Hi Nic, No problem this concept is simple to use and very effective and because you are using the cloths just damp with water there is no mess, if the glass surface is very dirty i can also offer you Beyond-kleen which is the safest and most effective glass and mirror cleaner available on the market today, contains no IPA,ammonia,alcohol, just spray a small amount onto the damp little waffle microfiber glass/mirror cloth and proceed to clean surface, then use a second little waffle cloth dry to polish off for a perfect streak free,grease free,lint free finish, if i can be of any further assistance Nic, please just let me know.
