Powerful surface Cleaner
Limonene is a naturally occurring compound found mainly in the skin of certain plants and fruits, including lemons and oranges. It is used in cleaning products for two reasons: it has a pleasant, lemon-orange smell, and it acts as a solvent to help clean.

SURFACE CLEANSER – with surfactant
5% d-Limonene
5% polysorbate 20
6% surfactant of choice, including coco betaine or Castille soap
73.5% water
0.5% to 1% preservative
Mix the polysorbate 20 and d-Limonene together in a small container. In another container, mix the surfactants together – try not to get too much foam – then preservative and mix together again. Add the polysorbate 20 and d-Limonene, and package in a spray bottle.
This won’t be too foamy as the d-Limonene is an oil and the polysorbate 20 is a solubilizer, and neither of these plays well with surfactants! So we’re using their natural de-foaming and de-lathering abilities to creating a surfactant-based cleanser that won’t foam up too much!
SURFACE CLEANER with Castille soap
35 grams d-Limonene
40 grams polysorbate 20
405 grams water
35 grams vinegar
40 grams Castille soap
2.5 grams liquid preservative
Mix the first two ingredients together, then add the water, vinegar, soap, and preservative in that order. Mix well. Put into a bottle and rejoice.
SURFACE CLEANSER – rubbing alcohol-based
10% d-Limonene
10% polysorbate 20
79.5% rubbing alcohol
0.5% Liquid Preservative

Good for cleaning labels from bottles or really stubborn grease stains from my workshop table.
