding water to the applicator and not washing the dirt off.. which means your cloths and applicaor will get even dirtier...another method is to use a two buckets.. one full with warm water the other empty to carry 2-3 applicators all washed out in oblong bucket so that the water does not run down to one side. the empty bucket can also be used to throw the dirty cloths when you return to the bucket to wash them out.. sounds strange but keeps the windows cleaner because your using clean cloths for every window and a fairly clean applicator (s) too.. this will save your hands also.. i dont recommend putting detergent in the water for the microfibre cloths.. too much soap in these is a pain to work with and will also knacker your hands ( cracks etc ) just run some diluted detergent over the applicator.. when washing the applicators first the soap will run into the bucket anyway then you can wash the cloths... trrust me this will make you move quicker because istead of using one cloth that will get dirty and wet fast your using several (up to 7 ) plus it will save your back and time because you wont have to keep visiting your bucket... use a dry microfibre ( preferably a big one 70 x 90 cm or something like that ) for detailing or some good scrim.. make sure your using the best squeegees for the job.. and i prefer the unger green micro fibre for insides it goes longer and there are less drips... what i mean to say is it seems to stay wet longer than the other brands IMO.
i probably clean inside better than anyone else on this forum ... because here in Germany its all expensive houses and both inside and out... next week ime gonna buy the Sorbo quadropod... bucket stand why.

its saves my back and another major point what people have missed .. IT lOOKS DAMN PROFESSIONAL... also when leaving your bucket in one place put a cover on the ground to stop water getting on the floor.. this will save you stress and also look professional to the customer.. but first and foremost will save you worrying about wet foorprints and wet floors when you leave which could.. be noticed by the customer. hope this helps mate
